You will enjoy using P21S wheel gel, as it has a "programmable" dwell time. It will foam when agitated. I found it to be a good tire cleaner also. Remember to flush the wheel and tire surfaces very well with a strong stream of water. Afterwards, applying a sealant will add up to easier future wheel cleaning sessions.
I have found that P21S' cousin, S100 Wheel Cleaner gel, works just as well at half the cost!
[Mark...If you using this for your Corvette you will notice that the wheels' chrome will take on more of the deep, natural, almost bluish appearance indicative of a true chrome finish. I, also remove my wheels twice a year to clean the barrels, use an aluminum polish (Mother's) to bring out the shine on the barrels, and seal them also.]
