Mildew is a common fungus. Indoors, it is most commonly found in humid areas such as bathrooms, basements and anywhere with low air circulation and high humidity. This can include wooden baseboards behind furniture, windowsills, and closets. Spores produced by the mildew can travel through the air, causing an allergic reaction in some. Therefore, mildew should be removed when noticed, and steps taken to prevent it from returning in the future. Luckily, it is fairly easy to remove mildew from interior wood. Read on to find out how to do it.
Mix up your cleaning solution. This will not only clean the wood, but kill any mildew on the wood. Fill a large bucket about half full with warm water, then add a capful of laundry detergent and 1/4 cup bleach.
Put on gloves, goggles (especially if you are working with any mildew in high places) and long sleeves. Open any nearby windows, and turn on any fans. Both mildew and the cleaning solution have strong odors.
Dip your scrub brush into the cleaning solution and scrub the mildew until it is gone. You should be able to scrub fairly briskly without damaging the wood.
Rinse the area with clean water, and dry with a rag or let air-dry.
Consider applying a layer of mildew and mold resistant paint or varnish to the wood to discourage future mildew growth.
