PCCB cleaning

[Swine Enthusiast]

I have PCCBs on my 981 GTS and I cannot find a definitive guide on what to clean them with. Ranges from just hot water, to fairy liquid, to any wheel cleaner should be safe.

Had a response from G-Techniq on IG saying they use W5 Citrus All Purpose Cleaner but was curious as to how those with PCCB options clean the wheels, calipers, and discs?

You want to stay away from harsh wheel cleaners, iron removers and certainly no washing up liquid.

A simple jet wash and a good pH neutral car shampoo is all you need. Great thing with carbon ceramics is your wheels should never really be the dirty anyway.

What does washing up liquid do to PCCBs out of interest?

Make them squeaky clean ? And annoys the hell out of the dream crusher because she doesn’t like them in the dishwasher/washing up bowl

Heard you want to stay away from shampoo that has silicon in it?

I seem to recall it contains salts, so it's not good to wash your car with it.

Whichever car shampoo I use for bodywork. (Gtechniq or Meguiar’s)
They are 6 years old but look 6 weeks old.

I jet wash mine after track days but still find that dust needs cleaning out of the holes in the disks ... particularly if it has been a wet then drying day !

Wheel dependant this can sometimes be done without removing the wheels.

Under no circumstances should chemical wheel cleaners be used.

Cleaning the pad dust out of discs and callipers also minimises brake noise on the road ...

P.S. Irrespective of all, after cleaning please expect the discs to need a gentle drying brake before they will work properly ... it's the same on very wet motorways etc.

Looks great! Just been terrified of cocking it up and needing to sell a kidney to replace them

Yeah, always go for a quick drive post wash.

Can snow foam go on PCCBs?

If it’s a neutral shampoo with no additives then yes.

This is well worth a watch, a little geeky but very informative.
