The Best Way to Clean Mold From a Wall

Chelsea Fitzgerald

Mold can show up on walls in homes where the air is often at 70 percent humidity or higher or where condensation occurs, according to the North Dakota State University website. Condensation occurs on basement walls or in bathroom areas while bathing or showering and in kitchens while cooking. Mold growth can cause unsightly stains on the walls and often has an offensive smell. Many people are sensitive to mold. Children, senior citizens, people with respiratory problems or pregnant women are particularly susceptible to developing sensitivities. Clean the wall surfaces to get rid of the mold.

Rubber gloves and sponges are effective in cleaning moldy walls.
  1. Ventilate the room with the moldy walls by opening a window or running an exhaust fan. This helps get rid of the offensive odor from the mold and allows fresh air into the room so you don't breathe in the mold spores.

  2. Wear rubber gloves and goggles to prevent the cleaners from irritating your skin or getting into your eyes. Wear an Occupational and Safety Hazard-approved mask to prevent breathing in mold.

  3. Mix a mild dish-washing liquid or a mild laundry detergent with warm water. Wash the moldy wall area with the warm, soapy water. A sponge is effective in washing the wall. Allow the wall to dry.

  4. Pour 1/4 cup of regular household bleach into a clean bucket. Add 1 gallon of water.

  5. Dip a clean sponge into the bleach solution and wring it out well. Wipe the wall area with the sponge, covering all the surface affected by mold. Allow it to sit for 20 minutes and repeat the step. Wait another 20 minutes before proceeding.

  6. Pour approximately 1 cup of a borax detergent into a gallon of water. Allow the borax detergent to dissolve. Wipe it on the wall area with a damp sponge and allow it to dry on the walls. This prevents recurrence of mold growth.
