And for anyone with respiratory sensitivities — especially older adults — reducing mold exposure can make a real difference. Breathing cleaner air while you drive isn’t just a matter of comfort; it’s a matter of health.
A Simple Fix That Costs Pennies
In a world of pricey dehumidifiers and chemical odor removers, the beauty of salt is in its simplicity. You don’t need batteries. You don’t need filters. You don’t even need instructions.
- Grab a small container — a mason jar, a bowl, or even a coffee mug will do.
- Fill it with plain, dry table salt (rock salt or sea salt work too).
- Place it on the dashboard, in a cup holder, or under a seat.
- Replace it every few weeks or when the salt becomes damp and clumpy.
That’s it. No setup. No tools. Just a natural way to control humidity inside your car and enjoy a more pleasant driving experience.
Salt vs. Other DIY Dehumidifiers
While salt is an excellent moisture absorber, it’s not the only one. You might also consider:
- Crumpled newspaper: Cheap and absorbent, though not very long-lasting.
- Charcoal briquettes: Good for odor control but can be messy.
- Silica gel packets: Found in packaging — very effective, but not always easy to come by in bulk.
- Baking soda: Great for odors, slightly less effective than salt for moisture control.
Salt hits the sweet spot — it’s affordable, highly effective, and widely available.
