What causes premature oxidation on painted/cc'd surfaces?

I was doing a Quick Detail for a new customer today and on top of the swirl marks, I noticed that when I dried the rims off (used a light dilution of APC to clean them), the surface was chalky and dull. I have used this APC on many different kinds of wheels in the same fashion so I knew it wasn't that.



I know he got the car washed every week since he got it. Where at? No idea, but by the signs of the swirls, I know they more or less half a$$ed it. It was an Audi S4 and they are known for relatively strong clearcoats.



My thoughts are they used some sort of strong wheel cleaner everytime. Any specific info on what type would do this would be greatly appreciated. FWIW, I plan on using it to my advantage for future selling as well as personal knowledge.





Thanks in advance.
 
EO A to Z will do the same thing to a hot wheel. I saw this first hand and it didn't take long (about 2 minutes). My neighbor thought he was being a smart guy and grabbed my bottle of A to Z to clean his wheels on his Honda and sprayed it on while the wheel was hot. He said it dried pretty quick and then he rinsed it off without any agitation. Good for him he only did one wheel but the damage was done and obvious! He came and told me what he did but it was too late then.
 
Eagle's A2Z actually state "...allow to soak for 15-30 seconds..."

I've seen them stip a cold wheel surface, on a 'hot' surface I dread to think

On some of those acid based wheel cleaners, it only takes one time. I always advise my customers to only use car wash soap and water on their wheels.
