Wheel Cleaner "strength"

[MMarky]

For me, like many in this forum, my wheels are sealed and wash up nicely using just regular wash water.

However, as you know, most folks don't maintain their cars like we do. Once in a while, I get to clean one of those dirty buggers. That's why I want to learn about wheel cleaners and now "strong" they are.

Please make a list of the ones you have used, in order of strength. aka, least powerful/acidic to "strongest."

Thanks,
MMarky
