Is their a really easy way to clean them....sure....dont clean them at all that's really easy....just kidding!!!
I clean my front and rear regulary, I spray either brake dust cleaner or the hondabrite stuff on my rims, let it soak for a minute then have at it with a detail brush made to clean wheels. Scrub scrub scrub and then rinse all the dirt away and there ya go, clean as a whistle.
Rear wheel, same thing as above but I lye down on my side with my head turned up towards the rear fender and scrubbing away with that brush I just used on the front rims. Rinse all the dirt away and you're golden.
The front wheel is easy to be polished with mothers aluminum polish AS LONG AS YOU KEEP UP W/THE CLEANING AND POLISHING ON A REGULAR BASIS. If I keep up w/the polishing bit, I can polish the front wheel in less a half hour, it comes out looking as close to chrome as it can be. I get many comments on my front wheel because I do keep up with it. Good Luck, Brian
