thank you for the update. i know i use the "black streak remover" but it doesnt seem to do a great job. maybe i waiting too long before trying to clean them off. maybe using the stuff you did would be good for once or twice a year with the less corrosive cleaners in between. time will tell i guess.
That black streak remover worked but I had to but some muscle into it. Im a believer in this stuff. It even cleaned the stains off around the aluminum frame of the door.
It didn't affect the stickers or caulking any. I used regular soap for the roof washing...
Best way I found to stop the black streaks is to remove the main cause, scrub the roof.
Before the camper goes back in the shop after each use, I wash it completely - including the roof. I still get those black streaks. This past weekend had one day of rain, and I had black streaks to scrub when I got home.
