Now if I could only get a self cleaning house. Most years I only have to scrub the Algae off of this shaded wall twice a season. This year I've already done it 3 times and now it needs it again. Even my string hammock has Algae all over it. I'm afraid to bleach that as it might rot the strings. Any less caustic suggestions? I would hate to put it away like that. It is now a light green color, not at all white.
