I'll give you a run down of our whee cleaners.
Aluminum Wash and Cleaner - This was designed for polished aluminum wheels where oxidation can occur from other wheel cleaners. It is pH neutral and is very mild. It is safe for any wheels, however because of the very mild cleaning properties, cleaning grime and heavy brake dust will take some agitation.
A2Z All Wheel Cleaner - This is now available in an orange bottle. The new orange bottle is an alkaline based formula. Designed for use on all wheels. It used to be in a black bottle which is an acid based formula. For most grime and brake dust it will clean quickly, however for heavy build ups it will require agitation.
Chrome and Wire Wheel Cleaner - Designed for chrome plated wheels. This is a stonger formula and should only be used on chrome wheels or spokes wheels (not motorcycles or gold wheels). Only use on true chrome plated, not any of the new chrome look finishes.
Etching Mag Cleaner - Our strongest cleaner and should only be used on true "As Cast" alloy wheels. These are wheel brands such as Western and I do not believe there is any current as cast wheels, these are usually early 80's wheels and found on llarger trucks.
In any case, be sure the wheels are clean when using. Sorry guys for the long list, not advertising, just giving a run down on what cleaners are for what type of wheels.
