Surprising Hack Every Driver Needs to Know

The claim that “putting 1 glass of salt in your car” is a life-saving driver hack has gone viral on social media (especially Facebook), often accompanied by dramatic headlines like “A police officer taught me this when I got pulled over!”
However, there is no credible evidence or scientific basis for this advice—and it may actually be harmful.
❌ What the Viral Hack Claims (And Why It’s Misleading)
Posts suggest keeping a glass of table salt in your car will:
Absorb moisture and prevent foggy windows
Neutralize odors
“Dry out” a wet interior
Even act as an emergency traction aid
But these claims don’t hold up:
A single glass of salt cannot meaningfully dehumidify a car’s cabin—commercial desiccants (like silica gel packs) are far more effective.
Salt won’t help with traction if you’re stuck—it needs to be spread under tires, not sitting in a cup.
Open salt attracts moisture (it’s hygroscopic), potentially creating a damp, corrosive mess on your dashboard.
