How Do You Clean Mold Off Concrete Basement Walls?

To clean mold off concrete basement walls, the homeowner must mix a solution of one part bleach to three or four parts of water and apply it to a scrub brush or a sponge to scrub away the mold. The cleaner must wear safety goggles to protect the eyes from getting splashed by the bleach, and rubber gloves are required to protect the skin and hands. Proper ventilation and a mask also help protect the homeowner from bleach fumes and mold particles that become airborne during the cleaning process.

After the walls are thoroughly scrubbed, the area must be completely dried and checked for any additional mold growth. Additional mold stains come off with a mold/mildew stain remover, which is available at supermarkets and hardware stores.
