Rust on chrome rims?
What's the best way to remove black rust from the chrome wheels?
Re: Rust on chrome rims?
The wheels are aluminum with chrome/nickle plating - Are you sure you don't have brake pad dust buildup ??? A commercial "wheel cleaner" spray and elbow grease - but don't scratch the chrome.
Surf through www.autogeek.net - they have all sorts of stuff.
