Put a Glass of Salt in Your Car: Here’s Why Some Drivers Try This Simple Trick
Purpose-Made Moisture Absorbers
Reusable automotive dehumidifier bags and other moisture-absorbing products are specifically designed for this job.

Depending on the product, they may contain silica gel or another desiccant and may be designed to be dried and reused.
If your goal is to passively absorb a modest amount of cabin moisture, a purpose-made product is often more convenient because it is enclosed and designed to reduce the chance of spills.
Silica Gel Versus Ordinary Salt
Silica gel is a widely used desiccant. You have probably seen small packets of it inside packaging for electronics, shoes, medications, or other moisture-sensitive products.
Salt
Reusable silica-based dehumidifier bags designed for vehicles can offer a cleaner and more controlled alternative to an open glass of kitchen salt.
Always follow the manufacturer’s directions, especially when regenerating or drying a reusable product.
What About Cat Litter?
Another popular internet suggestion is filling a sock with cat litter and leaving it inside the vehicle.
Some types of litter contain absorbent materials, but performance varies significantly by formulation. Dust can also be undesirable inside the cabin.
Track Atmospheric Data
If you want a passive absorber, a product manufactured specifically for humidity control is generally a more predictable choice.
What About Rice?
Rice is frequently recommended online for virtually every moisture problem, from wet electronics to damp cars.
