Moisture
Wet deposits of sand and dirt that accumulate on the underbody and in body cavities accelerate corrosion. Floor mats that gradually accumulate moisture cannot dry completely inside the vehicle and must be removed periodically to dry.
High air humidity
Body corrosion accelerates at high air humidity, especially if the humidity is combined with a constant positive air temperature, significant atmospheric pollution and regular use of salt compositions for road treatment.
Air temperature
With an increase in air temperature, the rate of corrosion development increases, especially in poorly ventilated areas of the body. Corrosion processes are accelerated in regions where the air temperature remains constantly above zero.
Air pollution
Industrial air pollution and high salt content (on sea coasts or with intensive use of salt compositions to combat ice) accelerate the corrosion process. Road salt also accelerates the destruction of the paintwork.
