Fill a clean jar ¾ full with table salt
Add 1–2 tbsp of uncooked rice (also hygroscopic—helps break up clumps)
Drop in 5–10 drops of tea tree oil (natural antifungal)
Cover the top with cheesecloth or breathable fabric (secure with a rubber band)
Place under seats or in door pockets. Replace monthly.

Important Notes & Safety Tips
Keep container stable: Use a non-tip jar or place in a cup holder to avoid spills.
Not a cure for leaks: If your car is constantly damp, check for sunroof drains, AC condensation, or door seal issues.
Pet-safe: Salt is non-toxic in small amounts (though pets shouldn’t eat it).
Complements—not replaces—cleaning: Vacuum carpets and wipe surfaces regularly for best results.
