​​How To Keep Your GMC Clean During The Winter​

February 10th, 2026 by

Even here in the Metroplex, your vehicle may not come home as clean as you would like during the wintertime. Road maintenance teams try to keep ice off our highways and streets as best they can. They can use salt or sand to de-ice roadways, depending on the location and the highway. However, if you ignore the grime that accumulates on your vehicle in winter, you may encounter long-term issues, such as rust and corrosion. How can you keep your GMC vehicle clean after one of our winter weather episodes?

It is always good practice to wash your vehicle regularly. Because salt and road grime can quickly build up, a good wash will loosen and remove them not just above the chassis, but also underneath it. You can run it through an automatic car wash. We suggest getting the package that includes an underbody wash.

Whenever you wash your vehicle, apply a protective wax coating. That way, you add a protective barrier between salt, dirt, and paint. It is suggested to apply the wax before any weather event to help it resist the elements. The result is a shiny and new vehicle every time.

You should also add a paint sealant, which will include either a film or a ceramic coating. This will last longer than traditional car wax and will resist dirt, salt, and grime more effectively. If you can invest in it, ceramic coating is more permanent than a film coating. It also needs annual maintenance to keep up the coating and finish. Regularly inspect your body panels. If needed, give it some touch-up paint. Our parts departments stock the ones that match your vehicle’s color.

For GMC owners, mud flaps and splash guards are best for protecting the sides of the vehicle from salt, grime, and dirt. They serve to protect the wheel wells from buildup. You can actually have these added to your GMC through our parts department. Another item you can get from our parts department is a cover for your GMC. They should be easy to put over your vehicle. It works both outside and in your garage.

Keeping your vehicle clean helps in many ways. Most importantly, it shows pride in ownership.
