If you’ve been battling foggy windshields or that stubborn musty smell every time you get into your car, there’s a surprisingly simple fix—and it’s probably already in your pantry: salt.
More than just a common seasoning, salt works as a natural dehumidifier, pulling excess moisture from the air. Placing a small glass or container of salt inside your vehicle can help eliminate interior humidity, reduce condensation, and stop foggy windows before they start.
Thanks to its hygroscopic properties, salt literally attracts and absorbs moisture from the air. This makes it a smart, budget-friendly solution for keeping your car’s interior dry and comfortable.
Less moisture inside your vehicle means clearer visibility and fewer problems with mold, mildew, or upholstery damage—something every driver wants to avoid. And unlike synthetic air fresheners, which only mask odors, salt targets the source by preventing mold-friendly dampness.
The result? A fresher, cleaner-smelling car—naturally.
Excess humidity in cars isn’t just annoying—it can lead to long-term issues like window streaking, musty smells, and fabric deterioration. That’s why more drivers are turning to low-cost moisture control hacks like rock salt, crumpled newspaper, or even silica gel packs to keep their car interiors in top shape.
Don’t wait until mold sets in or your windows fog up on your morning commute. Drop a cup of salt into your vehicle today—this low-effort car hack could save you hundreds in cleaning and repairs, while keeping your daily drives more pleasant and healthier.
