Car doors are parts of cars that are prone to rust. It is because cars’ body, including car doors, is made from iron. When it makes contact with salt water and oxygen, rust can appear on it. Rust is not only found on old cars but also new vehicles.

Even when the vehicles are made from corrosion resistant materials, without proper protection and maintenance, they are still susceptible to rust. Rust should be treated as soon as possible otherwise; it will be getting more difficult to reverse. Here are 8 ways to prevent car doors from rusting.

8 ways to prevent car doors from rusting: keeping the cabin dry

Once rust starts on car doors, it will be very difficult to stop it from spreading to other parts of the vehicle. The first thing to keep a car free from rust is to keep the car interior dry. High moisture levels in the interior can spread to the exterior.

There are a number of reasons why car interior gets wet. Things like wet clothes, wet shoes, and wet pets can cause condensation inside the car, increasing the humidity level in the cabin. The water containing in wet clothes and other items evaporates in the cabin and can be heavily soaked, causing the carpet and seats wet. Other reasons for wet interior are a water leak and the absence of fresh air circulation.

Therefore, to keep car interior dry, make sure you don’t put any wet items into your car. If there are any spills, directly soak them up. It’s also important to check the windows and doors in case there are some leaks.

Park carefully

You might be questioning how and where a car is parked can cause rusting. The explanation is simple. Rust is more likely to form in a place that has high humidity level including in a damp, poorly ventilated garage. Therefore, you have to pay attention on where and how your park your car as it is one of the major determining factors that attract rust.

There are several ways to reduce condensation in a garage. Controlling garage’s temperature, applying floor coating, using a vapor barrier, and installing dehumidifier are things you can do to keep a garage dry. Parking your car outdoor on a surface covered by dirt, snow, and grass is also a bad idea. If you don’t want your vehicle to expose to unneeded moisture, try to park on a paved surface.

If you are interested in this device, it’s highly recommended to consult a technician because an electronic module is a bit pricey. Moreover, there are different electronic rustproofing methods available and each of them has its own strength and drawbacks.

Zink coated steel

Rusting happens when a chemical reaction between iron and oxygen is exposed to water. The oxygen takes electron from the iron, causing the iron to dissolve and slowly disappear, resulting in rust. This oxidation occurs with most metals and the process is gets more quickly when water combines with the chemicals contained in road salt and acid rain.

Cars are made of steel and iron is the main ingredient of steel. Coating the iron with zinc can be a way to prevent the car from rusting as the zinc dissolves first. It will protect the steel from corrosion until the zinc itself dissolves away.

Using rust prevention spray
