As winter descends, the picturesque landscapes filled with snow and ice bring along a less welcome companion – road salt. While road salt, a mixture of sodium chloride, calcium chloride, and sand, is essential for maintaining safe driving conditions, it poses a significant threat to your vehicle, particularly the car paint.
This article delves into the damaging effects of road salt on automobile paint and how you can protect your vehicle during the harsh winter months. Before starting the article, watch the video below:
What is Road Salt?
Road salt is primarily used to lower the freezing point on road surfaces, reducing ice formation and providing safer driving conditions. The most common types of road salt are sodium chloride and calcium chloride, often mixed with sand to improve traction and keep the salt in place. These salts may do serious damage to your car’s paint and substructure even if they are good for enhancing road safety.

What Does Road Salt Do?
Road salt sticks to the surface of your car and, when exposed to moisture, creates a salt brine. The tiniest scratches and fissures in the paint of your automobile might allow this brine to leak in. When the temperature drops, the brine can freeze and expand, exacerbating the damage to the paint. Over time, this cycle of damage can lead to extensive rusting and corrosion.

How to Tell if a Car Has Salt Damage

How to Clean Road Salt Off Your Car
Regular car washes are crucial in the winter months. They help remove the salt from your automobile’s surface, preventing it from forming a corrosive brine. Pay close attention to the undercarriage, brake lines and fuel lines which are especially vulnerable to salt exposure. Additionally, a solution of baking soda and water can help neutralize the salt and prevent further corrosion.
How to Protect Your Car Paint During the Winter
The easiest approach to avoid salt damage to your vehicle’s paint is to protect it before winter. Here are some techniques to protect the paint on your vehicle:
Wax Your Car Before Winter Comes
Waxing on car paint
Before winter sets in, you should polish your vehicle. You’ll have more time to get to a vehicle wash and an additional layer of protection thanks to the wax.
Wash Your Vehicle Regularly
To stop rust on your mechanical components, be sure to obtain a wash that additionally cleans the undercarriage. To give the water an opportunity to dry before the temperature lowers, we strongly advise getting this wash while the temperature outside is at least 40 degrees throughout the day.

Protect Your Paint
Rust gets into exposed metal surfaces, so make sure the paint covers everything it should. Use touch-up paint to keep salt from wearing away into dings and scratches.
Replace Rusted Parts
Once rust forms, it’s difficult to remove and can spread to other parts. You can try to remove it from the surface, but in some cases, it’s easier to replace painted parts entirely.

Using Products to Help Protect Your Car
Products like Ceramic Pro, paint protection film and automotive coating systems offer additional protection. Regular applications of products like Underbody Rinse, Salt Shield, and Ultimate Ceramic Finish can also help protect your car from the corrosive effects of road salt.
Conclusion
While road salt is a necessary evil in winter driving, it doesn’t mean your car’s paint has to suffer. With regular care, timely washes, and the right protective measures, you can keep your vehicle looking its best, no matter what the season throws at it.
