You might want to distinguish between cleaning and polishing.
"Cleaning" refers to the process of removing dirt from rims that are already smooth and shiny. "Polishing" usually refers to the process of using something abrasive (tools and/or materials) to wear down (smooth down) a wheel that has a different finish on it, or that has been damaged, to make the surface of the wheel smooth and shiny.
If you are buying wheels that are already chrome, it sounds like you're asking about a wheel cleaner, not a polish.
I'm not trying to be picky, just trying to understand your question and help get you the best information you're looking for...
