Getting off black streaks

Why do black streaks form so fast and are so hard to get 100% off? Got a 6 month old fiberglass TT and black steaks mostly wash off but you can still see a faint shadow. Even tried a magic eraser. They are on the plastic trim too. Want to keep it looking new but seems very hard to do. Anybody found anything that actually works that's safe on decals?

a clean roof is the best defense to black streaks. . .   As far as removing them, have you ever hand waxed the RV ??  That will remove them, and help prevent them as well.

Good Luck ~ Joe

I've had good luck with WashWax All and keeping the roof clean. I have to say though since I have owned units with full body paint and frameless windows, and gutters, I see fewer black streaks.  I think the old gaskets are the root of a lot of the streaks. I think they degrade over time and the rain washes the residue down. If you notice, most black streaks are below some wall protrusion, like a window, outlet, bin door, awning arm, etc. That's because that's where the black gaskets are. I think paint and a good wax keeps the streaks from sticking/staining and the newer gaskets are less prone to breaking down.

The only thing that worked for us was moving to a location where there were no oil burners and very little big truck traffic. 11 years without black streaks and counting.

My RV was super dirty and I tried everything.  My wife comes out and uses a magic eraser takes everything off made it look Great.  I had tried Meguiars, crud cutter, soap and water but I 100% recomend trying magic erasers they work great. I buy the 50 pack off amazon.

I've used Camco's Black Streak Remover.  Available in the RV Aisle in Walmart or online at Amazon.  Spray and wipe.  The window seals on my previous RV streaked constantly, this was the only product that seemed to work without a lot of elbow grease.
