This simple property makes it an excellent solution for managing excess dampness inside your car.
With lower humidity levels, you’ll experience fewer fogged-up windows and prevent moisture from soaking into your upholstery—an easy, low-cost fix for a widespread issue.
What makes salt especially effective is that it tackles the root of the problem.

The result? A naturally fresher, drier interior—without relying on artificial scents.
