The Bottom Line
Putting a glass of salt in your car isn’t a complete myth—but it’s far from a miracle solution.
Yes, salt can absorb some moisture. But in most real-world situations, it’s not powerful enough to make a meaningful difference.
If you’re serious about keeping your car dry, fresh, and comfortable, it’s better to focus on proven methods like proper ventilation, moisture control products, and fixing any underlying issues.
Final Thought
Sometimes the simplest ideas are worth trying—but they’re not always the most effective.

And if you’ve already tried it… you might have noticed the truth firsthand.
