orange glo works really well. but yeah i just use the meguiar's gold class car shampoo on them also. first make sure the wheels and brakes are cool, Dont spray cold water on hot brakes. i rinse the wheel off, then spray a bunch of orange glo(or car detergent) on it, use a pretty soft nappy sponge, its like furry i guess, then just scrub them really well and rinse then towel dry. keeps them nice and clean
crap i forgot to mention for brake dust, let orange glo just sit on it for awhile then scrub it and rinse
