Just did the awning on the weekend. Used a garden sprayer to apply a solution of water, bleach and degreaser, rolled it up and left it overnight. It didn't do much. So I reapplied the solution, used an extension pole and the brush and washed the top first from the roof of the 5er and then the underside. I had to use magic erasers on the harder spots while on a step ladder. As I retracted the awning I got the top side from the step ladder. Now it is clean except for some small non mold stains from pine needles.
