Spring is finally here, and with it, many houses have green and gray stains on their vinyl siding. This is algae, mildew, and mold. It grows best on the north side of the house because that side is away from the sun. It is worse in years with a lot of rain. There is a product that removes these stains with very little work. It is a product called Wet & Forget. It removes mold, mildew, and algae stains gently over time from roofs, concrete, brick, siding, tennis courts, awnings, boat sails, and wood decks without scrubbing or pressure washing.Ā
