Aluminum Wheels
If your Geo has these, don’t use chrome
polish on them. Use wax after you clean
them. Also, don’t use abrasive cleaners or cleaning brushes on them
- you
could damage the protective coating.
If you have aluminum wheels,
don’t use an automatic car wa:
that has
hard silicon carbide
cleaning brushes. These brushes
can take off the protective coatinl
Weatherstrips
These are places where glass or metal
meets rubber. Silicone grease there will
make them last longer, seal better, and
not squeak. Apply silicone grease with a
clean cloth at least every six months.
Sheet Metal Damage
If your vehicle is damaged and requires
sheet metal repair or replacement, make
sure the body repair shop applies
anti-corrosion material to the parts
repaired or replaced to restore corrosion
protection.
Foreign Material
Calcium chloride and other salts, ice
melting agents, road oil and tar, tree
sap, bird droppings, chemicals from
industrial chimneys, and other foreign
matter can damage your vehicle’s finish
if they remain on painted surfaces. Use
cleaners
that are marked safe for painted
surfaces for these stains.
