No worries — here’s the quick catch-up so you know what the “glass of salt in your car” trend is actually about:
🚗 The Trend in a Nutshell
People online are sharing a hack that says:
“Put 1 glass of salt in your car — every driver needs to know this!”
It sounds dramatic, but it’s basically about using salt as a cheap moisture absorber.
✔️ What’s real about it
Salt is hygroscopic — it naturally absorbs moisture from the air.
So putting a cup of salt in your car can help:
-
Reduce humidity
-
Prevent foggy windows
-
Minimize condensation
-
Cut mild musty smells
-
Slow mold growth in damp conditions
It’s a budget-friendly dehumidifier, similar to rice or silica gel.
❌ What’s exaggerated
Salt won’t:
-
Instantly dehumidify the whole car
-
Remove strong odors
-
Fix water leaks
-
Replace proper cleaning or repair
It’s useful — but not magical.
🧂 How people actually use it
-
Fill a cup or bowl with salt → place in cupholder or dash
-
Or put salt in a sock/bag → place under seat
-
Replace the salt when it gets damp or clumpy
