You can remove the anodizing using oven cleaner. But getting it out of all the nooks and crannies around the spokes and eyelets so it won't continue to eat away at the aluminium underneath will be a trick. And when the anodizing is removed in this way the underlaying aluminium will require some polishing or sanding to produce the sort of look you're after since the oven cleaner leaves the surface looking like hell. And again to get a nice consistent finish working around the spokes and eyelets will be a royal pain.

Frankly this is one of those times where it's best to just lay down until the feeling goes away. If you really must have silver rims then swap your wheels with someone that has similar quality wheels that wants black rims.
