FORD 2001 Crown Victoria - Manual (Page 217)

Cleaning the exterior lamps
Wash with the same detergent as the exterior of your vehicle. If
necessary, use a tar remover such as Ford Extra Strength Tar and Road
Oil Remover (B7A-19520–AA).
To avoid scratching the lamps, do not use a dry paper towel, chemical
solvents or abrasive cleaners.
Cleaning the windshield, wiper blades and rear window
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 or rear window such as tree sap and some
hot wax treatments used by commercial car washes. Clean the outside of
the windshield or rear window with a non-abrasive cleaner such as Ford
Ultra-Clear Spray Glass Cleaner, (E4AZ-19C507–AA), available from your
Ford Dealer. Do not use abrasive cleansers on glass as they may cause
scratches. The windshield or rear window is clean if beads do not form
when you rinse it with water. The windshield, rear window and wiper
blades should be cleaned on a regular basis, and blades or rubber
elements replaced when worn.
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 with cold water to avoid cracking the engine block or
other engine components.
• Never apply anything to the drive belt (including belt dressing).
