It's spring...and I'm cleaning EVERYTHING! lol The trailer is next on the list... Borrowed a friends powerwasher and now need some advice on a good soap/cleaner for an all aluminum (painted white) trailer w/ chrome accents. It's only a year old, so it's not too horrible. Just has black streaks and recent caked mud and some nasty looking grime stuff from sitting out all winter. Advice pleasee!!!

Also..should I wax it?? It's out 24/7 in direct sun...I want to keep it looking NEW. If so, what's a good wax? Thank you!!
