Right where the water runs from the gutters off the roof, the slide out and I guess mostly everywhere - I have those black streaks that I CAN NOT GET OFF! Been this way since i bought it, and its a 2003 - so who knows when they were cleaned if ever. Anyways, I tried full strength simple green, this strong orange citrus cleaner, streak remover from Wal-Mart (junk) and nothing is getting rid of these. I've been rubbing till I couldn't move my arms and this is a 30 footer! Any ideas? Plans are to sparkle this up so I can wax it before winter. PS- another camper told me mop-n-glow works great as a protectant. ever heard of that?
Thank you!
Thank you!
