uuCleaning uExterior Care
Maintenance
If you get gasoline, oil, engine coolant, or battery fluid on resi n coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. When necessary, as early as possible use a sponge and mild detergent
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals
(including some commercial wheel cleaners).
These can damage the protective finish on aluminum alloy wheels, resulting in
corrosion. Depending on the type of finish, the wheels also may lose their luster or
appear burnished. To avoid water stains, wi pe the wheels dry with a cloth while they
are still wet.
