Anybody have any luck with a store bought product? I'd like to clean the black mold off of my roof this weekend. FYI, I'm not going to use the zinc strips as I am going to replace the roof in 2 or 3 years. And what about getting it off of vynil siding? I just did my house with a regular (Krud) cleaner and I had to scrub the living hell out of it. Is there a product that will keep it off of the siding? TIA
