Most common factors contributing to vehicle corrosion

- The accumulation of moisture-retaining dirt and debris in body panel sections, cavities, and other areas.

- Damage to paint and other protective coatings caused by gravel and stone chips or minor traffic accidents.

Environmental factors influence the rate of corrosion

Moisture

Accumulation of sand, dirt and water on the vehicle body underside can accelerate corrosion.

Wet floor coverings will not dry completely inside the vehicle, and should be removed for drying to avoid floor panel corrosion.

Relative humidity

Corrosion will be accelerated in areas of high relative humidity, especially those areas where the temperatures stay above freezing where atmospheric pollution exists, or where road salt is used.

Temperature

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

- Wash and wax your vehicle often to keep the vehicle clean.

- Always check for minor damage to the paint and repair it as soon as possible.

- Keep drain holes at the bottom of the doors open to avoid water accumulation.

- Check the underbody for accumulation of sand, dirt or salt. If present, wash with water as soon as possible.

- NEVER remove dirt, sand or other debris from the passenger compartment by washing it out with a hose.

Remove dirt with a vacuum cleaner.

- Never allow water or other liquids to come in contact with electronic components inside the vehicle as this may damage them.

Chemicals used for road surface deicing are extremely corrosive. They accelerate corrosion and deterioration of underbody components such as the exhaust system, fuel and brake lines, brake cables, floor pan and fenders.

In winter, the underbody must be cleaned periodically.

For additional protection against rust and corrosion, which may be required in some areas, consult a NISSAN dealer.
