How can I remove lichen and/or mold from plastic siding?
Spring Cleaning? An effective way to clean mold &amp; mildew off aluminum or vinyl siding! After a lot of researching the web for various methods, I simply used one scoop of Oxy-Clean and a cap full of laundry detergent in about 2 gallons of warm water. The soft bristle brush, about 4 ft. long, is the kind used for applying roofing cement, etc.

Just spray rinse, wash with soapy water and rinse again. Works great!
