Cleaning black streaks
We have an aluminum siding travel trailer. We can't get rid of the black streaks. We have tried the LA Awesome cleaner with a pressure sprayer and had no luck. Any suggestions??

I have used Reliable RV cleaner quite a bit over the years to great effect. It ain't cheap but a little goes a long way. Wipes them right off. You should wax after but you don't have to.
