Hello,

My house has older aluminum siding on it. It chalks if you rub it. In
a few places I noticed some green algae on the siding. Whats the best
way to get rid of it? I don't want to power wash because it might
take the color off the siding. Any suggestions?

Forgot to mention in my other post: When done bleaching, rinse DOWNWARD with
a light spray, to avoid shooting water behind the siding.



What about "pool shock"?

powerful stuff!!!!
use with extreme care!
