Cleaning tires???
Another vote for Westley's here!
Westley's is highly alkaline - it's like using Drano. That's why you gotta try to keep it off the wheels and DEFINITELY keep it off the paint. It does a heck of a job on the tires though. I would not spray it on the tires without making sure the wheel and whole area is wet, the more dilute it is, the less damage it's going to do.
I've *heard* Westley's can cause wheel staining, but never experienced it myself in many years using it on all kinds of wheels - chrome, polished, painted, alloy, steel, aluminum, etc. Normally I spray each wheel and tire down with the hose to blast away all the loose stuff then use Westley's and a scrub brush then rinse the wheel and tire very well.
I use the same Griot's rubber cleaner or Meguiar's APC. I just recently bought some of Griot's Tire Rejuvenator, it works pretty well. It turns the tires a fresh black look, but you can't use on white letters or white walls, it is a black paste. Only used once so far and liked the results, but we will see how long it lasts
Do you really NEED to clean your tires with acid and salt?
With the exception of whitewalls and white lettering I don't use Westleys once I learnt better.

I use westleys bleach white. Does a good job, for the white letters on the tires I use brillo pads. Works for me.
