Nissan Altima Owners Manual: Environmental factors influence the rate of corrosion


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 and where atmospheric pollution exists and road salt is used.


High temperatures 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 accelerates the corrosion process. Road salt also accelerates the disintegration of paint surfaces.

    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 c ...

    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 t ...
