You can prevent corrosion. The best way to prevent corrosion is to keep your vehicle clean. It is very important to pay special attention to the bottom of the car.
If you live in the region (country), where your car is regularly exposed to corrosive factors - where roads are salted, near the sea, in regions with heavy industrial pollution, acid rain, etc. – You must take special measures to prevent corrosion. In winter, spray the underside of your vehicle with water at least once a month and rinse it thoroughly after the winter period is over.
When washing the bottom of the car, pay special attention to the parts under the fenders and other parts hidden from view. Do your work carefully. Simply washing rather than thoroughly cleaning accumulated dirt can accelerate corrosion rather than prevent it. Pressurized water and steam are quite effective in removing accumulated dirt and corrosive materials.
When cleaning the bottom panels of doors, reinforcements and frame parts, make sure that the drainage holes are free so that moisture can evaporate and not accumulate inside, accelerating the appearance of corrosion.
Keep your garage dry. Do not leave your vehicle in a damp, poorly ventilated garage. This creates excellent conditions for corrosion. This also applies if you wash your car inside the garage or drive into the garage with a wet, snowy or muddy car. Even a heated garage can contribute to corrosion if it is poorly ventilated and moisture does not evaporate.
Keep paint and trim in good condition. Scratched or chipped paintwork should be covered with repair paint as soon as possible to reduce the risk of possible corrosion. If bare metal is found, it is recommended to contact a paint shop.
Don't forget about the interior. Moisture can collect under floor mats and carpeting and cause corrosion. Periodically check that there is no moisture under floor mats and carpeting. Be especially careful if you are transporting fertilizers, cleaning materials or chemicals in a vehicle. Such materials must be transported in special containers and any drops or stains must be washed off with clean water and dried thoroughly.
