  1. Put on eye protection and a mask or respirator that will filter out mold spores, such as an N-95 mask, if you have heavy mold infestation.

  2. Dampen the moldy surface using a spray bottle filled with water. This will minimize the number of airborne mold spores and limit the spread of mold and the chance of associated health problems.

  3. Fill a bucket with a non-ammonia soap or detergent and warm water.

  4. Wear rubber gloves and dip a scrub brush into the solution. Scrub away the mold.

  5. Pour 1 gallon of water into another bucket. Add 1/2 cup of bleach.

  6. Using a sponge, wipe the surface with the mixture. Allow the solution to remain for 15 minutes.

  7. Rinse the sponge with clean water and wipe the surface to remove the solution. Wipe the surface with a towel to remove as much moisture as possible. Set up a fan to blow directly on the surface to help it dry rapidly.

Tips

To avoid mold and mildew in the future, keep the relative humidity (RH) level of your home between 30 and 50 percent. There are dehumidifiers and RH meters that can read your home's relative humidity. In addition, be sure to clean up excess moisture and condensation wherever it occurs, such as on shower walls and above stove tops.

Warnings

It will be almost impossible to remove mold from porous materials, such as carpet padding, so you should consider throwing away these materials.
