Wheel cleaning...

Depends on which wheels, the aftermarket Racing Sparco's have to be cleaned on the inside everytime or the job will not look finished at all. I took a 1" dowel rod and planned down flats on opposite sides of each other (to allow me to get between the calipers and wheel) then wrap a towell around it and fish it between the spokes back to the inside lip.

On the stock Mach1 wheels I use the same method but can't get the middle area behind the wide spokes. You can't see it but everytime I have the wheels off I clean that area up too.
 
what a pain! But, yeah I've done it. Road tar and brake dust just won't come off without taking the wheels off. I do this about once a year. And I wax them too.
