Whats the best out there to get? My sisters wheels on the Z28 she got looked like the guy hadn't cleaned them in years and he did tell me they where chrome when I told him I liked the black wheels on the black car. So what can I use to save them?
It is probably just baked on brake dust. You might want to try Meguiars Hot Rims wheel cleaner. You should be able to find it at just about any auto parts store. They also make a product called "Extra" all purpose cleaner which would also work well.
I usually use those chrome polishing swabs from Eagle1 that come in a can. Can't remember the exact name but they work really well on my rims and are pretty cheap.
