Salt isn’t just for seasoning or melting driveway ice. Mechanics recommend it for reducing car moisture. Just place a glass of salt inside your vehicle, and it goes to work immediately.
Thanks to its hygroscopic properties, salt draws moisture from the air. This helps lower humidity levels and prevents annoying condensation from forming on windows and seats.
Why Salt Works So Well
Salt naturally attracts and holds moisture. That makes it a perfect choice for small, enclosed areas like your car’s interior. It’s also cheap, easy to find, and totally safe.
Even better? It doesn’t just dry out the air—it helps fight odors too. Unlike air fresheners that cover up smells, salt neutralizes them by removing the damp conditions that bacteria and mold love.
