Put a Glass of Salt in Your Car …Simple Humidity Hack
Dealing with excess humidity in your car? You’re not alone. High moisture levels inside your vehicle can lead to foggy windows, musty odors, and even mold growth—all of which can make your drive uncomfortable and potentially harmful to your car’s interior. Luckily, there’s an easy, affordable solution you can try today: a glass of salt.
Why It Works: The Science Behind the Salt Hack
Salt is a natural desiccant, meaning it has hygroscopic properties—it attracts and absorbs moisture from the surrounding air. By simply placing salt in your car, you can lower the humidity levels without relying on chemical dehumidifiers or costly gadgets. It’s a safe, non-toxic way to create a drier environment inside your vehicle.
How to Use Salt to Reduce Car Humidity
1. Choose the Right Salt
Use coarse salt, rock salt, or even Epsom salt for best results. These types of salt have larger crystals, which provide more surface area to absorb moisture.
2. Prepare Your Container
Fill a dry glass, bowl, or small breathable container with your chosen salt. Avoid sealed containers—they won’t allow air circulation.
3. Place It Strategically
Set the container in a stable, out-of-the-way spot like the cup holder, under the seat, or in a door pocket. Be sure it won’t tip over during driving.
4. Monitor and Replace
Check the salt every 2–3 weeks. When it becomes clumpy or wet, it’s time to replace it with fresh salt.
