Went to Walmart last week looking for A2Z wheel cleaner...haven't been able to find it anywhere..everyone's out of stock...saw 2001 foaming wheel cleaner....green bottle...cheap.. $2.44 for the large bottle...safe for all wheels. Tried it out Sunday morning...works pretty good..needs a little agitation...not much, but results are quite good. I liked it...and at less than half the price!
