I have canvas awnings that have mildew stains from being rolled up during winter. They are black. Any tips on cleaning solutions . methods that would work to clean them while "up" on the windows. Cannot use bleach due to the color fade issue.
imho:
Being aired out, and in the sun might help get rid of any further damaged caused by mildew.
As for cleaning, might want to get an estimate for a professional service to do the work. Might be cheaper, time and money, than trying some DIY solution.
