How Often to Wash Your Car in Winter Salt

Winter salt is a common sight on roads during the colder months. While this helps to melt away snow and ice, it can be detrimental to your car’s exterior. The salt can cause rust and other damage if left untreated. So, how often should you wash your car during the winter months to prevent salt damage? Let’s explore this question in more detail.

What is Winter Salt?

Winter salt, also known as road salt or rock salt, is a mixture of sodium chloride and other chemicals that are used to melt ice and snow on roads. It’s often spread by snowplows and other vehicles, as well as by hand. While it helps to make driving safer during the winter, it can be harmful to your car’s exterior.

Why is Winter Salt Harmful to Your Car?

Winter salt is harmful to your car because it can cause rust and other damage to the exterior. When salt comes into contact with your car’s metal surfaces, it can corrode and weaken them over time. This can lead to rust and other types of damage that can be expensive to repair.

How Often Should You Wash Your Car in Winter Salt?

The frequency with which you should wash your car in winter salt depends on a number of factors, including how often you drive, how much salt is on the roads, and the severity of the weather. As a general rule, you should aim to wash your car at least once a week during the winter months.

What Type of Car Wash Should You Use?

When washing your car in winter salt, it’s important to use a car wash that is designed to remove salt and other winter grime. Look for a car wash that uses a high-pressure water system and a specialized soap that is designed to break down and remove salt from your car’s exterior.

Should You Wash Your Car Immediately After Driving in Winter Salt?

It’s a good idea to wash your car as soon as possible after driving in winter salt. This will help to minimize the amount of time that the salt has to corrode and damage your car’s exterior. If you can’t wash your car right away, try to at least rinse off the salt with a hose or other water source.

What Should You Pay Attention to When Washing Your Car in Winter Salt?

When washing your car in winter salt, pay attention to the undercarriage and other areas that are most susceptible to salt damage. Make sure to use a high-pressure washer to remove salt from these areas, and consider applying a rust inhibitor to help protect your car from future damage.

What Other Steps Can You Take to Protect Your Car from Winter Salt?

In addition to washing your car regularly, there are other steps you can take to protect your car from winter salt. Some of these include:

  • Applying a rust inhibitor to your car’s exterior
  • Waxing your car to create a protective barrier
  • Covering your car with a tarp or other protective covering
  • Parking your car in a garage or other covered area whenever possible


Winter salt can be harmful to your car’s exterior, but with proper care and maintenance, you can help to minimize the damage. By washing your car regularly and taking other protective measures, you can keep your car looking great and running smoothly all winter long.
