•Never wash or rinse any ignition coil, spark plug wire or spark plug
well, or the area in and around these locations.
PLASTIC (NON-PAINTED) EXTERIOR PARTS
Use only approved products to clean plastic parts. These products are
available from your authorized dealer.
•For routine cleaning, use Motorcraft Detail Wash (ZC-3-A).
•If tar or grease spots are present, use Motorcraft Bug and Tar
Remover (ZC-42).
WINDOWS AND WIPER BLADES
The windshield, rear and side windows and the wiper blades should be
cleaned regularly. If the wipers do not wipe properly, substances on the
vehicle’s glass or the wiper blades may be the cause. These may include
hot wax treatments used by commercial car washes, water repellent
coatings, tree sap, or other organic contamination; these contaminants
may cause squeaking or chatter noise from the blades, and streaking and
smearing of the windshield. To clean these items, follow these tips:
•The windshield, rear windows and side windows may be cleaned with
a non-abrasive cleaner such as Motorcraft Ultra-Clear Spray Glass
Cleaner (ZC-23), available from your authorized dealer.
•The wiper blades can be cleaned with isopropyl (rubbing) alcohol or
Motorcraft Premium Windshield Washer Concentrate (ZC-32-A),
available from your authorized dealer. This washer fluid contains
special solution in addition to alcohol which helps to remove the hot
wax deposited on the wiper blade and windshield from automated car
wash facilities. Be sure to replace wiper blades when they appear
worn or do not function properly.
•Do not use abrasives, as they may cause scratches.
•Do not use fuel, kerosene, or paint thinner to clean any parts.
If you cannot remove those streaks after cleaning with the glass cleaner
or if the wipers chatter and move in a jerky motion, clean the outer
surface of the windshield and the wiper blades using a sponge or soft
cloth with a neutral detergent or mild-abrasive cleaning solution. After
cleaning, rinse the windshield and wiper blades with clean water. The
windshield is clean if beads do not form when you rinse the windshield
with water.
Do not use sharp objects, such as a razor blade, to clean the
inside of the rear window or to remove decals, as it may cause
damage to the rear window defroster’s heated grid lines.
