Fogged windows and musty smells on damp mornings are usually caused by excess humidity inside your car. Over time, that moisture can make driving uncomfortable and even damage upholstery, electronics, and interior surfaces.
A simple and inexpensive solution is plain table salt. Salt is hygroscopic, meaning it naturally absorbs moisture from the air. Placing a small bowl of salt in your car allows it to steadily reduce humidity, helping clear fogged windows and dry out seats.
Lower moisture levels also help prevent musty odors by limiting the growth of mold and bacteria. If salt isn’t available, crumpled newspapers or silica gel packets can work as effective alternatives, absorbing excess moisture in the same way.
Managing car humidity improves comfort and protects your vehicle’s interior. A small bowl of salt is cheap, easy, and surprisingly effective—no sprays or gadgets required. With this simple pantry hack, you get clearer windows, drier seats, and fresher air.
