This isn't directly related to track activities, but I'm stumped and the search feature hasn't been any help.

A couple of week ago I installed a set of PFC-99 pads in the front of my C5Z daily driver with OEM wheels. The wheels are gray and don't show brake dust much, but when I went to wash the car today, the dust deposits would not come off the wheels.

The deposits look like rust and defied all the cleaners and solvents in my garage.

The question is:

WHAT DO YOU GUYS USE TO CLEAN THESE DEPOSITS OFF, SHORT OF A PNEUMATIC CHISEL?

Thanks,

sounds crazy, but I have had good luck with PB blaster (the penetrating oil) and a no scratch, scotchbrite pad. make sure it's a no scratch pad, because they can be abrasive otherwise. let it soak for a bit, and go for it

I'm watching this thread, too. PFC 01s and old Hawk Blue/Black pads have always done this to me. Sometimes a scrubbing pad from a kitchen sponge gets most of it... sometimes.

yeah, depending on how much of it you have, you may have them on there permanently. for bigger buildup spots, you can try to soak them with wd-40, then gently tap with something like a plastic ice scraper until they start breaking up, then scrub with a wheel cleaner.

i did this when I let hawk blue dust on my street wheels get wet and dry (this is when the pad dust hardens and starts to look like rust). i was able to clean it up some but it damaged the finish underneath and I ended up re-finishing the wheels eventually.

don't use pads that do this for street driving, it only takes one wet/dry cycle to have this happen.

Sure Kleen 600 WILL take it OFF with a soft acid brush. It may not be fun to work with but it will come off. I had it on my GS wheels where it was coming off as thick as potato chips. If you want more info yell. http://www.prosoco.com/Documents/getfile.aspx?filekey={C3D50162-FD4D-4FCA-ACFD-079651FECA72}

Thanks for the replies, guys.

Clay bar takes it off. Probably least invasive method. CLR and other acids will do it too.

This is the reason I switched from Hawk to Carbotech.

i could not get it off with claybar

ArmorAll Aluminum wheel cleaner.

Wet the wheels down

Spray on the ArmorAll wheel cleaner

take a wet rag and wipe the wheels

Hose off

Repeat on the tough areas.


Also a good time to inspect for cracks

Here is a link to my thread. I had the same issue. I have been to the track twice since without issues. It must be something about driving in the rain and letting it harden. The Amorall stuff did the best I could find. I tried brake cleaners, PB Blaster, Sctoch pad. I ended up using the Amorall and a plastic knife to get 98% off. There are still scratches on the wheel and dull spots, but, a small price to pay for good brakes. BTW, I repl my 99s with reg ceramics for street driving. track pads are too expensive and dirty for dd. Just a thought.
