I take it that the rims aren't clear coated or the clear has come off, that being said try some Never Dull. It comes in a silver can and has pre-moistened material that you just rip off and wipe on your rims or metal surfaces. You'll notice it start to turn black but that ok, its working. Let me know how that works for you. Another little hint for you, after your done with the Never Dull spray glass cleaner on them and wipe off, it seems to "bring out" more shine
