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

line. Observe the application instructions on the products.
Remove particles such as bird droppings, tree sap, insect remains, tar
spots, road salt and industrial fallout immediately.
Cleaning the wheels
Wash with the same detergent as the body of your vehicle. Do not use
acid-based or alcohol-based wheel cleaners, steel wool, fuel or strong
detergents. Never use abrasives that will damage the finish of special
wheel surfaces. Use a tar remover to remove grease and tar.
Cleaning the engine
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
²Take care when using a power washer to clean the engine. The high
pressure fluid could penetrate the sealed parts and cause damage.
²Do not spray with cold water to avoid cracking the engine block or
other engine components.
Maintenance and care
138

²Cover the highlighted areas to prevent water damage when cleaning
the engine.
²Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
Cleaning the engine
Cover the underhood electrical connections and terminals of your vehicle
when cleaning the engine compartment. Avoid spraying or splashing
cleaning solvents or detergent solutions on the terminals and
connections. After the cleaning is completed and with the engine not
running, remove the protective cleaning coverings. Exposing electrical
connections and terminals to cleaning solvents and detergent solutions
over a period of time can corrode them and result in electrical system
damage and malfunctions.
Cleaning plastic exterior parts
Use vinyl cleaner for routine cleaning. Clean with a tar remover if
necessary. Do not clean plastic parts with thinners, solvents or
petroleum-based cleaners.
Cleaning the exterior lamps
Wash with the same detergent as the exterior of your vehicle. Use glass
cleaner or tar remover if necessary.
To avoid scratching the lamps, do not use a dry paper towel, chemical
solvents or abrasive cleaners.
Cleaning the wiper blades and windshield
If the wiper blades do not wipe properly, clean the wiper blade rubber
element with undiluted windshield washer solution or a mild detergent.
To avoid damaging the blades, do not use fuel, kerosene, paint thinner or
other solvents.
If the wiper still does not wipe properly, this could be caused by
substances on the windshield such as tree sap and some hot wax
treatments used by commercial car washes. Clean the outside of the
windshield with a non-abrasive cleanser such as the non-abrasive
Bon-Amitpowder. Rinse thoroughly with clean water.Do notuse
abrasive cleansers on glass as they may cause scratches. The windshield
is clean if beads do not form when you rinse it with water. The
windshield and wiper blades should be cleaned on a regular basis, and
blades or rubber elements replaced when worn.
Maintenance and care
139

Cleaning the instrument panel
Clean with a damp cloth, then dry with a dry cloth.
Avoid cleaner or polish that increases the gloss of the upper portion of
the instrument panel. The dull finish in this area helps protect the driver
from undesirable windshield reflection.
Cleaning the interior fabric
Remove dust and loose dirt with a whisk broom or a vacuum cleaner.
Remove fresh spots immediately. Follow the directions that come with
the cleaner.
Cleaning and maintaining the safety belts
Clean the safety belts with a mild soap solution recommended for
cleaning upholstery or carpets. Do not bleach or dye the belts, because
these actions may weaken the belt webbing.
Check the safety belt system periodically to make sure there are no
nicks, wear or cuts. If your vehicle has been involved in an accident,
refer to theSafety belt maintenancesection in theSeating and safety
restraintschapter.
Underbody
Flush the complete underside of vehicle frequently. Keep body drain
holes unplugged. Inspect for road damage.
Cleaning leather seats (if equipped)
For routine cleaning, wipe the surface with a soft, damp cloth. For more
thorough cleaning, wipe the surface with a mild soap.
Maintenance and care
140

If the leather cannot be completely cleaned using a mild soap and water
solution, the leather may be cleaned using a commercially available
cleaning product ªTanners Preserve Leather Cleanerº and a 3M ªType T'
scrubbing pad by using the following steps;
The type of scrubbing pad is very critical because the common 3M
ªScotch Briteº green pad is too aggressive and will damage the
leather surface
²Spray a small amount of the leather cleaner on the pad and rub the
area to be cleaned with the pad using a circular motion. Only clean 1/4
of the area at a time. For heavily soiled areas, spray the cleaner
directly onto the leather (two squirts should be adequate) and rub
with the pad. Repeat if necessary.
²Use a soft, damp cloth to remove the loosened dirt and foam.
²Dry with a soft cloth.
Do not use household cleaners, glass cleaner, alcohol solutions or
cleaner intended for vinyl, rubber or plastics. These products can
damage the leather.
In some instances, color or dye transfer can occur when wet
clothing (wool, denim, leathers or other non-colorfast garments)
comes in contact with leather upholstery. If this occurs, the
leather should be cleaned immediately to avoid permanent
staining.
ªTanners Preserve Leather Cleanerº (product number AS-300) is
available from ªFirst Brandsº by calling 1±800±726±1001. This product
may also be available at many local automotive after market stores.
