Are there any products that can simply be sprayed on and then washed off after a period of time, or MUST I get down and dirty EVERY time to clean my rims? What about water pressure? What PSI could I use without damaging the tires? Could I just use a water compressor to clean my brake rotors and rims? Any help would be much appreciated. FYI It is to clean my stock trans am rims.(if that helps, never know...) The reason I am asking is because I live in the desert where dust is more than prevalent in my surroundings and even the air I breath daily. Rims get dirty VERY fast in my city. Not to mention we have one of the worst maintained city roads in the nation for a metropolis. Seriously, my city is horrible at laying out and maintaining the roads. HORRIBLE...
