We identify and eliminate the causes
Even if there is no fungus in the rest of the apartment, everywhere is clean and dry, it can appear in the bathroom. This room has ideal conditions for its appearance - high temperature (above 20 ° C) and high humidity (norm up to 70%).
There is only one way out in this case - to improve ventilation or somehow quickly reduce humidity. Humidity is reduced:
- with the help of recuperators (devices that collect moisture from the air);
- increasing the efficiency of ventilation.
Check the health of the ventilation duct
If there were no problems with mold before, it is necessary to inspect the ventilation duct. Perhaps it clogged up, because after taking a shower or bath, high humidity is removed from the room for a long time. It is easy to check the operation of the ventilation duct: take a piece of paper (even a notebook sheet or a piece of newspaper), somewhere in the apartment you open a window a little (for airing). In the bathroom, bring the sheet to the ventilation grill.
If the leaf is attracted to the grate - everything is fine, if not - the channel is clogged. It is necessary to call the appropriate service for them to clean it.
Air supply
If there is craving, but also the fungus, we continue the tests. It is necessary to do the same operation again - bring a piece of paper - it is also necessary with the door closed to the bathroom. If in this case there is no traction (the leaf is not attracted), but with the door open it “stuck” to the grate, the door is installed too tightly. There must be a gap of at least 3 cm for the air flow at the bottom. The second option is ventilation grilles for air flow.
They crash into the bottom quarter of the door. If you do not want to change the doors, you can choose matching plastic grilles and install them yourself. Other ways to improve ventilation in the bathroom are to make a ventilation hole in the wall opposite the outlet of the ventilation duct (at the bottom, just above the floor level) or to stretch the ventilation duct / pipe in the same place. In general, in this case, the task is to ensure the flow of air into the bathroom to activate air exchange.
Traditional methods
Most of the folk remedies allow you to get rid of the external manifestations of the fungus for a while. You will remove traces of it from the surface, but its spores will remain in the material. And if so, that after a while the spots will appear again. Only a radical solution to the problem of humidity can help - effective ventilation. In a dry room, mildew / mold cannot develop.
The use of means harmless to humans
Ordinary vinegar and baking soda will help get rid of mold in the bathroom. There are several methods of using them:
- Wipe the walls with alcoholic table vinegar, leave for several hours, closing the doors, rinse with water, then ventilate.
- The way for horizontal surfaces is to pour soda, pour vinegar, wait until the reaction ends and rinse with water.
- Wipe the walls first with baking soda, then with vinegar, then with water.
It is difficult to say how effective these mold remedies will be, but vinegar from hardness salts helps perfectly - white bloom is washed off without a trace.
The next folk remedy for fighting mold in the bathroom is peroxide. They also wipe the walls with it. But we must remember that peroxide in large quantities is toxic and it is necessary to work with a mask and gloves. Also, do not forget that it has a whitening effect. If you grout in the joints between the tiles, it will become a few shades lighter.
Hazardous substances
In the first place in terms of frequency of use - bleach and chlorine-containing agents for cleaning plumbing - Belizna, Domestos, Duckling, etc. They are diluted with a certain amount of water, the walls are coated, especially carefully processing the seams between the tiles. External manifestations (dark spots) go away very quickly, literally before our eyes. For some time after treatment, the mold does not appear, but sooner or later (usually in the autumn or spring season), it begins to show through again.
It is necessary to work with bleach and preparations from it with gloves, a respirator and protective clothing. After processing, it is advisable to turn off the ventilation (if there is a forced one), close the doors tightly, do not use the bathroom for a while. Chlorine in a free state is not for long, but at this time it is very active and its vapors as well. Such a "gas" chamber will allow you to disinfect the corners that cannot be reached with a brush.
The next most popular way to get rid of mold in the bathroom is treatment with a solution of copper sulfate. Take 100 grams of powder, dissolve in 10 liters of water and treat the walls and ceiling with this solution. The precautions are the same as when using bleach. The results, in principle, are also not very different - temporary getting rid of black marks.
Store funds
There are many different anti-fungal compounds in any hardware store. They differ in the spectrum of action and method of application. There are products that are distributed with a brush or roller, there are aerosol containers or with lever spray guns. Some formulations require the use of protective equipment (gloves and a respirator), others are harmless to humans. In any case, read the instructions before starting work.
