After oldest son hand scrubbed the roof and washed the camper last week, I decided to tackle the filty awning. Mixed a solution of bleach, SuperClean and Awesome and sprayed it on the top and bottome, rolled it up for 30 minutes, unrolled it and scrubbed it, rinsed it and re-applied the solution again to both sides, rolled it up for another 30 minutes, unrolled, scrubbed and rinsed. Looks good except right at the camper in the white that the the dumbo's that decided to put white in that area. It still has a shadow of discoloring that evidently will not come out. Been this way on all our awnings since 1976. One would think the awning mfgrs don't have a clue as to this problem or they would change. DUMB DESIGN!
Anyway, awning is drying and I'll stow it before the rains come this afternoon. Time to get out the mower and start mowing the 1.48 acres of weeds and the 20 sq. ft of grass. Oh and break up some rocks with the new blades.
