you fill a glass and leave it on the dashboard, let’s look at how this hack works, when it might help, how to use it safely, and when you need something more effective.
Why Put Salt in a Car?
The main idea behind this hack is moisture control.
A car’s interior can collect moisture from wet shoes, umbrellas, clothing, snow, rain, condensation, spilled drinks, and even normal breathing when several people are inside.
That moisture can contribute to:
Foggy windows
Damp carpets
Musty smells
Condensation
A generally clammy interior
Salt
