I just picked up a newer boat and it has a full enclosure. The PO had left it outside in the yard over the winter leaning against a tree. It is an off white top bu is now green with mold and mildew.I tied to clean it with some soap, water, and a scrub brush. I even power washed some of it. I is cleaner but I would like to get it better. Can I put it in the wash at the Laundromat with some colorsafe bleach and detergent?
