Whoa 😲 — putting a whole glass of salt in your car is not a miracle trick and could actually cause serious damage if taken literally. Headlines like that are usually clickbait.
But let’s decode what this type of “tip” usually refers to:
🧂 Common “Salt in Car” Tips and Their Real Purposes
1️⃣ Absorb Moisture
-
Salt is hygroscopic (absorbs water).
-
Some people put a small container of salt in cars to reduce humidity and prevent window fogging or musty smells.
-
✅ Works in small amounts
-
❌ A whole glass could spill, damage surfaces, or corrode metal
2️⃣ Remove Odors
-
Salt can neutralize certain odors, especially in carpet or upholstery.
-
Usually combined with baking soda, not plain salt poured into the car.
3️⃣ Ice & Traction (Winter)
-
Salt is sometimes put in cars outside, not inside, to melt ice on windshields or prevent tires from slipping.
⚠️ Why a Full Glass Inside the Car Is a Bad Idea
-
Can scratch surfaces if spilled
-
Can corrode metal parts
-
Creates a mess that’s hard to clean
✅ Safe Alternative
-
Use a small open container or sock with salt, place under the seat for moisture control
-
Or use baking soda or silica gel packets to absorb humidity and odors safely
💡 Bottom line: There’s no magic “salt glass” that fixes your car overnight. Small amounts can help with moisture/odor, but anything bigger is dangerous.
If you want, I can share a safe, practical method to keep your car dry, smell-free, and prevent fogging that actually works.
