Clean a polished aluminum finish using mild dish soap and water; dry with a soft cloth. The appearance of polished wheels (that are not clear coated) will diminish over time unless they receive additional care and maintenance. After cleaning, apply a coat of soft, non-abrasive cream wax or wheel seal. A specially formulated custom wheel polish and wheel seal is recommended to return shine to oxidized wheels. The finish on polished aluminum wheels is not covered under any warranty.
