🌬️ 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.
