If you’ve ever stepped into your car and been met with foggy windows and a lingering musty odor, you know how uncomfortable it can feel. These issues are especially common in older vehicles, where moisture can easily build up over time. Fortunately, there’s a simple and affordable solution that doesn’t require expensive equipment or chemical sprays—it may already be in your home.
Salt, a common household ingredient, has powerful moisture-absorbing properties. It is hygroscopic, which means it naturally draws water from the surrounding air. When placed inside your car, salt helps reduce humidity levels, limiting condensation on the windows and creating a drier interior. This can make a noticeable difference in both comfort and visibility during your daily drive.
