🚗🧂 Put 1 Glass of Salt in Your Car? Here’s the Truth Behind This “Hack”
Introduction
You might have seen claims that placing a glass of salt inside your car can solve common problems like foggy windows or moisture buildup. It sounds unusual-but there’s actually some science behind it. Still, it’s not quite the miracle fix some posts suggest.
What the Salt Trick Is Supposed to Do
Salt is a hygroscopic substance, meaning it can absorb moisture from the air. The idea is that placing a container of salt in your car helps:
Reduce humidity inside the cabin
Prevent window fogging
Limit musty odors caused by dampness
• Does It Actually Work?
Partially-yes, but with limits.
Salt can absorb small amounts of moisture, especially in a closed environment like a parked car. However:
It works slowly
It can’t handle large amounts of moisture
