I still don't understand why its 2014 and with all the pH neutral iron attacking wheel cleaners on the market why wheel acids are still being used. Sure it is sometimes needed in extremely hammered situations for a detail (as in one of your customers hasn't cleaned their car in a wheel and a year of brake dust might need breaking up), but even then, acid cleaners such as Meg's Wheel Brightener etc advertise that they are not for use on non-clear coated wheels.

Always start with safest method first (soap + water, with a little APC mixed in if you need some extra bite), then try a wheel cleaner like Sonax FE+ if needed. Step up to a wheel acid if they are extremely terrible.

Afterwards you should be able to seal the wheels with paint sealant (non matte finishes) and clean with soap and water for maintenance.
