same here, no issues on my .1 GTS CLs. Been using Sonax for over 3 years on it.

This is what I use after each wash. Adds shine and protection and the CLs always look like new.

I too have used Adams Deep Wheel Cleaner for 2 years without issue. I e-mailed Adams support specifically about the CL and this is their response: "Our wheel cleaner is a PH balanced product with a lot of cleaning agents in it. For your safety, you can use the wheel cleaner non-diluted but, in your scenario, we suggest that you dilute the wheel cleaner 50/50, so half cleaner and half water." I plan to do that going forward.

If possible, use a wheel cleaner that states it's "TUV" approved - see the description below for the P21s wheel cleaner.

http://www.autogeek.net/5litcan.html
Approved by German automakers for cleaning wheels prone to brake dust.

The German TUV is an independent consumer testing agency that can make or break a product based on their recommendations. This group is respected worldwide for their rigorous testing and stringent standards. So when the TUV recommended brake pads made with graphite, German auto manufacturers listened. This is the reason why German-made vehicles produce such an inordinate amount of brake dust.

To remove brake dust and thereby prevent its corrosive effects, a German chemist developed P21S Wheel Cleaners. It didnít take long for top automakers like Mercedes, Porsche, BMW, and Audi, to adopt P21S as their product of choice for cleaning and maintaining their factory alloy wheels.

P21S Wheel Cleaners are not your average cleaners. They safely lift brake dust, road grime, and grease off your wheels without corroding the clear coat on alloy wheels. Many people donít know their wheels even have a clear coat until they have destroyed it with a harsh cleaner. P21S Wheel Cleaners can be used on any type of wheels or wheel coating without fear of corrosion or abrasion.

P21S Wheel Cleaner comes in two formulas: one for moderately soiled wheels and one for heavily soiled wheels. The High Performance Wheel Cleaner is for wheels that are regularly cleaned and have a relatively thin coating of brake dust. This cleaner is probably all you need for typical American and Japanese vehicles. The Special Performance Gel Concentrate is for wheels with a thick coating of brake dust and grime. These may be neglected wheels or German-made wheels that are prone to brake dust.

P21S Wheel Cleaners are easy to use. Just spray on and rinse off with a powerful stream of water. Tough spots may require some agitation with a sponge.

I just noticed this for the first time after having my tires changed at the dealer. Never happened before after 2 years ownership..I admit I let the dealer (for the first time) clean the car because I was lazy and it was winter ..never again. Is this from the torque wrench or a defect in the bolt? I have used 2 different wheel cleaners and never before had this problem.

Don't think its torque wrench as whole nut seems messed up. And it doesn't seem scratched, rather that the finish got chemically damaged. How do the wheels look? Maybe they just scrubbed too hard with a harsh chemical? How do the wheels look? Also do all 4 CLs look the same? Go back to them and have them replace all 4 CL nuts.

The wheels actually looks fine. Yes all 4. I was reading above and apparently the center bolt is anodized aluminum while the wheel is painted, so the bolt is susceptible to this type of damage. I'm going to take it back when they open. Will report back.

I have my 911.2 GTS coming next week with CLs... Does anyone here use Optimum FerreX for cleaning your wheels? This is what my detailer and I use to clean wheels (Works really well), might have to find something else if this causes the finish to come off. Plus when I get the car coated with gtechniq crystal serum, the wheels also get coated

Neither. It was from the industrial grade, acidic wheel cleaner the dealer used. Have them replace if they truly didnít look like that before.
