The Surprising Reason Drivers Are Keeping Salt in a Glass Inside Their Cars
Have you ever opened your car door only to be greeted by a damp, musty smell? Or found yourself struggling to see through fogged-up windows every morning? These issues are more than just annoying—they’re signs of excess moisture trapped inside your vehicle.
The good news? You can tackle both problems with something you probably already have in your kitchen: table salt.
🧂 Not Just a Seasoning
Salt is hygroscopic, meaning it naturally pulls moisture from the air. By placing a small bowl or cup of salt inside your vehicle, you can significantly reduce humidity and condensation.
Here’s what salt does for your car:
🌫️ Prevents Foggy Windows: Less moisture means fewer misted-up glass surfaces.
🪑 Protects Upholstery: Low humidity helps keep fabric and cushions from absorbing moisture.
👃 Eliminates Odors at the Source: Unlike air fresheners that simply mask smells, salt tackles the cause—moisture—where mildew and bacteria thrive.
💰 Affordable & Effective: No gadgets or sprays required. Just salt, and maybe a container.
🧼 Extra Tips for a Drier Interior
Pair salt with these common items for extra moisture-fighting power:
Crumpled newspaper (great for short-term absorption)
Silica gel packets (often found in packaging)
Charcoal briquettes (they absorb odor too!)
📉 Why Act Fast?
Unchecked dampness can lead to long-term interior damage, mold growth, and bad smells that just won’t quit. But with a touch of salt, you’re protecting your ride—and your nose.
🚙 Final Thoughts
Maintaining a fresh, dry car interior doesn’t have to be expensive or complicated. Something as simple and affordable as salt can go a long way toward solving foggy windows and musty odors for good.
Whether you’re battling rainy weather, snow season, or simply park outdoors, using salt as a DIY dehumidifier is a smart, effective way to protect your ride—and your nose.
