I used to have a show car with chrome wheels....
I used to have a '73 mach I show car with chrome magnum 500s. I destroyed the first set of wheels, because I would chrome polish them every 2-3 weeks. I had learned what to do and what NOT to do by the second set. Take it from someone who learned: don't chrome polish but once a month tops, the chrome polish actually takes some of the chrome with it when you use it. My suggestion would be to wash them regularly, never wiping them with anything more then a wet soapy rag (use hot water if needed). Accompany this by an immediate dry towel buff. Do this regularly enough and nothing will cake or dry onto the wheels. Use the chrome polish, sparingly, when brake dust or other materials will not come off with the hot soapy rag. For a quick shine job and protectant, you can use car polish as well. Because it uses a similar principle: it sticks to the dirt and then dries to form a coating you can wipe off. Good luck and trust me, DON'T USE CHROME POLISH EVERY 2-3 WEEKS! :thumbs:
