At first glance, placing a glass of salt inside a car might seem strange—but this simple trick is gaining attention among drivers for a surprisingly practical reason.
Salt is well known for its ability to absorb moisture, and that’s exactly why it’s being used inside vehicles. If you’ve ever stepped into your car and noticed foggy windows, especially on cold or rainy mornings, the culprit is excess humidity in the air. This moisture can make your windshield and windows fog up, reducing visibility and creating a potential driving hazard.
By placing a small glass or container of salt—such as sea salt or even plain table salt—inside the car, drivers are using salt’s natural dehumidifying properties to pull moisture out of the air. Over time, this helps keep the car’s interior dry and reduces the chances of fogged-up windows.
How to Try It:
- Fill a small glass or open container with salt.
- Place it in your car’s cup holder or under a seat.
- Replace the salt every couple of weeks or when it starts to clump.
Not only is this trick affordable and chemical-free, but it also works silently in the background, helping your car stay clear, fresh, and safe—especially during colder months.
So the next time you’re dealing with foggy windows, skip the sprays and give salt a try. You might be surprised by how effective this old-school remedy really is.
