We were looking at our awning that has a little mildew. Someone at a campground told me that he uses a 50% mixture of Simple Green in a spray bottle. He then roles the awning up for 30 minutes. After ...
Simple Green had 2-butoxyethanol (EGBE) at ~4% or less until last year. As of right now, it's pretty safe to use though.
Do you guys have to put a lot of elbow grease into scrubbing mildew off when using Simple Green? Does it stay off pretty good or does it return pretty fast?
