Black streaks on camper

[Matt1969]

I need some help with a good cleaner. I have a 2016 aspen trail and it has black Streaks running down the aluminum siding. I've tried all kinds of stuff to get it off with no luck. I can get off with rubbing compound and lots of elbow grease but I don't want to do a 30 ft camper like that. I thiink its mostly soot from camp fires when I had it at hunting camp for a few months. I hoping there a better cleaner that I can use. I've tried goo gone ,goof off,purple degreaser,awesome, bar tenders friend,,several car washes. It's like it's stained into paint. But I can rub it out.

Even though it still will take a lot of rubbing, Mr. Clean Magic Eraser works great.

I've been able to clean them off my camper off with Automotive Krud Cutter (for pressure washers) available at Lowes and a little outdoor bleach. I mix about 1/3 Krud Cutter, 1/4 Outdoor Bleach, and the rest water. Then I spray the area with a 1 gallon sprayer and let it sit for 5-10 minutes and then use an extendable pole with a scrub brush on it and lightly scrub it off and hose it off.

I've had very good results with this stuff, easy to use. It cleaned the step daughter's very dirty aluminum horse trailer like new too (well it is pretty new but was streaked bad)

I just recently cleaned mine with Korkay awning and black streak remover. Worked well. Probably would have been better had I not diluted it.
