At first glance, placing a glass of salt inside a car might seem unusual. But drivers are discovering that this simple trick can have a surprisingly practical benefit.
Salt naturally absorbs moisture. Excess humidity in a car can cause foggy windows, especially on cold or rainy mornings, which reduces visibility and creates a safety hazard.
By putting a small glass or container of salt—like sea salt or plain table salt—inside the car, drivers can use this natural property to pull moisture from the air. Over time, it helps keep the interior dry and windows clear.
How to Try It:
Fill a small glass or container with salt.
Place it in a cup holder or under a seat.
Replace the salt every couple of weeks or when it clumps.
This trick is cheap, chemical-free, and works silently in the background to keep your car fresh and safe—especially during colder months.
Next time your windows fog up, skip the sprays and give salt a try. You may be surprised at how effective this simple remedy can be.
