We take ours to a coin-operated RV wash at a local RV park. It usually takes about $4-$5 in quarters. It's like the truck washes you see around. They have an elevated platform on each side so you can go up the steps and wash the roof. It has a spray wax setting and also the foam soap brushes. I start by cleaning off the black streaks with some stuff called Amazing. We take it there twice a year. Also, once a year, I wax my decals with NuFinish.
