Sun Visor Sticker
Try this 3 step procedure:
1. apply heat with a hair dryer in the low setting and slowly peel off that ugly sticker as others have suggested;
2. the residual adhesive left behind can be removed with some mineral spirits applied with a soft, clean cloth;
3. finish off by using some foam carpet cleaner and dry with another soft, clean cloth.
You could just paint over the damn things but that's not really advised -at least by me.
