I use a mixture of Dawn liquid dish detergent, Bleach, Simple Green, water and spray it on using a garden sprayer then roll it up for 20 - 30 minutes then unroll and rinse. If real bad I rub with the wash brush before rinsing and sometimes if it was really bad I repeat the process. Either way I let dry thoroughly before rolling back up. :)
This absolutely works great. The only addition I would make is to make a solution of water and dandruff shampoo and wet the entire awnining with it - rolling it up and out to get a good coating on it. Then let it dry and roll up. A friend's daughter (more or less) told him about researchers in the tropics coat all their stuff with it and it really keeps the mold and mildew down. It apparently has great mold inhibitors in it and I swear by it. duh1 - still learning.
