Be careful with ammonia-based cleaners if you have tinted windows in the front! I would just by a can of Invisible Glass non-ammonia cleaner.
Also if you want to be cheap and all environmental and stuff by reusing available resources, just use wadded up newspaper. It really does work great. It's removed film I couldn't completely remove otherwise.
Maybe tomorrow's 2 feet of snow will remove some of the winter camo. I just used "Canoclear", Canon's microfiber lens cleaner on the NAV screen. It did a good job of removing the fingerprints with little effort.
They just built a new car wash near me,$3 dollar touchless or they have 50 cent Tuesdays do it yourself. I'm in heaven!!It's hard to keep your car clean here,Hopefully the snow will end soon.
