I have an aluminum sided 2 story house. The north side has moss or some kind of green stuff grown in bloches. I plan on power washing it off as soon as the weather warms up. My question, is it ok to power wash siding and is there a right or wrong way. Also is there something I can apply so it doesn't come back.
