How do i clean my bathroom ceiling which has gone black with mould because of condensation ?
First fix the problem at the source– find a way to get the moisture out of the bathroom. If you have a window, make it a habit of opening it to vent out the moisture, of course if you have an exhaust vent, use it every time a shower is taken. If no window or exhaust vent, have an exhaust vent installed to get rid of the moisture. Once you have solved the moisture problem at the source, then use rubber gloves and rags dipped in bleach water to clean the mold off. You may have to use a sealer on the walls and ceiling, and repaint to get rid of mold that has penetrated and won’t be impacted by bleach. Good luck. If you don’t address the moisture source by venting, you will continue to have the same problem.
Normal anti-mold preparations contain bleach which is deadly to life forms and bad for our lungs. The active ingredient in bleach is chlorine which is really vicious stuff. Occasional exposure is OK but not for long times or often. Frequent application of bleach to paintwork can damage it and, after a while, cause flaking and peeling. Vinegar is equally deadly to black mold but not to people. The acid in vinegar kills the mold. White vinegar is best and is sold in most supermarkets. Borax is also very effective and safe. High humidity and low light levels are ideal for black mold growth. If your bathroom has a window to outside light and air, let these in as much as possible to prevent the growth of mold. Cleaning black mold off paintwork, between tiles and in the corners they so love is best done as follows :- Spray white vinegar (or the vinegar and borax mixture from the recipe below) onto the mold and allow it to soak in for 15 minutes. Particularly thick layers of mold need working
