How to get rid of black mold in the bathroom. How to get rid of mold in the bathroom

The bathroom is a place where there is always a lot of water. Consequently, the room is constantly humid. If you neglect the rules of care and do not monitor the state of ventilation, then soon you can find the appearance of unpleasant black spots. The fungus not only spoils the appearance of the room, but also threatens the health of the household. Of course, the prevention of such a phenomenon is much more effective, but with an already arising problem, it is important to know how to remove the fungus in the bathroom so that it does not bother you anymore.

What is a fungus

In common people, a fungus is compared to a disease. Only the victim is not a living creature, but walls and other surfaces in a humid room. The fungus is made up of microorganisms that prefer dark, damp, but warm places. Therefore, the bathroom is an ideal breeding ground.

But the main danger of black spots is not only cosmetic defects and untidiness of the room. The main reason why it is important to know how to remove fungus in the bathroom and prevent it from reappearing is the effect of microorganisms on the health of people and animals living in the house.

If a fungus lives in the bathroom, then it can cause:

chronic rhinitis;
persistent cough that does not respond to treatment;
asthma attacks;
incomprehensible localization of headaches;
rashes on the skin.

It is important to understand that the problem is not in the fungus as such, but in its disputes. It is they who, getting into the surrounding air, have a detrimental effect on a person.

Where does it come from

The bathroom is always humid. However, not everywhere there is such an unpleasant phenomenon as a fungus. Why this happens and how to remove the fungus in the bathroom, we will consider further.

The following surfaces are most suitable for the reproduction of microorganisms:

the plastic that is so popular;
concrete or:
stone.
wooden furniture.

It is necessary to understand that various kinds of microorganisms constantly live in the air, but conditions are required for their reproduction. If they are not there, then they cannot multiply and, accordingly, be distributed throughout the room.

Therefore, it is important to monitor the condition of the air in the bathroom, keep ventilation in good condition and avoid dampness.

Action on detecting mold

When a fungus is found in the bathroom, every homeowner is worried about how to remove it. But before starting the fight against microorganisms, a number of important measures should be taken. If they are neglected, all further efforts will go to waste. The fungus will disappear, but very soon it will be found again.

Check and rectify any malfunctions in the ventilation system.
Treat the washing machine with disinfectants. Next, run it several times in idle mode with any descaler.
If there is wooden furniture in the bathroom, then it will have to be thrown out. The fact is that the tree is an excellent breeding ground for spores and it is almost impossible to get them out of there.
If the house has old pipes, the best solution would be to replace them with plastic ones. If this option is not yet possible, then it is necessary to start isolating the existing ones. This is necessary so that condensation does not accumulate on the surface.
Check all plumbing for serviceability. All leaks must be ruled out.
If there is a wall that borders the entrance, it is better to insulate it.
The bathroom door must have ventilation openings. A way out of the situation may be the gap between the door leaf and the floor.

Only after all the conditions are fulfilled can you directly fight the fungus.

Popular remedies that have proven to be effective

There are quite a few remedies that successfully fight black spots in the bathroom. Their effectiveness has been proven by numerous reviews of housewives, but it is important to observe precautions.

Copper sulfate

Many are interested in how to remove the fungus in the bathroom with copper sulfate. It does its job well, but requires careful use. The procedure is as follows:

We dry the bathroom. To do this, you can use the existing heater. The door is still open.
A solution is being prepared. For this, a tablespoon of vitriol is taken for one bucket of water.
We put on gloves. It is advisable to cover your face with a gauze bandage.
We process all the affected areas with a wide brush.
After that, it is advisable to leave home for 3-4 hours.
The treated areas are well washed with warm water and wiped dry.

The method is effective, but re-processing may be required. It is important that there are no children and animals in the house while working with vitriol.

How to remove fungus in the bathroom with hydrogen peroxide

The product has antibacterial properties and is suitable for those who cannot use copper sulfate. However, with its help, you can remove spores, and even then only if they have not spread much and do not take up much space.

This method will be especially effective if you are concerned about how to remove the fungus in the bathroom between the tiles on the wall. Also suitable for plastic furniture and rubber inserts.

Before processing, it should be noted that hydrogen peroxide has bleaching properties. Therefore, it is recommended to use it on light-colored surfaces.

The essence of processing is simple. It is enough to put on gloves and use a cotton swab to process the tile joints, the affected furniture. Leave to act for 10-15 minutes and rinse well with warm water. It is necessary to carry out several treatments until the spores are completely destroyed.

Tea tree oil

How to remove fungus in the bathroom with folk remedies worries those who cannot use potent drugs and are prone to allergic reactions. In such cases, you can use tea tree oil.

For this, a solution is prepared, consisting of one part of oil and one part of warm water. The resulting liquid is poured into a spray bottle and the cracks on the tiles, the space between the bathroom and the wall, are treated. The product is absolutely harmless and therefore does not require rinsing. The processing is repeated as necessary.

The oil not only destroys spores, but also gives the room the pleasant aroma that the bathroom lost when the fungus started in it. However, it must be understood that it is possible to completely get rid of the unpleasant odor only if the mold is completely removed.

Chlorine bleach joins the fight

Many people are interested in how to remove fungus in the bathroom. Anyone will help get rid of it forever. But ordinary bleach is considered the best option.

Due to the fact that when working with it, harmful vapors are released, a bandage on the face and gloves are necessary. For processing, you will need to prepare a solution. To do this, take one part bleach and ten parts water. The amount of liquid is determined according to the scale of the disaster.

Processing order:

a solution is being prepared;
using a spray or a wide brush, the product is applied to the blackened areas;
leave to act for two hours, while it is necessary to open the windows and leave the room;
after that, everything is washed with warm water;
complete drying is important, so the surfaces are thoroughly wiped;
the bathroom is ventilated.

It is important that there are no children or pets at home during processing.

Industrial drugs

When there is no desire or opportunity to use folk remedies, it is better to take advantage of the inventions of the chemical industry. The possibilities of the drugs are quite extensive, their effectiveness has been proven by numerous applications, and the safety is confirmed by the manufacturers.

On sale you can find household options for combating fungus and industrial ones. The latter must be used during construction in order to pre-treat the surfaces in the bathroom and thereby avoid problems in the future. Household ones are suitable for eliminating spores that have already appeared.

On the shelves in the store there are both imported and domestic products. What to prefer depends on the desire and financial capabilities. But, judging by the reviews of consumers, both of them effectively fight the consequences of the appearance of the fungus.

If you are concerned about the question of how to remove fungus in the bathroom from the ceiling, then it is better to use special means offered by the chemical industry. The use of bleach and copper sulfate is also permissible, but their use in a hard-to-reach place is difficult. In any case, it is better to take the drug with a spray.

Risk-free cleaning

Many people are worried about how to remove fungus in the bathroom. In this case, the methods must be non-aggressive and safe. You can use the following tips.

Soda and vinegar. An effective and cheap tool. Ingredients can be found in almost any home. The essence of the method is as follows:

The soda is slightly moistened with water to form a paste.
The resulting product is applied to the affected area.
After that, a few drops of vinegar are slowly poured onto the paste.
After the formed foam has settled, everything is washed with warm water and wiped dry.

The method is harmless and does not require the removal of household members from the apartment.

Boric acid and acetic essence... Before work, you should wear rubber gloves and follow the instructions:

Prepare a solution. For this, 4 parts of water, 2 parts of hydrogen peroxide, 2 parts of boric acid and one part of vinegar essence are taken.
Use a brush to treat all affected areas.
Leave to act for 3-4 hours.
Rinse thoroughly with warm water and wipe dry.

After using the product, it is necessary to ventilate the room.

Preventive measures

So that the question of how to remove the fungus in the bathroom does not stand in front of the household, it is necessary to observe preventive measures. Otherwise, even the most potent remedy will be powerless to end the problem once and for all.

You can purchase a special fungal spray from the store. They are treated with the air in the room if the condition of the bathroom is of concern.

You also need to be especially careful about faucets and showerheads. They are often invaded by microorganisms. To prevent this from happening, you should periodically process them with a vinegar solution prepared according to the 1: 1 scheme.

Conclusion

If you do not neglect the rules of hygiene, keep the plumbing in order and regularly inspect the ventilation system, then the fungus will not attack the bathroom. However, if this has already happened, then using the methods given in this article, you can get rid of it.

Molds coexist with humans everywhere and are able to survive in any environment, even at subzero temperatures. But the active reproduction of fungal spores begins only with poor ventilation and high humidity. The bathroom often meets these conditions, therefore it is found all the time.

The rapid development of mold begins with a prolonged combination of the following conditions:

air temperature from 20 ° С;
air humidity above 70%;
poor ventilation of the room;
stagnant dirt and expired household cleaning products (power source for molds).

The bathroom is a favorite habitat for black mold: it is here that the humidity is increased almost constantly, and air exchange is often insufficient.

To completely get rid of mold in the bathroom, you need to find and eliminate the cause of its appearance. As a rule, these are places of stagnant water that are not always visible.

Possible sources of excess moisture accumulation:

faulty plumbing - dripping taps and broken communications tightness (often water stagnates under the bathtub or shower tray);
gaps at the joints between the tiles and the bathroom (or shower);
condensation, which forms when the temperature drops sharply on cast iron pipes, the ceiling, the cistern, on the outer surface of the bottom of the bathroom and shower tray, walls (as an option, if the heated towel rail is not heated sufficiently);
roof leaks (in apartments on the last floors), weeping walls.

Note. Darkness is an additional factor that triggers mold growth. As a rule, the walls of bathrooms in apartment buildings are deaf and light practically does not penetrate there. When arranging a bathroom in a private house, it is better to provide a window in at least one of the walls, ideally with the possibility of ventilation.

Means and methods of struggle

Long-term struggle with mold forced people to constantly look for options to eliminate it. The accumulated experience of the people and industrial developments offer a large selection of proven and affordable tools.

Household chemicals and home remedies

If the fungus is on the surface and the affected area does not exceed 10 cm, alternative methods or popular household chemicals will help to remove the mold.

Vinegar

9% table vinegar is one of the most effective home remedies for fungal infections. The vinegar is applied undiluted. After finishing the treatment, the product is washed off with water, and the bathroom is ventilated.

Soda

An aqueous solution of soda (1 teaspoon of soda per 200 ml of water) creates a caustic alkaline environment that is harmful to mold. Soda can be used in its pure form - it is non-toxic and does not form defects in processing areas.

Note: Simultaneous use of baking soda and vinegar is possible. Soda is scattered over the surface, vinegar is applied from a spray bottle on top. After the end of the reaction and the settling of the foam, the surface is cleaned with a brush, washed with water and dried.

Ammonia

Effective on smooth surfaces, but not able to penetrate porous drywall and wood. The product is mixed with water in equal parts and applied with a sponge to tiles, mirrors, ceramic and glass surfaces. After treatment, the solution is washed off with water. Ensure good ventilation during work, as ammonia vapors can enter the respiratory tract and cause headaches.

Boric acid

Antifungal effect is manifested by a mixture of water, peroxide, vinegar and boric acid in a ratio of 4: 2: 2: 1. The solution is applied from a spray bottle to tiles and plumbing fixtures.

Tea tree essential oil

It has a mild antifungal effect and is usually used in combination with other agents (vinegar, baking soda) to enhance their effect. It has an intense and persistent specific aroma.

Sodium tetraborate (borax)

An effective fungicide for use in medicine and everyday life. Non-toxic and does not require rinsing. An aqueous solution of 100 g of borax and 1 liter of water is moistened with the affected surface and cleaned with a brush.

Hydrogen peroxide

3% hydrogen peroxide solution is effective against mold fungi and is well suited for the treatment of porous surfaces and textiles.

Note: Peroxide has a strong whitening effect and can leave unwanted stains on the treated surface. Therefore, before use, the drug should be tested in a small, inconspicuous area.

Copper sulfate

Copper sulfate or copper sulfate is a powder or granules of bright blue color. An old proven broad spectrum fungicide. To treat the bathroom, it is diluted with water in accordance with the instructions on the package (as a rule, 10 g of powder is dissolved in 1 liter of water). The drug is toxic to humans and animals.

Note: Copper sulphate is reactive when in contact with metals, so it is not used on faucets or other metal surfaces.

Plain chlorine powder, Domestos and whiteness are capable of killing up to 100% of fungal organisms. The product is used to treat tiles, mixers and plumbing fixtures, hold for 10 to 15 minutes and rinse thoroughly with water. Concentrated whiteness can damage the plastic, so it is diluted with water in a ratio of 1:10. Chlorine-containing substances are sprayed onto porous surfaces from a spray bottle. When working with chlorine, a respirator and gloves are required. After cleaning, the room is well ventilated.

Benzalkonium chloride

A modern antiseptic without a pungent odor, which is recognized as safe and is included in many cleaning products. Benzalkonium chloride solution is active against most types of mold and other infectious agents, therefore it is widely used in medical institutions. For home use, the Sarma series of household chemicals is suitable.

Professional remedies

The chemical industry produces antifungal drugs that are different in composition and hazard class. At home, it is advisable to use low-toxic agents, which include:

General rules for antifungal treatment

Mold control methods often combine chemical and mechanical treatment of the contaminated surface, which is carried out taking into account the following recommendations:

Features of the processing of tile seams

Removing mold from tiles is usually straightforward. But if the fungus has settled on the seams of the tile, getting rid of it is not so easy. In this case, the sequence of actions is as follows:

Complete removal of grout from joints using a renovator, trowel or construction knife.
Treatment of the opened areas with an antifungal drug.
Drying.
Filling the joints with a new grout with the addition of a fungicidal component.

Overhaul is a radical way

If all the measures taken turned out to be ineffective and the mold reappears, they resort to its radical removal. The method requires a major overhaul, which is carried out in the following sequence:

Remove old tiles and other finishes on floors and walls.
Use a spatula to remove the affected areas of paint and plaster.
They wash the walls well and dry them with a building hairdryer or a household fan heater.
The contaminated surface is treated with a professional antiseptic fungicide. After the first layer has completely dried, the antifungal treatment is repeated.
In case of an unfavorable location of housing (corner apartment, first and last floors), a layer of coating and pasting waterproofing is arranged on the floor, walls and ceiling.
Dry the treated surfaces thoroughly again and apply an antifungal primer, for example Ceresit CT 99. If waterproofing has been carried out, the primer is selected depending on the type and composition of the waterproofing material.
Start finishing work.

Note: When replacing plumbing, control the quality of sealing of all joints and communications. If possible, use a primer, tile adhesive, sanitary silicone sealant with the addition of fungicides.

Mold prevention

Preventing the appearance of fungus in the bathroom means creating conditions in which it cannot develop. Reduce humidity levels and provide adequate air circulation in all possible ways. The following measures will give a good result:

After taking a shower, straighten the curtain in the bathroom and remove water drops from the walls of the shower stall with a special brush.
Ventilate the bathroom every day, and it is better to leave its doors ajar - always when the room is not in use. Air currents prevent mold spores from adhering to the surface. In addition, open doors increase the illumination of the bathroom.
Avoid stubborn dirt formation and periodically wash tiles and plumbing with household disinfectants (Bref, Domestos, Whiteness, baking soda or soda ash).
Do not dry wet clothes and clothes in the bathroom.
If the heat transfer of the heated towel rail is insufficient, replace it or install an additional heating source.
Monitor the condition of the ventilation shafts and, if necessary, clean them (for this, you can call a specialist from the housing office or other service organization).
Install additional ventilation in the bathroom.
It is advisable not to close the plastic windows tightly and even in the cold season set them to the minimum ventilation mode. This will improve air exchange throughout the apartment.
If possible, replace metal pipes with plastic ones, on which condensation does not accumulate.
Control the level of air humidity using a psychrometer, which can be purchased separately or in combination with other measuring devices (barometers, thermometers, electronic clocks, etc.).
Household ionizers and bactericidal lamps are used for periodic air disinfection.

A washing machine installed in the bathroom, if used improperly, can be a source of fungus. To prevent this, follow simple rules:

after the end of washing, wipe the drum dry and leave it open for several hours;
periodically run a long idle wash with a maximum temperature and additional rinsing;
when using fabric softeners, it is advisable to always turn on the additional rinse mode: a poorly washed product is a good breeding ground for mold;
do not leave wet laundry in the machine.

Why is mold dangerous?

Uncontrolled mold growth threatens serious health problems, provoking allergies, asthma, skin and joint diseases, headaches and a general weakening of the immune system. Mold spores enter the human body with air and food and, at high concentrations, cause severe intoxication.

For people with severe immunodeficiency, it is fatal to stay in a room infected with fungal spores. Allergy sufferers, children and the elderly are also at risk.

The species diversity of mold is amazing, but in everyday life the following varieties are usually annoying:

blue mold (or blue mold);
green;
black;
white;
pink;
rotting fungi (white, brown and bacterial rot).

White, green, and pink mold are commonly found on food and in flower pots. But in old houses with poor ventilation, these species are found in whole colonies on weeping walls and can settle in any room.

Pink mold on the walls of the old building.

In multi-storey buildings, black mold most often lives.

Mycelium and black mold spores.

Spores of this type are capable of infecting any surface and building material - from plastic and tiles to reinforced concrete structures. At the initial stage, the mold looks like a few inconspicuous dots, which, as it spreads, grow and merge into spots.

The fungus can even eat away floor slabs and spread to other apartments. In this case, it is extremely difficult to fix the problem on your own and you should seek help from specialists. If left unattended, plaster delamination, wall collapse and collapse are possible in areas of extensive damage.

It is not always possible to detect the fungus with the naked eye, but there are several "markers" of its appearance:

specific smell of dampness;
black (or colored) plaque or streaks on different surfaces and materials;
peeling paint or plaster;
prolonged deterioration in well-being and constant fatigue.

Mold in your home is not just a cosmetic defect. This is a serious signal of trouble. Mold does not give you time to think and in a short time is capable of destroying any building material. Only a quick adoption of adequate measures will stop the development of the fungus and, if not forever, then forget about its existence for a long time.

One of the most functional places in a house or apartment is the bathroom. A bathroom is not only a room that is visited every day by all family members for various types of hygiene and relaxation, it is also a place for washing, washing, storing dirty things. The humidity in the bathroom is always elevated, and very often everyone's favorite room becomes a source of unpleasant odor, the cause of which is mold, which is not so easy to remove.

What is mold and its causes

At its core, mold is a “plant” from the fungus family. As a fungus, mold is propagated by spores that remain dormant until the environment is favorable for their reproduction. The fungus develops in dark places with high air humidity and oxygen access. Mold grows most actively in rooms where the air "stagnates" or circulates poorly. Usually this place in the house is the bathroom.

The most common factors in the growth and reproduction of mold spores are:

faulty or insufficient operation of the room ventilation system;
temperature in the region of + 20 ° С and relative air humidity - 70-90%;
uneven heating of the room;
lack of natural light, which inhibits the development of mold;
the presence of gaps and crevices where water is retained (space under the bathroom, plastic panels, at the joints of tiles, etc.).

Unfortunately, even with only a few factors, the formation of an unpleasant "neighbor" in the bathroom is inevitable.

What is mold and the consequences of its appearance

Science knows more than 100 thousand types of mold, which can acquire different shades depending on biological characteristics. For bathrooms, the appearance of black mold is characteristic (it is most common, since its habitat is rooms with a high level of moisture); white mold (less common, but also forms on damp surfaces); and blue-green or blue mold (affects wood and other natural finishing materials, brick).

Don't underestimate the impact of seemingly harmless mold. Black mold is capable of completely corroding any building material in 1-2 years if no measures are taken to eliminate it. And mold spores that move freely in the air can get from one room to another, multiplying there.

Freely penetrating the respiratory tract of a person, mold can cause coughing, increased attacks of bronchial asthma, chronic rhinitis; deterioration of the general condition: lethargy and fatigue, hair loss, frequent headaches, rheumatic pains, intoxication, gastrointestinal tract damage; deterioration of the skin: eczema, rashes, dermatitis.
And this is just a small list of why mold is dangerous and its consequences.

What to do first

It is necessary to start fighting mold immediately. If this is the first time that mold has been seen in the bathroom, the following measures must be taken:

Check the operation of the ventilation duct. If it is clogged, then removing the blockage will lead to the removal of excess moisture from the room and a decrease in the overall humidity in the room. To reduce humidity, you can also resort to the use of recuperators (special devices that collect moisture from the air).
Get rid of wooden furniture in the bathroom, if any. Unfortunately, the tree is an ideal environment for the development of spores, the breeding of which is practically impossible.
Replace old pipes with plastic ones, or insulate existing pipes, on the surface of which condensation usually accumulates.
Check and fix all leaks and plumbing faults.
Treat the washing machine with disinfectants.
Remove all visible molds by mechanical cleaning using sponges and brushes, as well as personal protective equipment such as gloves and a respirator. It is advisable to dispose of the used improvised means after cleaning.

Having fulfilled all of the above conditions, you can take up the direct fight against the fungus.

The most common mold control products

Finding black spots on the walls or ceiling in the bathroom does not always mean that expensive repairs are ahead. A large number of the most inexpensive remedies, which can often be found at every housewife or at a nearby hardware store, have been proven to be effective in fighting mold. The so-called folk remedies have strong antifungal properties and are successfully used to kill fungi.

Hydrogen peroxide is available in almost every first aid kit. Peroxide treatment includes applying the solution to areas affected by the fungus, and treating the surface one and a half hours after the solution has completely dried. Peroxide is toxic and has a whitening effect. All towels, rugs and other colored items must be removed during use.

Copper sulfate(or copper sulfate), successfully used in construction, is a good mold fighter. For this, 100 grams of blue powder is dissolved in 10 liters of water. The affected areas are washed with soda, then a solution of copper sulfate is applied. The treated areas should dry well, after which they can be washed. Gloves and a respirator are recommended when using toxic copper sulfate solution.
Ammonium is an antiseptic with pronounced antifungal properties. Because of the pungent odor, it is recommended to dilute the ammonia with water, and then spray on surfaces infected with the fungus. To avoid feeling unwell and headaches, it is advisable to ventilate the room well after using this product.

Soda and vinegar, like hydrogen peroxide, are found in every home. To remove mold, large quantities of soda must be poured onto prepared areas and covered with vinegar. After a while, when the foam has settled, the surfaces can be washed with water and any detergent.

Boric acid taken in a proportion of 500 g of powder per 10 liters of water. You can add 500 g of borax and a few tablespoons of vinegar to the solution. Processing involves the use of a spray bottle or a regular sponge. After two or three hours, the solution must be washed off with water and the surface must be wiped dry.

Furacilin grind into powder (about 20 tablets) and mix with warm water in a container for a spray bottle. After complete dissolution of the powder, the moldy areas are treated with the composition, and after 30-40 minutes they are wiped dry.

Tea tree oil inferior to its predecessors due to the high price, however, it is it that can destroy the mold forever. 10 ml of oil is dissolved in 500 ml of water. The resulting solution is applied between the seams of the tiles, on the surface of the pipes, between the joints. Rinse off the product is not required, since it is harmless. Among other things, the oil has a pleasant aroma, refreshing the bathroom.

Chlorine(or chlorine bleach) emits harmful fumes, but fights the fungus "with a bang." Add 10 parts water to one part of the bleach. The solution is sprayed or applied with a sponge. A couple of hours after treatment, the surfaces are washed with warm water and dried. When working with bleach, thoroughly ventilate the room.

Store-bought fungus control products

In addition to folk remedies, shops are replete with various creams, powders and gels containing chlorine or alkali, designed to fight pathogenic flora. Here is some of them:

Olimp Stop Mold does not contain chlorine and other toxic substances. It is used for painted walls, concrete, brick, wood and other surfaces. Harmless to humans and animals.
Veksa- a product from a Russian manufacturer based on active chlorine. Suitable for various surfaces and has a powerful whitening effect.
Czech remedy Savo has a spray and kills fungal spores instantly. The use of a respirator is recommended due to the pungent odor.
Antiseptic Biotol safe for the body due to the absence of chlorine and other toxic substances, it is produced in the form of a liquid concentrate.

Prevention methods

A full-fledged repair made in the bathroom, including the removal of the existing finish, followed by treatment of the surfaces with special anti-fungal agents, can permanently get rid of the annoying fungus. However, it is important not only to get rid of the pest, but also to prevent its appearance. It doesn't take a lot of effort:

dry towels outside the bath or install a high-power heated towel rail;
monitor ventilation and regularly ventilate the bathroom;
keep your plumbing in good working order;
install, if possible, a warm floor;
gaps and cracks must be repaired.

Ignoring black spots in the bathroom can play a cruel joke on human health. A few simple manipulations are able to cope with an unpleasant "neighbor", forever saving the bathroom from this problem.

A beautiful bathroom isn't just about fashionable ceramics, unique designs or sophisticated furnishings. First of all, it is a well-groomed look, which is sometimes quite difficult to achieve, because high humidity is the cause of mold. Let's consider how to remove fungus in the bathroom so that the walls and ceiling sparkle clean and are safe for health, and what preventive measures can be taken to prevent a disaster.

Causes of mold in the bathroom

Oddly enough, but mold spores are constantly present in almost any room, as they easily move through the air. They do not always develop, because special conditions are necessary for the formation of colonies - heat and high humidity. That is why it is impossible to meet living foci of mold in a country house frozen over the winter or in a constantly ventilated room. The bathroom, on the other hand, seems to be created for the reproduction of spores: the heating system maintains the required temperature, and the humidity arises from the constant use of water.

If you do not pay attention in time to small black dots in the corners and at the joints in the bathroom, at the seams between the tiles, in the future the hearths will grow in all directions

The fungus can choose almost any surface as its habitat, from wood to plastic and even silicone sealants. As soon as the air humidity overcomes the threshold of 90-95% (and 70-80% is considered the norm), as spores, getting on a damp surface, begin to germinate, forming small colonies. In the future, if they are not removed in time and do not get rid of excess moisture, small black or greenish specks will turn into extensive foci, constantly increasing in volume.

It is easy to recognize the appearance of mold - it is enough to catch the smell of dampness and fungi. It smells like that in cellars and damp basements. Colonies of the fungus germinate not only on the walls - dark spots appear on furniture, the back of the washing machine, below the shower tray, where condensation is a frequent phenomenon. Condensation occurs when the air temperature drops sharply in a wet bathroom. Steam under these conditions is deposited by water droplets. This damp surface is an excellent breeding ground for mold growth.

There are many varieties of molds that are afraid of ultraviolet radiation. They begin to develop in the dark corners of the bathroom. The lack of windows in the bathroom and insufficient lighting are another reason for the growth of fungus.

Excessive humidity and stagnation of warm air, as well as the darkness that mold loves so much, is created with constantly closed doors, when natural ventilation and free air circulation are impossible. The ventilation system in rooms with high humidity should be forced, and in private houses it is recommended to build in at least a small window for ventilation.

According to building rules and regulations, when carrying out repairs and construction work in the bathroom, bathroom or in the kitchen, an obligatory step is to carry out antiseptic treatment of all surfaces with special compounds that prevent the appearance and growth of mold fungi on the surface and inside the floor and wall materials. Waterproofing of the floor and walls is also mandatory, preferably the ceiling in the bathroom. These measures protect the premises from excess moisture.

Latent leaks caused by faulty plumbing equipment and communications, when water drips and seeps little by little into walls and floors, contribute to dampness and the growth of mushroom stains.

Why the fungus is dangerous

There are quite a few varieties of fungus, but all of them can be conditionally divided into three large categories: blue fungus, rotting and moldy. The first variety is not scary for city bathrooms, as it is formed on wood, especially on pine products. Brown, white and bacterial rot also threaten the tree, and it is almost impossible to get rid of it. In urban conditions, it is worthwhile to be wary of mold, which can appear on concrete, and on brickwork, and on paint. Sometimes he cleverly hides under the tiles, so his appearance can be overlooked. In one to two years, black mold is able to corrode concrete, other building and finishing materials.

Mold spoils the appearance of the finish, is dangerous for building structures, but the main harm from its appearance is a threat to human health. Volatile substances enter the human body through the respiratory tract and cause a whole range of dangerous diseases, the use of contaminated bath accessories causes stomatitis, thrush, mycosis, asthma, allergic reactions, dermatoses and even joint diseases. Sometimes a signal that a fungus has started in the house can be incessant headaches.

How to avoid high humidity

Before removing the fungus in the bathroom, it is necessary to create such conditions under which it would be impossible for its reappearance. Of course, the air temperature cannot be changed, therefore it is necessary to reduce the humidity. To do this, you need to check for leaks or places where water accumulates. Often, a small crack in the pipe causes a puddle that does not dry out that is out of sight, for example, under a bathtub or in a corner behind a washing machine. Accordingly, if leaks are found, they must be eliminated.

The necessary air circulation in the bathroom is achieved in the traditional way - using an exhaust ventilation device, while an additional fan can be installed in the hood

The second thing to do is to establish ventilation. The air must circulate freely in the space of the room, for this there are exits to the ventilation shafts. If natural ventilation is disturbed, you should think about installing a forced one, for example, installing a special device in the ventilation opening. Also, do not turn the bathroom into a dryer - in this case, the appearance of mold is guaranteed. Preventive measures will protect walls and furniture from fungus, and residents from diseases.

How to get rid of mold in the bathroom

If, nevertheless, mold appears, you should immediately get rid of it, otherwise the colonies will begin to spread throughout the bathroom, moving from walls to ceiling, floor, mirror, pieces of furniture.

First, in any case, it is necessary to mechanically and chemically remove foci of mold, rinse black dirt from walls and tiles, baseboards and taps, cabinets and shelves with antiseptics. Dispose of rags after removing stains. Clean surfaces can be treated with antiseptics.

Along with the "grandmother's" methods of destroying harmful fungi, which consist in treating infected surfaces with the means available on the farm, there are cleaning technologies with special aggressive antiseptic solutions. Let's consider both options.

If you immediately pay attention to the appearance of the fungus and do not postpone the process of getting rid of it indefinitely, the work on removing the mold will take a minimum of time and effort.

Popular folk remedies

Careful owners have developed safe and effective methods of getting rid of the fungus over many generations of successful mold control. All means for this can be found in every house and apartment. These are simple and inexpensive tools:

White vinegar

A remedy effective for removing small colonies of fungus is ordinary white vinegar, which zealous housewives always keep in reserve for cooking or cleaning the room. This product is natural, absolutely safe for health, the only thing that will remain after its use is a specific smell, which will also disappear soon.

How to use vinegar to remove mold:

Pour vinegar solution into a spray bottle or blot with a cloth.
Apply to affected areas and leave to dry;
clean the surface with a stiff brush.
Rinse with clean water.

There are many varieties of vinegar, but to fight mold, you need the one we use when cleaning an apartment - ordinary white vinegar, without aromatic additives and herbs

Ordinary vinegar is capable of destroying up to 80% of various types of mold, therefore, despite its safety for the human body, it is a real weapon against fungus.

Baking soda

Soda is an absolutely safe remedy used in everyday life. A solution of one teaspoon of soda in a glass of water must be applied to the surface, it does not need to be washed off completely, it prevents the re-development of pathogenic microflora.

No longer in the refrigerator, but in the first-aid kit, you can find another effective remedy - hydrogen peroxide. It has an antibacterial effect and does an excellent job of killing small colonies of the fungus. Peroxide can be used to clean not only tiles, bricks or concrete, but also removes plaque on furniture, plastic and rubber surfaces. One thing to keep in mind is its light whitening effect, useful for removing mold stains but unnecessary for cleaning dark plastic. The procedure is the same as for using vinegar.

Despite the fact that hydrogen peroxide is not toxic, its high concentration (over 3%) can cause skin burns, therefore gloves should be used when using a strong solution.

Ammonia

Ammonia has a pungent odor and works great on smooth surfaces such as tiles or glass, but is ineffective on porous materials. An hour after application, it should be washed off with water.

Tea tree oil

Tea tree oil is safe, it is a natural antiseptic with antibacterial properties and a pleasant scent. You do not need to rinse off the solution.

Copper or iron sulfate

Copper or ferrous sulfate is very effective, but toxic to humans, therefore, treatment with this solution must be carried out in compliance with chemical safety measures. The solution must be washed off with water after a while.

Boric acid

This product has an effect, especially in the following combination: water, peroxide, vinegar, boric acid in a ratio of 4: 2: 2: 1.

Household chemicals

Household chemicals also have the necessary properties:

Laundry bleach works similarly to chlorine, but the concentration of the active substance in it is much lower, so the treatment is carried out several times. It can corrode the skin of the hands, so the use of gloves is advisable.
Household cleaners containing chlorine or saturated chlorine will kill mold. Bleach should be applied to fungus stains with gloves and a respirator.

The most dangerous of these agents is chlorine, so be sure to wear gloves and ventilate the area when using it.

Market overview of professional antiseptics

Professional means for removing fungus appeared in stores relatively recently, and before that they used solutions that are a kind of poison for mold. Some of them, by the way, are quite dangerous for humans, therefore, before using them, it is necessary to take protective measures: put on overalls, gloves, and in some cases, a respirator. During the processing of the premises, children and animals should not be in the apartment at all.

Before starting work, the size of the disaster should be estimated. A few black or brown dots do not cause much concern; a construction knife and a swab dipped in plumbing detergent are enough to destroy them. Large lesions that have grown by 10 cm or more require a serious approach.

If the foci of mold have reached enormous sizes, and the fungus has begun to spread deep into the walls and penetrate into neighboring rooms, it's time to call a team of professionals

You can destroy fungus or mold in the bathroom with an antiseptic compound. Manufacturers of chemical and paints and varnishes produce special agents against mold and mildew, democratic in cost, but very effective in use. As a rule, they can be easily found on the shelves of building supermarkets.

The smoke penetrates into all the smallest cavities and crevices, hard-to-reach places and kills all mold and rot, fungus spores in the air. After such a procedure, the bathroom becomes completely safe.

Mold destruction on the vine

If all these measures do not lead to the desired result and the fungus appears again, then the lesion is under the decoration or in hidden cavities inside the walls and you will have to resort to drastic measures. The same technique should be followed if antifungal cleaning is carried out during the repair process.

First, you need to identify and mark the areas affected by mold, while taking into account the possibility of hidden foci. Remove trim from walls or other surfaces.
Moisten open foci of fungus with water to prevent spores from entering the air.
Spray an antiseptic or apply an impregnation against the fungus, capturing not only stains, but also a clean surface, treat with an ionizer checker.
Wait until dry and repeat the treatment the required number of times.
Clean the walls with a wire brush or putty knife and remove dark fungal stains and remnants of old finishes.
Soak the clean surface again with an antiseptic, waterproof, if necessary, with a coating, impregnating or roll material. Waterproofing in the bathroom should be installed not only on the floor, but also on the walls, and in extreme humidity, the ceiling.
Re-lay the tiles using a waterproof grout with antifungal additives, or another finish, paint, under which an antiseptic primer is applied.

Mold prevention measures

After repairs, it is necessary to regularly carry out simple preventive work and follow the rules that will protect residents from the reappearance of any biological damage.

With the help of such measures, which can be carried out on their own, the bathroom and kitchen will become favorite places in the house, where households relax after a hard day at work or conduct useful water procedures, will be completely safe for health, sparkling clean and comfortable.

Effective prevention - forewarned is forearmed

The best way to deal with mold colonies is to prevent mold colonies. To do this, the owner of the bathtub will need to fulfill only two conditions - to reduce the temperature and humidity in the room. Moreover, this can be done in several ways. First, increase the air exchange rate. This will increase the inflow and outflow of air, as a result of which both the humidity and the temperature in the bathroom will decrease. Moreover, to scale the air exchange rate, you only need to increase the fan power in the exhaust zone or expand the dimensions of the exhaust duct.

Secondly, reduce the area of the heated towel rail. This will keep the tub cooler and the mold will not have a comfortable temperature for the colony to develop quickly. However, this measure can also affect the comfort of users, therefore, instead of installing a smaller heated towel rail, the homeowner can arrange an insert of a regulator that controls the volume of the flowing coolant, being able to regulate the temperature in the bathroom at his own discretion.

Third, fix all leaks. The source of water vapor can be not only a shower or a full bath, but also a leaking joint on a plumbing fixture fitting or a crack in the pipeline. By eliminating leaks, you save on water bills and get a relatively dry bathroom. In addition, you need to give up the habit of drying out the washed laundry in the bathroom.

Consider these tips and mold won't bother you for a very long time after you finish cleaning walls and seams with cleaning products.
