Could Moisture Damage Your Car?
Yes.
Persistent moisture inside a vehicle can contribute to unpleasant odors and deterioration of interior materials. Depending on where water is accumulating, prolonged dampness can also create conditions that encourage mold and corrosion.
Writers Resources
Moisture around electrical components is especially concerning.

That’s why a recurring water problem shouldn’t be treated as nothing more than a foggy-window inconvenience.
Salt on the Dashboard? I’d Think Twice
Putting a glass of salt on the dashboard may look clever in a social-media
video, but it’s not where I’d recommend placing it.
Herbs & Spices
The dashboard can experience temperature extremes, and an unsecured glass can move if the car is bumped or moved.
More importantly, the driver needs an unobstructed view and a completely safe cabin.
If you want to test the idea, keep the container in a secure location while the vehicle is parked, and use something designed to minimize the risk of spills.
A Simple Overnight Moisture Routine
If your car feels damp after rainy weather, try this routine instead.
1. Remove wet items
Take out umbrellas, coats, shoes, and anything else holding water.
2. Dry the mats
Remove wet floor mats and dry them thoroughly.
Autos & Vehicles
3. Check the carpet
Run your hand over the carpet and check for hidden dampness.
4. Air out the vehicle
When conditions allow, ventilate the cabin.
5. Use the climate system
If windows fog while driving, use the vehicle’s defrost and ventilation settings.
6. Look for recurring water
If the problem comes back repeatedly, investigate possible leaks.
7. Use a proper moisture absorber if needed
For ongoing mild humidity, a vehicle-safe commercial moisture absorber is a more practical long-term option than an open glass of salt.

Frequently Asked Questions
Does putting a glass of salt in your car really work?
It can absorb some moisture under sufficiently humid conditions, but ordinary table salt has limited capacity. It should not be considered a powerful car dehumidifier.
How much salt should I put in my car?
There is no scientifically established amount of ordinary table salt that will reliably dehumidify a vehicle. If you try the hack, use only a modest amount in a secure container and don’t treat it as a replacement for finding the source of excess moisture.
