Most common factors contributing to
vehicle corrosion:
1. The accumulation of moisture-retaining dirt
and debris in body panel sections, cavities,
and other areas.
2. Damage to paint and other protective coat-
ings caused by gravel and stone chips or
minor traffic accidents.
Environmental factors influence the
rate of corrosion:
Moisture
The accumulation of sand, dirt and water on
the underside of the body will accelerate cor-
rosion. Floor sections which have snow and
ice trapped under the floor matting will not dry.
Relative humidity
Corrosion will be accelerated:
Iin areas of high relative humidity
Iespecially in areas where the temperatures
stay above freezing
Iwhere atmospheric pollution exists
Iwhere road salt is usedTemperature
A temperature increase will accelerate the rate
of corrosion to those parts which are not well
ventilated.
Air pollution
Industrial pollution, the presence of salt in the
air in coastal areas, or heavy road salt use will
accelerate the corrosion process. Road salt
will also accelerate the disintegration of paint
surfaces.To protect your vehicle from
corrosion:
IWash and wax your vehicle often to keep
the vehicle clean.
IAlways check for minor damage to the paint
and repair it as soon as possible.
IKeep drain holes at the bottom of the doors
and tailgate open to avoid water accumula-
tion.
ICheck the underbody. If any sand, dirt or
salt is accumulated, wash it off with water
as soon as possible.
INEVER remove dirt, sand or other
debris from the passenger compart-
ment by washing with a hose. Re-
move dirt with a vacuum cleaner or
broom.
INever allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle.
