To those of you who have or have had RV's with the aluminum lap siding, what products and methods did you use to keep the siding looking well cared for?
I use Spic-n-Span on the roof, and Zipwax on the sides once or twice a year. Reliable RV cleaner on the black streaks. After 6 years, the side that always faces the sun is starting to chalk and dull a little, so this year I'm going to try something to bring back the shine.
When washing, don't forget the gutters. That's where a lot of the black streaks come from.
