The Surprising Reason Drivers Are Keeping Salt in a Glass Inside Their Cars

Tired of foggy windows and that lingering musty smell when you open your car door? The fix is surprisingly simple—and probably already in your kitchen: 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.
