When mold fungus is found growing on wood you should kill it as soon as possible. Mold is not only unsightly and potentially dangerous, but it can also ruin wood. If left untreated, wood infected with mold will deteriorate and eventually become unusable.
Step 1
Open windows and doors to provide better air flow and ventilation during mold removal.
Step 2
Dampen a soft cloth or sponge with warm, soapy water.
Step 3
Wipe off as much of the surface mold as you can with the cloth.
Step 4
Combine 1 1/2 cups of bleach with 1 gallon of water. Pour the mixture into a spray bottle.
Step 5
Spray the wood liberally with the mixture.
Step 6
Scrub the area with a stiff brush. Allow the wood to dry completely.
Step 7
Combine water and a mild dishwashing liquid. Saturate a cloth in the mixture.
Step 8
Scrub the wood with the saturated cloth. Allow the wood to dry.
