White mold is usually found on basement floors because the right environmental factors for its growth, including moisture, nutrients and mold spores, are present. After cleaning up the mold, controlling excess moisture in the house is recommended to stop mold growth.
Using protective equipment, such as rubber gloves, a respirator mask, eye goggles and a coverall, is recommended when cleaning mold to reduce exposure. It's best to use a stiff brush and hot, soapy water to scrub the moldy area of the floor. After scrubbing, rinse and dry the area thoroughly. Finally, spray the area with a bleach solution of 1/4 to 1/2 cup of bleach per gallon of water, and allow it to dry.
Determining the source of moisture helps prevent recurrent mold growth. Having the basement floor and walls checked for leaks is recommended. Water can easily seep through small cracks, so it's important to repair any problems promptly. It's also important to ensure that gutters are in working order and water runoff is directed away from the house. If the weather is hot or humid, using an air conditioner or a dehumidifier helps remove excess moisture from the air. In addition, keeping the house warm when the weather is cool helps reduce condensation.
