Black mold (Stachybotrys chartarum) commonly occurs in many households. Well-known for the health hazards its presence can cause, black mold can take root and spread in porous home-building materials such as drywall. While widespread mold growths often require major house modifications or reconstruction, minor mold growths also occur in specific areas. As black mold needs moisture to grow, it is frequently found on and inside of refrigerators and freezers. Fortunately, as these appliances have nonporous surfaces, removing the mold is relatively simple, though it requires safety precautions.
Put on the goggles, rubber gloves and N-95 protective mask to protect from the bleach.
Open a nearby window to ensure adequate ventilation while cleaning with bleach.
Dilute the bleach in a bucket. Mix 1 cup of bleach with 1 gallon of water.
Mist the moldy surface lightly with a spray bottle to prevent spores from spreading while you clean.
Dip the washcloth or towel into your water-bleach mix.
Wipe the surface clean with the washcloth.
If the surface of your freezer is rough, scrub it with a brush and your water-bleach mix.
Rinse the surface with clean water.
Let the surface dry.
