Removing Mildew

Mildew stains often make an appearance in damp locations, such as bathrooms and basements. Before painting, you'll need to eliminate this black, speckled growth to make sure new coats of paint adhere well.





Step 1

Step 1: Remove the stains using mild detergent or sandpaper Test the stains by washing with some warm water and mild detergent. Ordinary stains
will wash out, but mildew won't. If the stains don't wash out, gently sand them out with
150-grit sandpaper.

Step 2 

Step 2: Use rubber gloves and eye protection before you wash walls with bleach Use a mold and mildew removal solution to eliminate the spot. Most will take about 2 hours to dry fully and will eliminate the mildew stain entirely. Sometimes, on surfaces like caulking, removal may be more difficult. If the area is wet, ensure that it is dry before and for at least 2 hours after application to allow the solution to properly work.
