Put 1 Glass of Salt in Your Car: The Surprising Hack Every Driver Needs to Know

🌫️ Why Your Car Gets Foggy & Musty

🌫️ Why Your Car Gets Foggy & Musty

Moisture builds up in your car from:

Wet shoes, jackets, or umbrellas

Spills (coffee, water, pet accidents)

Humidity from your breath while driving

Poor ventilation

That trapped moisture leads to:

Foggy windows (annoying and dangerous)

Musty odors (hello, mildew!)

Mold growth (on seats, carpets, AC vents)

Most people reach for air fresheners or dehumidifier bags — but here’s a cheaper, natural alternative…

🧂 How Salt Fights Car Humidity (The Science)

Salt is hygroscopic — meaning it naturally absorbs moisture from the air.

When you leave an open container of salt in your car:

It pulls water vapor out of the air

Reduces overall humidity

Prevents condensation on cold surfaces (like glass)

Helps stop musty smells before they start

Think of it as a passive dehumidifier — no batteries, no noise, no cost.

🔬 Bonus: Unlike silica gel or commercial packs, salt doesn’t saturate quickly — it keeps working until it clumps or dissolves.
