I forget where I picked this up I think it was good sam or rv net but it matches a lot of the other post I have read on cleaning your awning.
The "Awning Tips & Tricks" brochure that came with my unit suggests
a mixture of 1/4 cup of dish soap, 1/4 cup of bleach and 5 gallons of
water. It suggests soaping the open awning with the mixture, then roll
it up for 5 minutes while you clean the bottom up next to the trailer.
Then unroll and rinse.
We use Meguires marine and rv wax.Our 5er sat on the lot for quite a while so we used Meguires high gloss polish before waxing as it is supposed to restore oils into the gel coat finish.I dont know if its necessary or not but it sure looked pretty when we were done.Meguires also makes an oxidation remover if it looks that bad.Spic and Span works well for us in cleaning.be sure to clean your slide seals too cause they are probably a mess.WD 40 will cut the gooey stuff,next time We are going to try greased lightning after the wd to see if it will get them any better.they take a lot of scrubbing it took a long time just on seals and We are still not happy with the results.
ps. wear lots of sunscreen you are gonna be out there a while
