Our 2011 Crossroads Zinger is starting to get dingy from years of towing, highway miles, and storage of the winter. Even with washing it a couple of times a year, it's still starting to get some of those gray/black streaks on it in areas.....and no amount of washing or scrubbing takes it off. It's especially bad on the front.
The only think I've found that works is buffing/polishing compound....but I'm not sure I want to waste an entire weekend buffing the whole trailer down.
Are there any cleaners/sprays out there that work to brighten up dingy white travel trailers?
Forgot to mention this, couple weeks ago I was at Lowe's and in the power wash section they had a cleaner called 30 second cleaner, white bottle, attach to garden hose, get siding wet, then turn valve to soap, spray lightly and then in 30-50 seconds, use a brush gently, it worked like gang busters on my siding. no streaks and clean as a like new. Try it on the RV.
Purple Power will clean the stink of a cows behind. spray it on, let is soak a bit but don't let it dry, wash off with normal car wash type soaps and a soft vehicle brush. My kids call it "Purple Jesus" because it has such "cleansing power".
