Things You'll Need

  • N95 respiratory

  • Rubber gloves

  • Safety goggles without vent holes

  • Long sleeve shirt

  • Pants

  • Work boots

  • Cloth or sponge

  • Warm soapy water

  • Bleach

  • Water

  • Bucket

  • Spray bottle

  • Stiff brush

  • Mild dishwashing liquid

  • Fans

Point fans in the direction of the wood to aid in the drying process. If mold is still present, use a fine grit sandpaper to sand away the area on the wood that is infected with mold.


Before beginning the mold removal process equip yourself with the proper safety items: An N95 respiratory mask, rubber gloves, safety goggles without vent holes, long sleeve shirt, pants and work boots should be worn at all times during the mold removal process. Do not mix bleach with ammonia or any products containing ammonia.

Removing mold from wood can be difficult.

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.
