Periodically cleaning of your wheels is necessary to maintain a high luster, especially 24K gold plated wheels these require extra care. Always clean using a mild dish soap and water such as Dawn and a clean microfiber cloth, to clean inside the hub and spokes use a soft horse hair paint brush. NEVER use any harsh cleaning compounds or waxes as the are abrasive and will remove the gold plating. During storage spray a light coating of WD40 on the wheels to prevent rusting.
