When you leave an open container of salt in your car:
It pulls water vapor out of the air
Reduces overall humidity
Prevents condensation on cold surfaces (like glass)
Helps stop musty smells before they start
Think of it as a passive dehumidifier — no batteries, no noise, no cost.
🔬 Bonus: Unlike silica gel or commercial packs, salt doesn’t saturate quickly — it keeps working until it clumps or dissolves.
