Sometimes the easiest solutions come from everyday household items. One surprising example is keeping a small glass of salt in your car. Many drivers have found this to be a simple way to reduce moisture inside their vehicles, especially during colder or rainy months. Salt naturally absorbs humidity from the air, making it a practical option for keeping the interior environment more comfortable.
Excess moisture in a car can often lead to foggy windows, which can be both inconvenient and distracting while driving. By placing a container of salt in the cabin, drivers may notice that the windows stay clearer for longer periods of time. While it won’t completely replace regular ventilation or professional cleaning, this trick can provide an extra layer of prevention against fog build-up.
Another benefit of using salt is its affordability and availability. Unlike specialized car products, salt is inexpensive and easy to find. If used correctly—kept in a secure, open container where it can absorb air moisture—it can last for several weeks before needing replacement. For those who drive daily or park outdoors, this method is a quick and low-cost option to try.
Of course, this tip is not a miracle fix, but rather a simple aid that works best when combined with proper car care. Ensuring your vehicle is well-ventilated, regularly drying damp carpets, and checking for leaks are still the most reliable ways to keep your car fresh and clear of excess humidity. Still, adding a small glass of salt is an easy step that may help improve comfort and visibility during your drives.
