Putting a glass of salt in your car is actually a clever hack that many drivers use, and it’s backed by simple science. Here’s what it does and why it works:
1. Absorbs Moisture
- Salt is a natural desiccant, meaning it draws water out of the air.
- Keeping a glass of salt in your car can reduce interior humidity, especially in humid or rainy climates.
- This helps prevent foggy windows and musty odors.
2. Prevents Mold and Mildew
- Cars can trap moisture, especially under mats or in the trunk.
- Salt helps limit damp conditions, which reduces the growth of mold, mildew, and bacteria.
3. Easy to Use
- Simply pour ordinary table salt into a small open glass or cup.
- Place it in areas prone to moisture, like the dashboard, cup holders, or floor (away from direct contact with upholstery).
- Replace the salt every few weeks if it clumps from absorbing moisture.
⚠️ Tips
- Don’t spill salt on carpets—it can be corrosive and leave stains.
- For extra moisture absorption, combine salt with a coffee filter or small mesh bag to contain it.
💡 Extra Hack: Adding a few drops of essential oil to the salt can also freshen your car while it absorbs moisture.
