Dealing with foggy windows or that musty smell in your car? There’s a surprisingly simple fix: a glass of salt. Found in every kitchen, salt doesn’t just season food—it also absorbs moisture from the air, helping to reduce humidity inside your vehicle.
Salt is naturally hygroscopic, meaning it pulls moisture from its surroundings. By placing a small glass filled with salt in your car, you can reduce condensation on windows and prevent damp seats, especially during colder or rainy months.
What makes salt so effective is its ability to get to the root of the problem. Unlike air fresheners that only cover up odors, salt absorbs the moisture where bacteria and mold grow—helping to eliminate unpleasant smells at the source.
If ignored, humidity can lead to lasting damage inside your car. Thankfully, simple items like salt, crumpled newspaper, or silica gel offer a cheap and effective way to keep your interior fresh and dry. Give it a try—it’s easy, affordable, and it works.
