I recently posted a plea for help to remove mold/grime from an awning that's only 6 months old. got some answers but none of them worked, ie, bleach, Simple Green, etc. any other ideas?
50/50 bleach & water works great on my great on my 14 year old awning. I spray it down, roll it up for 15-20 mins, and then roll it out and hose it off. Are you sure it's mold/grime that you're fighting? Have you tried to scrub it any?
