Cleaned my wheels first time today at 500 miles. Have PCCB's. Driving included some dirty back roads and driveing in rain. Fastest wheel clean up I have ever experienced thanks to no brake dust grunge. Not sure that is worth $9 k but it was almost fun and took no time. My wheels are painted silver. I am doing nothing more than a periodic wash. I have the Griots wheel cleaner and tools and they are great. I am now a big PCCB fan.

 

Had Cquart's done on face and with PCCB's it mostly a rinse off.

 

I can't stand the smell of this product! When it was initially shipped by Amazon, the odor of the product was profound - even without an apparent leak. I used it once and agree that it is effective. However, I didn't find it to be more effective than other conventional products. Because the smell was so off-putting to me, I double zip lock bagged it and tossed it after a single use.
