You can plan to go through the car wash every few weeks. Then you can take it a step further with a once-a-month more detailed clean by hand. This will allow you to rub down any areas that are more susceptible to water or salt buildup.

Try An Undercoating

Because many rust protection products are expensive, drivers tend to opt for an undercoating instead because it can be a cheaper alternative. It can be done with oil and applied to the car to absorb salt to prevent rust.

What Causes Cars To Rust In Winter?

Winter is the season when cars are exposed to more moisture and difficult elements. This is the time when rust is most likely to appear on cars.

The most common cause of rusting is oxidation. Rusting happens when iron atoms break down and give up electrons. This is an electrochemical reaction known as corrosion.

The iron ions then combine with oxygen molecules and form iron oxides, which are a kind of brownish-black pigment that gives the surface of metal items a dull or dark color.

The following are some of the most common causes of cars rusting in winter.

Road Salt Residue

Rusting can occur when you have salt residue on your car from the road. This can happen if you are not careful and don't clean your car regularly to remove the salt residue during the winter season.

When it rains or snow outside, excess water will find its way into the cracks of your car and then freeze causing ice and snow build-up. This causes a buildup of water that can cause corrosion over time.

To prevent rust from forming, you should take some preventative measures. The best way to avoid rust is to keep your car clean and dry.
