Does road salt damage my car’s paint?

Road salt is less likely to damage intact paint than most people think. Factory clear coat protects painted surfaces from most corrosion. The bigger risk is the unpainted or lightly protected areas, such as the undercarriage, wheel wells, and the back sides of body panels, where salt collects and stays.

How often should I wash my car in the winter to remove salt?

Plan on an undercarriage rinse about every couple of weeks when roads are salted, and after any major storm. If you drive on heavily treated roads frequently, wash more often. Focus on the underside, wheel wells, and lower panels, since that’s where salt builds up and causes rust.

Is an undercarriage wash worth it?

Yes, an undercarriage wash is one of the most useful things you can do for your car in winter. It reaches the areas where salt is most harmful and hardest to see. A regular exterior wash alone may leave salt packed into the frame, suspension areas, and inner panels.

Why does rust show up under the paint?

Rust under the paint usually starts from the back side of the panel, where protection is thinner. Moisture and salt work through the metal from the inside until the paint begins to bubble. By then, the corrosion underneath may be larger than it looks, so an inspection is a good idea.

Does a scratch or chip make salt damage worse?

Yes. Once a chip or scratch breaks through the clear coat and paint, the metal underneath is exposed to salt and moisture. Repairing chips and scratches before winter helps keep corrosion from starting.
