Put 1 Glass of Salt in Your Car
Every day starts the same way for millions of drivers: you step outside, still half-asleep, coffee in hand, ready to face the morning… only to be greeted by a car that feels like it spent the night inside a rainforest. Fogged-up windows. Damp seats. That strange musty smell that definitely wasn’t there yesterday.
1.
You wake up.
It’s cold.
Damp.
You rush to the car—late again—and throw open the door.
And there it is:
Fogged-up windows
A musty smell that wasn’t there yesterday
That weird dampness on the seats… even though it didn’t rain
Sound familiar?
We’ve
all battled car humidity—that invisible enemy that turns your morning commute into a steam room session with poor visibility and questionable air quality.
But what if the fix wasn’t a $30 dehumidifier or an overpriced spray?
What if it was already in your kitchen?
Meet the salt hack—a simple, cheap, science-backed trick that mechanics, RV owners, and boaters have sworn by for years.
How It Works: Salt Is a Natural Dehumidifier (Seriously):
How It Works: Salt Is a Natural Dehumidifier (Seriously)
Salt isn’t just for fries.
It’s hygroscopic—meaning it naturally pulls moisture out of the air.
Leave a bowl of salt in a humid space?
It will slowly clump, harden, or even dissolve as it absorbs water vapor.
In your car, this means:
Less fog on your windows
Drier upholstery and floor mats
No more musty “wet dog” smell (even if you don’t own one)
Reduced risk of mold and mildew buildup
It’s like having a silent guardian working 24/7—no batteries, no noise, no cost.
How to Do It (3 Easy Steps)
Step 1: Grab a Container
Use a small glass, mason jar, or plastic container
Wide opening = more surface area = better absorption
Avoid metal containers—they can rust from moisture
Step 2: Fill It With Salt
Pour in ½ to 1 cup of plain table salt or rock salt
No iodine needed—just basic salt works fine
Optional: Add a few drops of essential oil (e.g., tea tree or lavender) for a fresh scent
Step 3: Place It in Your Car
Put it on the floor near your feet (front or back seat)
Or place it on the center console—out of the way but effective
Replace or refresh every 2–4 weeks (when salt clumps or dissolves)
Pro tip: Cover the top with a coffee filter or paper towel secured with a rubber band—lets air in, keeps dust out.
