CLEANING AND CARING FOR YOUR VEHICLE
Refer to the ªCustomer Assistance Guideº for a list of Ford-approved
cleaners, polishes and waxes.
Washing your vehicle
Wash your vehicle regularly with
cold or lukewarm water. Never use
strong detergents or soap. If your
vehicle is particularly dirty, use a
quality car wash detergent. Always
use a clean sponge, washing glove
or similar device and plenty of water
for best results. To avoid spots,
avoid washing when the hood is still
warm, immediately after or during
exposure to strong sunlight.
During winter months, it is especially important to wash the vehicle on a
regular basis. Large quantities of dirt and road salt are difficult to
remove and also cause damage to the vehicle.
Remove any exterior accessories, such as antennas, before entering a car
wash. If you have wax applied to the vehicle at a commercial car wash, it
is recommended that you clean the wiper blades and windshield as
described inCleaning the wiper blades and windshield.
After washing, apply the brakes several times to dry them.
Waxing your vehicle
Wax when water stops beading on the surface. This could be every three
or four months, depending on operating conditions.
Use only carnauba or synthetic-based waxes. Use cleaning fluid or
alcohol with a clean cloth to remove any bugs and tar before waxing
vehicle. Use tar remover to remove any tar spots.
Avoid getting wax on the windshield. If you have wax applied at a
commercial car wash, it is recommended that you clean the wiper blades
and windshield as described inCleaning the wiper blades and
windshield.
Repairing paint chips
Minor scratches or paint damage from road debris may be repaired with
touch-up paint, repair foil or aerosol paint spray from the Ford accessory
