What to Do When the Car Interior is Very Damp?

When the air inside the car is humid, you should turn on the cold air of the air conditioning. The car air conditioning can regulate the temperature inside the cabin and also effectively remove moisture from the cabin. You can place several dehumidifiers or dehumidifying boxes in areas prone to moisture accumulation, such as the cabin or the trunk, and remember to check and replace them regularly. Sunlight contains ultraviolet, infrared, and visible light. The heated car body will quickly expel the accumulated moisture inside.
My old car often faces high humidity issues, and the most annoying thing is the foggy rear windshield after rain. I usually start by checking if the door seals are aged - if water seeps through the door gaps, I replace the rubber strips immediately. Waterlogged floor mats are troublesome; I remove them to dry and temporarily lay some old newspapers as an emergency measure. On sunny days, I quickly open the windows for half an hour to ventilate, and switching the AC to dehumidification mode works even faster. I keep several activated charcoal bags in the car long-term - they're cheap and great for moisture absorption, plus I stash a bag of moisture-absorbing granules in the trunk. Here's a little trick: shake your umbrella dry outside before bringing it into the car to avoid introducing excess moisture. Remember to clean the sunroof drainage holes every quarter, otherwise blockages can cause water to backflow into the car.
