Wheel Gunk- PIX
Hey Gang,
Every time I wash my car, when driven immediately the centrifugal force is depositing this strange gunk on my wheels, both inside the barrels and on the outside rim area. What is this crap? I had just used a wheel brush to clean the insides of the barrels. I do use a pressure washer am I driving grease out of the bearings God forbid??? :bang head:
Thanks!!

It's mostly in the front. I suspect that it is a mix of brake dust and rust mobilized by the water. Kinda greasy though which is strange. Hard to get off.

This also has always bugged me, but I'll admit it's no where near as much gunk as that! As others have stated it's likely a mix of water/brake dust residue coming out of the rotor vanes. My 'solution' has been to roll the car slowly to get full rotation of the wheel (after it's washed but before dried) and this lets this gunk fall out of the rotor vanes into the wheel. Then simply hose it out of the wheel before drying. Effectively no residual gunk!

It's just dirty rusty water from the discs. Happens every time I washed the car.
It's in the vent and cross drill holes.
So now it's either go for a drive after washing and before polishing to clean out the water or wash after a drive when the discs are hot.
Generally though, I find no need to directly spray the discs.

As others have stated the best way to solve is driving the car immediately after washing. This is from flash rust that forms on your rotors after washing. Seems to be worse on the Porsche rotors than my other cars.

As others suggested, use a leaf blower to dry the brakes. You'll still get a light dusting of rust since the surfaces will still be prone to it but it will be far more manageable. Alternative is to not use wheel cleaners or water when cleaning wheels and just stay on top of it with quick detailer and old microfibers. I've been doing this for the past four years and the wheels still look perfect with exception to a few rock chips.

Not pulling your leg. I never used the blower on the Range Rover but with the 911 I use it after every wash and it almost eliminates the problem. I figure compressed air would work too but I just use the blower.
