My sable is a 2000 with the 5 spoke "chromtec" rims. This will be its 4th winter, and the rims look as good as new ones that I see. Right now they are covered with salt, cinders, and other road crap that it picked up in the winter. It is impossible to keep my car clean (black) during winter, so I just really don't try too hard, just a quick run through the touchless car wash every now and again to get the extra salt off. I just prep the car in the fall for a long harsh winter. When spring comes, it will get a full detail.
