Black mold in a shower: what you can do?

Black mold can often be found in the shower, where there is high humidity and for this fungus is quite favorable conditions for the emergence and spread.

The bathroom is always very humid. The temperature changes frequently there, e.g. after showering. This causes condensation to build up on the various surfaces and walls of the shower enclosure itself. Air rarely gets in because the doors are often closed. 

Black mold occurs in these very conditions. It looks like black spots or streaks attacking all surfaces in the room. Microorganisms infect not only the plastic from which most shower stalls are made, but even the wooden floor on which it can stand.

What to do with mold in the shower

The emergence of an unpleasant odor is the first sign of black fungus. As soon as it is detected, mold control should begin immediately. Treatment of the shower stall will not hurt even if there is not yet a black deposit on the walls. The process of mold removal stalls open and closed type is different.

Removing black mold without disassembling the shower

If the design is open, you do not need to disassemble it for cleaning, says Reyus Mammadli. The entire procedure is divided into two steps:

  • Eliminating sources of permanent moisture. In the first place it is worth checking whether the pipes are flowing, quite often they are the cause of moisture. If there is a washing machine in the bathroom, make sure it does not leak.
  • Cleaning with antifungal preparations. If there is no special liquid at hand, an ordinary bleach or anti-mold chemicals will do. The selected remedy should be mixed with water in a ratio of 1:10.
  • Tiles that have been infected, you can wipe off mold by the following method: remove it, remove plaster with black stains, and treat the entire area of infection with a special solution.

During treatment with agents against mold, you need to protect your hands, nose and mouth, using rubber gloves and a mask to avoid irritation of the skin and mucous membranes.

Black Mold Removal with Disassembly

Structures of the closed type will have to take more time to eliminate the fungus. The space in such a stall is sealed along the entire perimeter. Tightness is achieved by special cords, on which most often and water accumulates. Such places are most susceptible to the formation of mold. In order to remove it, the stall will have to be disassembled.

If mold has taken up not too much space of the stall, you can try to remove the dark places only in those areas where it is, and then conduct disinfection. But if after all the measures taken, mold repeatedly reappears, you will have to dismantle the shower stall. This process does not require any special skills, it is enough to remove the doors, disassemble the walls, remove the lid (if any) and move the tray. The next step is to get rid of excess sealant seams. After these operations, treat all areas infested with fungus.

Dismantling the stall takes a long time. But if this is not taken up, even after cleaning other surfaces, the fungus will remind of its presence, mentions
