Repairing Paint Chips; Cleaning The Wheels; Underbody - Ford 1998 Expedition Owner's Manual

Maintenance and care
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 in Cleaning 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 Car Care
Chemicals 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.
The brushes used in some automatic car washes may damage the finish
on your wheels. Before going to a car wash, find out if the brushes are
abrasive.

Underbody

Flush the complete underside of vehicle frequently. Keep body drain
holes unplugged. Inspect for road damage.
