🚗 Put a Glass of Salt in Your Car: The Vital Hack Every Driver Should Know (A Cop Told Me About This!)

Sometimes, the most surprising tips come from those who see it all — and in this case, it was a friendly police officer who shared a simple car hack that’s been a total game changer:
Put a glass of salt in your car.

Sounds odd? Maybe.
But it turns out this old-school trick has been quietly used for years by seasoned drivers, mechanics, and yes — even law enforcement. And it could save you money, prevent discomfort, and even help you drive more safely in different seasons.

Here’s why you’ll want to keep a glass of salt in your vehicle — especially if you live in areas with humidity, cold winters, or foggy windows.

🧂 What Happens When You Put Salt in Your Car?

Salt is a natural dehumidifier. It attracts and absorbs moisture from the air — which makes it incredibly useful inside a vehicle. When placed in a container or cloth bag, it can:

✅ Prevent Foggy Windows

Tired of your windshield and windows fogging up in the morning or during damp weather?
That’s caused by excess moisture in the air inside your car. A glass of salt helps reduce that moisture, keeping your windows clear and safe.

✅ Reduce Musty Odors

If your car smells stale, musty, or just… off, it might be due to hidden humidity under the seats or in the vents. Salt absorbs that moisture — and along with it, the bad smells.

✅ Prevent Mold and Mildew

Excess dampness can lead to mold growing in hard-to-reach places like carpets or air vents. Salt can help prevent mold buildup, especially during rainy seasons or winter.

✅ Help in Cold Climates

Ever dealt with frozen locks or icy windshields? Salt reduces moisture inside the car that can condense and freeze on the glass. It's not a miracle cure, but it can help reduce the chances.

🧼 Bonus Tip: Use a Sock!

Some people fill a clean sock with salt, tie it off, and place it under the seat. It works just as well and is less likely to tip over.
