🚗 Put a Glass of Salt in Your Car — This Vital Hack Could Save You a Headache (A Cop Told Me About It!)

When it comes to driving, we all know the basics: check your oil, rotate your tires, don’t text and drive. But every once in a while, you stumble across a simple car hack that feels like insider info — and this one came straight from a police officer.

Here’s the trick:
👉 Put a small open glass of salt in your car.
Sounds odd, right? But it turns out, this humble kitchen staple can do more for your vehicle than you’d think.

Let’s break down why this works, and why every driver should try it.


🧂 Why Salt in the Car?

Salt — especially table salt or rock salt — is highly absorbent. It naturally pulls moisture out of the air, which can solve a bunch of common car problems, especially in humid or colder climates.


🌀 The Main Benefits of the Salt-in-a-Glass Hack

1. Prevents Foggy Windows

Ever get in your car on a chilly morning and find the windshield fogged up from the inside? That happens because of moisture trapped in your car. Salt absorbs that extra humidity, reducing interior fog, which means:

  • Better visibility
  • Safer driving
  • Less time waiting for the defroster to kick in

🚓 A traffic officer once told me they recommend this trick during winter months to reduce fog buildup that could impair visibility.


2. Reduces Moisture and Damp Smells

Cars—especially older ones—can develop musty, damp odors, especially if you’ve had spills, leaks, or wet shoes on the floor mats. Salt can help dry out the air and prevent mold or mildew from forming in hidden spots like:

  • Carpeting
  • Under seats
  • Trunk area

3. Prevents Frost on the Inside of Windows

In cold climates, that morning layer of ice on the inside of your windshield is not just annoying — it can be dangerous. Salt in the car helps reduce the interior moisture that leads to frost buildup.


4. Natural and Chemical-Free

Unlike commercial moisture absorbers or car fresheners, salt is non-toxic, scent-free, and chemical-free. You don’t have to worry about synthetic fragrances or unnecessary ingredients—just simple science doing its thing.

  • A small glass or plastic container (avoid metal)
