How to Clean Black Mold off the Walls in a Bathroom

A bathroom free of black mold is safe to use.

Black mold on your bathroom walls is not just unsightly; if left unattended, it can be bad for your health. Black mold should be removed from your bathroom walls at first sight, before fast-growing mold spores have a chance to spread. Use supplies from home or the store to clean and remove black mold from your bathroom walls. Once completed, diligently keep your walls clean to help prevent the return of black mold.

Things You'll Need

• Spray bottle
• Water
• Measuring cups
• Disinfectant cleaning liquid
• Bucket
• Cleaning cloths or scrub brush
• Hydrogen peroxide

Instructions

1. Mist the bathroom walls where black mold exists using a spray bottle filled with plain water.

2. 

   Using a bucket allows you to move around with your cleaning solution.

   Prepare a cleaning solution for the first part of mold removal: Fill a bucket with hot water and add 1/4 to 1/2 cup of liquid disinfectant cleaner. Mix the solution to create some soap suds.

3. Dip a clean cloth or scrub brush into your disinfectant cleaning solution. Scrub your bathroom walls that have the black mold infestation. Remove as much black mold as possible. Change to a fresh cleaning solution when the water starts to look dirty, and continue washing your walls until black mold is no longer visible.

4. Combine 1 part hydrogen peroxide with 2 parts water in a bucket. Saturate a clean cloth with the peroxide solution and wipe down the walls where the black mold existed. Rinse your cloth in the peroxide mixture frequently to ensure you are getting the peroxide on the wall surfaces. Wash surrounding areas as well. The peroxide mixture will kill any remaining invisible mold spores and help to prevent its return.

5. Dry your walls completely using a clean dry cloth. Open windows, as well, to aid in the drying process.

Tips & Warnings

• Substitute chlorine bleach or isopropyl alcohol for the hydrogen peroxide if necessary when killing mold spores.

• Use a ventilating fan each time you shower. Keeping moisture to a minimum will help prevent the development of black mold.

• Excessive black mold infestation on your bathroom walls can spread to the insides of walls. Consult a professional for mold removal as this type of mold can be very toxic.

• Wear safety goggles and rubber gloves during the black mold removal process.
