dirty white wheels?

[30thANNz28]

i have the factory 30th anniversary white wheels and the front two are turning brown in the corners of the spokes, and i wash it once a week and use wheel cleaner every time...what else would take that out without damaging the wheel

I'd try a mild compound like Megs Scratch X or 3M 30005..
Maybe try somthing like Purble power cleaner. Use on a wet rim and alittle elbow grease. Don't let dry and rise as soon a possible...
