Get a bottle of Mothers wheel cleaner in the YELLOW bottle. Spray on and hose off. It is remarkable. Best I've found so far. I even spray it through the openings to the back of the rims. When hosed off, you can see the full width of these wheels. NICE detail.

If needed, a little wheel polish will make quick work of any left over residue. If wheels are kept waxed, then the cleaning is much easier. For cleaning and wax I use the Treatment cleaner and wax. I am very fond of these two products.
