I have chrome Z06 wheels and two of them have some minor grime and spots on them. Washing them with Zaino wash gets most of it off, but there are a couple tough spots that I cant seem to clean. What is a good a good safe chrome cleaner that I can use to try and get these spots off?

 

Try using a claybar. If that doesnt work, use simple green cold rims. Whatever you do, dont use it on hot rims. Let them cool completely first!

 

Yes, I'd second the above recommendation.

Also, Mother's makes a good chrome polish.

Here are some other metal polishes you might be able to find locally if you shop around: Metal Polishes

Never used the 3M chrome polish, but I'd bet it works good too.
