NOTHING is touchless. I like A2Z as well. You shouldn't let the brake dust cake up enough to warrant using a "touchless". The dust will eat/discolor the wheels.

From the Aesthetics how-to Detailers Guide...
"Wheels need a strong cleaner that can break the bond between brake dust, road tar, road grime and the wheel. Wheel cleaners come in two basic formulas: acid cleaners and acid-free cleaners. Acid cleaners are very strong and work without much agitation. Care must be taken not to use acid cleaners on wheels with pitted or chipped surfaces. The acid will migrate into any fissures and accentuate flaking and peeling of surface coatings. Non-acidic cleaners are mild solutions of alkaline solvent. These solutions creep under brake dust to loosen and lift. Non-acidic cleaners require some surface agitation (brush or sponge) but are safer to use than acidic cleaners and will not etch the wheel's finish."
