I have carbon ceramics on my car. What you said above is the actual truth. They are a bit more stout than you would think. If they werent they would not be able to sell them to the general public.
The real confusion is that most products will NOT physically damage them, but MOST products will degrade their performance significantly. Specifically its the products with silicone in them. So that includes basically any wipe on, or spray sealant or tire protection.
Regarding cleaning them, you want to be sure you are using a straight cleaner. PH is not a real issue like most people believe it is regarding these brakes rotors. But its better to be using something of high quality that rinses easily. The only thing I am still unsure of is the iron removing wheel cleaners. Sonax goes out of there way to suggest to avoid spraying FE on the rotor itself.
When it comes to wheel cleaners you really need to consider that when the car is using Carbon Ceramic Brakes the wheels do NOT get dirty (with brake dust). at all ! I mean that literally. They get dirty in the same sense that your lower body panels get dirty. Meaning they clean off easily with soap and water. Even though thats true I still use a wheel cleaner on my wheels.
The products I use to clean my wheels with CCB's.
- P21S regular wheel cleaner (the NON gel) - This one works a LOT faster. I find it more powerful as well.
- P21S GEL wheel cleaner
- Blackfire wheel cleaner (
Blackfire Gel Wheel and Tire Cleaner )
You can also use APC's that are natural solvent based
- P21S TAW
- Auto Finesse Citrus Power
The real issue is like mentioned earlier , the protection products especially spray tire dressings or wheel sealants. The Carbon rotors have very deep cracks in them uniformly throughout. making the material extremely porous and able to expand and contract a significant amount. So anything you get on the surface of the rotor will be pulled deeply into the material and unlike standard iron rotors you will NOT be burning off whatever lands on the surface.
- Just a quick fact and something to think about regarding the porousness of carbon ceramic brake rotors (and why it is not good to get foreign chemicals on the rotor). But do you know how to tell if your Carbon rotors are worn out and need replacement (without googling the answer !

) ? You probably thinking they will get thin and once they are thin beyond a certain point they are worn out, right ? well no. They actually become lighter. The thickness remains very close to the same. Only the VERY outer edge is worn off over time. The internal material is actually burned off inside them each time they reach certain temperatures. Making them lighter and lighter everytime that specific temp is reached. That is another significant reason that these brakes will easily last the life of a street driven car. Think of it like an internal fiber is being burned each time enough heat is introduced.
If you do get silicone on the rotors there is pretty much no turning back so thats why its so important to be careful to avoid it. I have seen rotors that have been damaged. Interestingly enough they turn a slight different color. Mostly they get a greenish tint to them but I have also seen the tint in blue as well. The actual reason you rarely see customers complain about the problem is because these brakes are now being installed on street cars. So if you degrade the performance of the braking system on a street car who the heck is going to notice the difference ?? These braking systems are never used to there intended capacity on the street. A typical drive will not even allow them to reach optimal running temperature. So how on earth will you notice if the performance degraded by even such a large number like 25% ? you wont. so thats why you do not see more claims of damaged rotors. Thats just my theory.
