Black mildew stains can show up on many different surfaces including fabrics, upholstery, rugs and wood.  Mildew is a growth produced by mold that tends to develop in moist, humid and dark conditions.

The warm summer months are ideal for mildew stains to form inside closed homes.  Mildew thrives most on cotton, silk, linen, wood and paper.

Mold can cause serious damage in the form of discolored fabrics, produce a musty odor, and eat into fabrics to the point of the fabric rotting and falling into pieces.  Remove black mildew stains before serious damage is done.


Fabric Mildew Stains

  1. Add 2 tbsp. lemon juice and 1 tbsp. salt to a pint of water in a spray bottle.
  2. Spray the mildew stain on the fabric. Allow the solution to soak into the fabric.
  3. Rinse the fabric in cold water.
  4. Repeat Steps 1 through 3 until the mildew is completely removed.

Upholstered Furniture and Rug Mildew Stains

  1. Remove loose mold from the surface with a broom.
  2. Vacuum the surface to remove the mold spores.
  3. Empty the vacuum bag outdoors to avoid spreading mold spores in the home.
  4. Sponge lightly with liquid detergent.
  5. Wipe the surface clean with a cloth moistened with water.

Wood Mildew Stains

  1. Dry the wood as thoroughly as possible using a blow dryer.
  2. Add 8 tbsp. trisodium phosphate to a gallon of water in a bucket. Trisodium phosphate can be purchased at most home and hardware stores.
