Moisture will cause wood and other particles to decay, making the ideal habitat for mushrooms and mold. Fungi will grow on wood, dirt, paper and even soap scum. Although major infestation may need professional guidance, there are a few tricks you can try to remove the fungi from your basement.

Things You Will Need

  • Water
  • Nonammonia soap
  • HEPA vacuum
  • Bleach
  1. Put on a respirator, gloves and eyeglasses when working to prevent spores from getting into your lungs. This can cause an allergic reaction.

  2. Remove visible mushroom heads by pulling them up as close to the surface they are growing on as possible.

  3. Scrub the area with a nonammonia soap. Allow the surface to dry.

  4. Vacuum the surface with a HEPA grade vacuum to remove all dirt particles from the area.

  5. Sand wood areas that have the mushrooms growing on them to remove the spores, if scrubbing has not removed the spot. Sand using 80 grit sandpaper to slowly remove layers of wood until clean.

  6. Disinfect the surface with a mixture of bleach and water. Mix 1/4 cup bleach into 1 gallon of water in a bucket. Rub the surface with the solution and allow to stay wet for 15 minutes so that it has a chance to work on the spores. Rinse the surface with water and allow to dry.
