- How it works: Salt is hygroscopic—it pulls moisture from the air.
- What to do:
- Fill a sock or breathable pouch with coarse salt (like rock salt).
- Place it under your seat or in the footwell.
- It helps reduce interior humidity, which can lessen window fogging in damp weather.
- ✅ Bonus: Add a few drops of essential oil for a subtle fresh scent.
🚫 What Salt Won’t Do (Myth Busting)
- ❌ “Preserve your car’s interior” → False. Salt won’t protect upholstery.
- ❌ “Prevent flat tires” → No evidence.
- ❌ “Repel rodents” → Not reliable. Peppermint oil or sealed food storage works better.
⚠️ Important Safety Notes
- Never store salt in an open glass container in your car—it can spill, create mess, or damage surfaces.
- Use a sealed plastic jar or fabric sachet instead.
- Rinse off any salt residue from metal or paint promptly to avoid rust.
❤️ The Bottom Line
Keeping a small, sealed container of salt in your car isn’t magic—but it’s a low-cost, space-saving tool that can help in winter emergencies, reduce fog, or get you unstuck when you’re stranded.
“Smart drivers don’t rely on luck—they prepare with simple solutions.”
So go ahead—toss a jar of salt in your glove compartment or trunk this winter. Just keep it contained, and use it wisely. 🚗❄️✨
