Where can I get wheels cleaned up?

I have a set of five powder-coated SSR GT-1 spoke wheels that are literally CAKED with brake dust, oil, and track dirt, plus they are scratched up after a season of road racing. Is there any place nearby that can get the brake dust off and clean up the powder coating? They look like crap now and they were so beautiful once.

degreaser, wheel cleaner, or brake cleaner (if the others dont work) plus a car wash. To be repowder coated they need to be sandblasted, to be sandblasted they need to be cleaned. Detail shops clean wheels atached to cars, but idk about wheels that are not.
