Ops on how to clean painted wheels

 

dude nice rig! man I have XD monsters and for cleaning i just use the same wash mitt i use on my truck. here the thing i cant figure out how to do well, the inside rim.... mine get nasty and i cant figure out how to keep them clean....

 

Nice truck! I just don't want to tear the wheels up by using a bad chemical on them.
This why I need to clean them!
