Put a Glass of Salt in Your Car—Here’s Why Every Driver Should Try It

Tired of foggy windows, damp seats, or that lingering musty smell in your car? There’s a surprisingly simple fix—and it’s sitting in your kitchen: salt.

This Unexpected Hack Fig.hts Car Humidity

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.

No Ocean Smell—Just Fresh Air

Worried your car might start smelling like a salty beach? Don’t be. Salt actually improves air quality. It keeps things fresh by drying out the environment where foul odors usually form.

Other Budget-Friendly Alternatives

Not convinced about using salt? Try these other moisture-fighting tricks:

• Newspaper: Crumple sheets and tuck them around your car. They soak up moisture surprisingly well.

• Silica Gel: Those tiny packets in shoeboxes? They work like mini dehumidifiers. Toss a few in your glove box or under the seats.

Take Action Before Moisture Damages Your Car

Letting humidity build up can lead to more than just discomfort—it can damage your car’s interior over time. Don’t wait until you’re stuck with foggy windows or a funky smell.

Instead, use salt (or one of the alternatives) to keep your ride dry, clean, and fresh. It’s simple, affordable, and effective.
