i have no idea about your rims, but last week i went looking for some wheel cleaner and most of them say they only work on certain surfaces and i had no idea what mine was either. I ended up finding some Turtle Wax wheel cleaner which says it can work on any surface (about $18 from supercheap auto) ive only used it once so far but seemed to work good.. i think it was this one http://www.autobarn.net/all-wheel-and-tire-cleaner.html
