Morning dew and fog
Breath and body heat (yes, you add moisture!)
Spills, pet accidents, or forgotten water bottles
That trapped moisture:
âś… Causes foggy windows (especially in fall, winter, and spring)
âś… Feeds mold and mildew in carpets and upholstery
✅ Creates that persistent “old car” smell no air freshener can fix
🌫️ Fog forms when warm, moist air hits cold glass—and your car’s cabin is a fog factory in humid or cold weather.
