I have found that once the wheels are clean using a non-wax "wax" gives better results.
It seems that carnauba wax will melt and evaporate quickly while the synthetic waxes last much longer.
Also, most wheels are covered with a clear coat. Taking care of the clear coat is the real job. Using a metal polish is great if your wheels are exposed metal (aluminum). Typically Mercedes wheels clear-coated to prevent corrosion.
My 2 cents,
