Dependant on what form of basis the acid wheel cleaner is will decipher what damage it will potentially cause. Most non acid cleaners are equally as harmfull so whatever you use, its all down to knowing the product and user error. Never heard of acid based wheel cleaners softening laquer so cant comment but within over 16 years of the trade ive never come across it. Acids are corrosive only so if you have a chip or bubble / blister in the laquer it will get under it and cause corrosion, otherwise, carry on. Always ensure you rinse throughly after application and try to steer clear of the brake calipers. Lots are using ironx on wheels atm but you can see its corrosive due to the levels of tarnishing it leaves on the break discs. Im due to try wolfs break duster. Sounds interesting and is very effective.
