I have OZ Racing / Ultraleggerra Silvers. There seems to be something that stained them. Maybe when I had my brake job done and the lube that they used ended up spraying itself over the wheels, I don't really know. I have tried washing them but they are definitely stained. I know that chrome cleaner will not work because these are a painted wheel. Any help would be appreciated.

 

Try Super Clean. http://www.superclean.com/index.php This stuff works. You spray it on your wheel and let it sit for about 30 secs and start scrubbing and it will take just about every thing.

 

Brake fluid is the worst thing you can get on paint. If that's what you have then I doubt anything will take it off and the wheel will have to be refinished .... but I hope not!!

You might try claying them > http://www.zainostore.com/Merchant2/...duct_Code=Z-18
