The most common causes of corrosion
The most common causes of corrosion are:
- Road salt, dirt and moisture on the underside of the car body.
- Damage to paintwork or protective coatings from rock, gravel, abrasion, or minor scratches or dents that corrode bare metal.
Zones of high corrosion hazard
Corrosion protection is especially important if you live in an area where your vehicle is constantly exposed to corrosive substances. Common causes of accelerated corrosion include salt exposure, dust suppression chemicals, sea air, and industrial pollution.
Moisture causes corrosion
Humidity is one of the conditions in which corrosion is most likely. For example, corrosion is accelerated by high humidity, especially at temperatures slightly above the freezing point of water. Under these conditions, aggressive substances are kept in contact with the surfaces of the vehicle by moisture for a long time. at this temperature, it evaporates slowly.
Adhering dirt has a strong corrosive effect, which dries poorly, retaining moisture. The dirt may appear dry, but it still contains moisture that can corrode. High temperatures also accelerate corrosion in poorly ventilated areas where moisture can settle. For all these reasons, it is especially important to keep the vehicle clean and to remove dirt and buildup of other foreign materials. This applies not only to visible areas of the body, but above all to the bottom of the car.
