Nissan Maxima: 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.
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.
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.
