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?
Spray bottle with 10% bleach & water. Hit the hardware store for a soft
brush on a broomstick. Home Depot has a selection of broom-style brushes,
all of which fit the same broomstick. Choose one soft enough to not scratch
the siding. And, ***WEAR GOGGLES*** and a hat.
