I've been trying to get the brake dust of my rims and everything I do doesn't seem to work. Anyone know an easy way to get the brake dust off? Any suggestions would help.

Also I know this is a newb question but My tire size is 205/40/16..... Whats the maximum size rims that can fit that? 16 inch?
Thanks

 

brake clean. and clean em every day so it doesnt stick.
