CLEANING THE EXTERIOR

Wash your vehicle regularly with cool or
lukewarm water and a neutral pH
shampoo, we recommend Motorcraft
Detail Wash.

•

Never use strong household detergents
or soap, for example dish washing or
laundry liquid. These products can
discolor and spot painted surfaces.

•

Never wash your vehicle when it is hot
to the touch, or during strong or direct
sunlight.

•

Dry your vehicle with a chamois or soft
terry cloth towel to eliminate water
spotting.

•

Immediately remove fuel spillages, bird
droppings, insect deposits and road tar.
These may cause damage to your
vehicle’s paintwork or trim over time.
We recommend Motorcraft Bug and
Tar Remover.

•

Remove any exterior accessories, for
example antennas, before entering a
car wash.

Note: Suntan lotions and insect repellents
can damage painted surfaces. If these
substances come in contact with your
vehicle, wash the affected area as soon as
possible.

Cleaning the Headlamps

Note: Do not scrape the headlamp lenses
or use abrasives, alcoholic solvents or
chemical solvents to clean them.

Note: Do not wipe the headlamps when
they are dry.

Exterior Chrome Parts

•

Apply a high quality-cleaning product
to bumpers and other chrome parts.
Follow the manufacturer’s instructions.
We recommend Motorcraft Custom
Bright Metal Cleaner.

•

Do not apply the cleaning product to
hot surfaces. Do not leave the cleaning
product on chrome surfaces longer
than the time recommended.

•

Using non-recommended cleaners can
result in severe and permanent
cosmetic damage.

Note: Never use abrasive materials, for
example steel wool or plastic pads as they
can scratch the chrome surface.

Note: Do not use chrome cleaner, metal
cleaner or polish on wheels or wheel covers.

Exterior Plastic Parts

For routine cleaning we recommend
Motorcraft Detail Wash. If tar or grease
spots are present, we recommend
Motorcraft Bug and Tar Remover.

Stripes or Graphics

(If Equipped)

Hand washing your vehicle is preferred
however, pressure washing may be used
under the following conditions:

•

Do not use water pressure higher than
2,000 psi (14,000 kPa).

•

Do not use water hotter than 179°F
(82°C).

•

Use a spray with a 40° wide spray
angle pattern.

•

Keep the nozzle at a 12 in (305 mm)
distance and 90° angle to your
vehicle's surface.

Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.

Underbody

Regularly clean the underside of your
vehicle using water. Keep body and door
drain holes free of debris or foreign
material.

Under Hood

For removing black rubber marks from
under the hood we recommend Motorcraft
Wheel and Tire Cleaner or Motorcraft Bug
and Tar Remover.

WAXING

Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.

When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax.

•

Use a quality wax that does not contain
abrasives.

•

Follow the manufacturer’s instructions
to apply and remove the wax.

•

Apply a small amount of wax in a
back-and-forth motion, not in circles.

•

Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
•

Roof racks.

•

Bumpers.

•

Grained door handles.

•

Side moldings.

•

Mirror housings.

•

Windshield cowl area.

•

Do not apply wax to glass areas.

•

After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.

CLEANING THE ENGINE

Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.

When washing:
•

Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.

•

Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.

•

Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.

•

Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.

•

Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.

•

Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.

CLEANING THE WINDOWS AND
WIPER BLADES

Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.

To clean the windshield and wiper blades:
•

Clean the windshield with a
non-abrasive glass cleaner. When
cleaning the interior of the windshield,
avoid getting any glass cleaner on the
instrument panel or door panels. Wipe
any glass cleaner off these surfaces
immediately.

•

For windshields contaminated with
tree sap, chemicals, wax or bugs, clean
the entire windshield using steel wool
(no greater than 0000 grade) in a
circular motion and rinse with water.

•

Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate.
