Appearance Care
Aluminum Wheel Maintenance
Refer to Saf ety Precautions on page 131 .
Aluminum may corrode from contact with dirt, mud, or road salt. Clean
the wheels after riding through any of these substances. Use a wet
sponge and mild detergent. Avoid stiff brushes, steel wool, or cleaners
containing abrasives or chemical compounds.
After washing, rinse with plenty of water and dry with a clean cloth.
Then apply a mild, commercially-available spray cleaner/polish or wax.
For stained or dull-looking wheels, use a quality chrome/aluminum
polish to restore the finish.
