Winter roads are often treated with salt to prevent ice buildup, but while this keeps roads safer, it can also lead to corrosion and vehicle damage. Here’s what you need to know about salt damage and how to protect your car this winter.
How does road salt work?
Road salt works by lowering water's freezing point, making it harder for ice to form on the road. This keeps roads safer and helps prevent accidents.
On the other hand, when salt sticks to your car, it creates the ideal environment for rust and corrosion, especially in areas with frequent snow and icy conditions.
What is the extent of road salt damage on your car?
Salt is corrosive, and when mixed with water and oxygen, it accelerates rusting on metal surfaces. This corrosion often starts on the car’s undercarriage, where salt and moisture can collect in hard-to-reach places.
Over time, rust can spread to crucial parts like the brakes, exhaust system, and even the car’s structural frame, leading to costly repairs and safety issues.
What parts of your vehicle are most at risk?
The undercarriage, including the brake and fuel lines, is particularly prone to salt damage because it’s closest to the road and exposed to salt spray.
Wheel wells, where salt can accumulate, and the lower sections of car doors are also vulnerable areas. Additionally, paintwork can be affected if salt isn’t removed regularly, leading to chipping and peeling.
How to know if your car has suffered road salt damage
Rust spots on the paint, discoloration, and a dull finish are clear indicators of salt damage. A more thorough inspection may reveal rust or corrosion on metal parts underneath the vehicle.
Also, if you hear any unusual noises or changes in the handling of your car, these can also be signs of rust affecting important components.
How to protect your car from road salt damage
Protecting your car from salt damage requires some regular maintenance and preventive care:
Wash your car frequently
During winter, wash your car every two weeks with a pressure washer to reach difficult spots, focusing on the undercarriage and wheel wells.
Wax your car
Applying a coat of wax before winter provides an extra layer of protection for your paint, making it harder for salt to stick. This can reduce the likelihood of rust forming.
Consider undercoating
Applying an undercarriage sealant or undercoating product before winter can add a protective layer that guards metal parts from moisture and salt, reducing rust formation.
Park in a garage
When possible, parking in a garage can help keep your car dry and prevent salt buildup, especially during snowy or wet conditions.
How often should you inspect your car for road salt damage?
With winter nearly here, it’s wise to inspect your car for salt damage regularly and check for signs of rust on the undercarriage and wheel wells.
If you're unsure, consider having a professional mechanic inspect it. Early detection can help you address small rust spots before they become bigger problems.
