Wheel cleaning, Non Acid vs. Acid, whats the diff?

[hunter 408]

Wondering what the difference in Non Acid vs. Acid wheels cleaners is. How do the different acidity levels affect the clean and the wheel, good or bad?

Is a sealant type of product required when using and acid based wheel cleaner?

I've always used non acid to date.

Acid based is not a good idea for painted wheels. Imo although it will cut off old baked on brake dust it will also strip away the paint. Wheel sealant is a good idea to make cleaning wheels easier.
