Keep your car clean
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 vehicle 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 end of the winter period.
When washing the underbody of your vehicle, pay special attention to the parts under the fenders and other hidden parts. 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 door bottom panels, reinforcements and frame parts, make sure that the drain holes are open 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 when 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 repaired 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 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.
