What to Do When the Car Interior is Too Humid?
3 Answers
When the air inside the car is humid, you should turn on the cold air conditioning. The car's air conditioning can regulate the temperature inside the cabin and effectively remove moisture from the interior. It is best to go to a professional car detailing shop for an interior cleaning. Using high-temperature disinfection methods such as steam, ultraviolet light, and photocatalysis, the car's interior can be kept dry and clean. To prevent the car from developing "rheumatism," the owner can place several dehumidifiers or moisture-absorbing boxes in areas prone to accumulating moisture, such as the cabin or the trunk.
Last time during the humid season, my car mirrors fogged up, but I found a few handy tricks that really work: Leaving the windows slightly cracked for ventilation after parking is the most practical solution. If it's rainy, buying a dehumidifier box and placing it under the seat can collect a full box of water in just a week. I also tried reusing food desiccants by stuffing them into the door panel storage compartments. In summer, remember to use the external air circulation to defog the windows when running the AC, and in winter, use the heater for dehumidification while pressing the AC button to activate the compressor. Laying diatomite floor mats in the car can absorb moisture, and placing bamboo charcoal bags in the corners of the trunk can also eliminate odors. After washing the car, always dry the water accumulated in the seals to prevent mold from growing quickly. If all else fails, there's a magic solution—hanging bentonite cat litter wrapped in stockings from the headrest, which is much cheaper than professional dehumidifiers.
As a long-haul driver, I dread interior humidity the most. Once even my dashboard grew mold. I recommend getting a cigarette lighter dehumidifier – just plug it in to use. During rainy seasons, remember to set your AC to front defrost mode and turn on the rearview mirror heating. Here's a handy tip: shake your umbrella a few times before getting in the car on rainy days, and never leave wet umbrellas inside. Replace aging window seals immediately – you can get them on Taobao for just tens of yuan. If floor mats get soaked, removing them for sun drying works better than using hot air. Change AC filters regularly, and avoid using external circulation on humid days as it worsens moisture. Applying anti-fog film to the sunshade's interior side reduces fogging by 50% when parked – tested and proven.
