I caught wind through the grape vine that a chemist had tested the chemical makeup of Poorboy`s Spray + Rinse Wheel Cleaner and found that it has Hydrofluoric Acid in it.
HFl, for those who don`t know, attacks aluminum and is very strong (health hazard), but works well for those really disgusting wheels.
Can anyone confirm or contest this? Maybe MSDS sheets would help?
