Besides the awning, I was thinking about how it might be good around the house. I have about 200 feet of block retaining walls that have black and green junk growing on them. Also the north side of my house and shed need help, as well.

It has bleach in it so be careful when using something like this with any kind of stitching. Personally, I wouldn't use it on an awning unless you have a mold issue and I would keep it away from any stitching.
