Most drivers rely on expensive sprays, gadgets, or constant wiping to fight foggy car windows and damp interiors. But what if the solution was already sitting in your kitchen? Believe it or not, something as ordinary as table salt can make a big difference. For generations, people have used salt to keep moisture at bay in their homes, and now more and more drivers are discovering that the same trick works wonders in their cars. Just a small glass or container of salt placed inside the vehicle can quietly work to absorb excess humidity, making your daily drive clearer and more comfortable.
Excess moisture inside a car isn’t just an inconvenience — it can create foggy windows that block visibility and make driving stressful, especially during rainy days or frosty mornings. By placing salt in a secure, open container inside your car, you’re essentially giving yourself a natural, low-cost dehumidifier. Many drivers report that their windows stay clearer for longer, reducing the need for constant wiping or waiting for the defroster to catch up. It’s not a perfect fix, but it can provide noticeable relief.
Another reason this method is catching attention is its simplicity. Unlike specialized car-care products that can cost quite a bit, salt is affordable, widely available, and requires no special setup. A small glass or even a cloth pouch filled with salt can last for weeks before needing to be replaced. It’s an easy step for people who drive daily, park outside, or struggle with damp interiors during the colder months.
Of course, salt alone isn’t a complete solution. Regular car care still matters — keeping the vehicle well-ventilated, drying damp carpets, and checking for leaks remain essential steps. But as an extra layer of defense, this little kitchen trick can be surprisingly effective. Sometimes, it’s the smallest changes that make driving easier, safer, and more comfortable. So the next time you notice fog creeping up on your windshield, remember: a simple glass of salt might just do the trick.
