How Can I Get Black Mold Off My Deck Railing?
Black mold is a greenish-black mold that grows on areas that have experienced leakage, flooding or excess moisture. Black mold can cause health problems and is particularly challenging to remove from wood, since it is a porous surface. Stubborn cases of mold may require two or more treatments. The Environmental Protection Agency recommends hiring a professional if you have more than 10 square feet of mold growing on your deck and railing.
