We have a wooden deck. It’s made out of treated lumber, and hasn’t been cleaned since we moved in (4 years). It’s starting to look pretty grungy, and there’s spots where there’s greenish slippery algae kind of stuff growing.
So we want to clean it. Seeing as both my parents and my brother own power washers, we’ve got that part covered. But when Mr. Athena talked to my brother about how to use it, his recommendation was to buy some sort of “deck cleaner” stuff and/or bleach.
We’ve got little dogs, and we’re perched on a hill above a stream. We’re just not all that into putting that much chemically stuff into the environment or our dogs. Sooo… what are our options? Anything “green” that will help?
