How to Clean Mold on a Wall
- 1). Put on gloves, face mask and goggles.
- 2). Fill bucket with very warm water. Add a cap-full of laundry detergent.
- 3). Saturate the cloth in the detergent solution, then wring it out. Scrub the mold-stained area vigorously. If the mold isn't scrubbed away, switch to a scrub brush and scrub vigorously. Rinse the area with clear, warm water. If the mold has been completely removed, allow the area to dry completely, and you are done.
- 4). Mix a solution of 1 cup of chlorine bleach in one gallon of water, if there is still mold that couldn't be removed. Fill the spray bottle with the solution.
- 5). Spray the mold-covered area with the chlorine solution, wetting it so thoroughly that it will take at least 15 minutes for the area to dry, so that the solution has time to kill the mold. Allow it to dry.
