Vehicle Corrosion Prevention
Anti-Corrosion Measures
Environmental Factors Affecting the Rate of Corrosion
● Regularly wash and wax the vehicle to keep it
clean.
● Frequently inspect for minor paint damage
and repair it promptly.
● Check the underside of the car for
accumulations of sand, dirt, or salt, and wash
them off with water as soon as possible.
Ensuring the Vehicle is Corrosion-Free
● Accumulation of damp dirt or debris in the
body panel cavities or other areas.
● Damage to paint or other protective coatings
caused by sand and pebbles or minor trafc
accidents.
Most Common Factors of Vehicle Corrosion
Accumulations of grit, dirt, and moisture
under the body can accelerate body corrosion.
Damp carpets inside the vehicle can take a
long time to dry completely, and to prevent oor
corrosion, they should be removed and dried.
Moisture
Higher temperatures can accelerate the
corrosion of parts in poorly ventilated conditions,
especially in areas where the temperature
remains above freezing.
Temperature
Industrial pollution, the presence of salt in
the air in coastal areas, or the extensive use of
salt on roads can accelerate corrosion. Salt on
roads can also speed up the aking of paint.
Air Pollution
In areas with high relative humidity,
corrosion can accelerate.
Relative Humidity
CAUTION
● Do not use water to directly wash the
passenger compartment to remove dirt,
sand, or other debris.Instead, use a
vacuum cleaner or broom to remove the
dirt.
● Avoid water or other liquids coming
into contact with the interior electrical
components, as this can damage them.
De-icing agents and snow-melting
chemicals used on roads are corrosive and can
accelerate the aging and corrosion of underbody
components such as exhaust systems, parking
brake control cables, brake lines, floor panels,
and fenders. Therefore, after driving on such
roads, the underside of the vehicle should be
cleaned promptly.
Other rust and corrosion prevention
measures may have specific requirements in
some regions.Consult an authorized dealership
for more information.
