How to remove moisture from the car? Rain in autumn and sub-zero temperatures in winter create increased humidity in the environment, and this moisture also gets into your car and stays there. In summer, sultry, warm air provides increased interior moisture. In the following points, we will show you how to dehumidify your car and what you can do to prevent it.

  1. Avoid wet clothing in the car: Do not get into the car with damp clothing. If possible, wet jackets should be getting placed in the trunk. To prevent the wetness from soaking into the footwell, layout rubber mats and dry them off after the trip.
  2. Check and change car cabin filter: Change the cabin filter at regular intervals. It would help if you changed it every 15,000 to 20,000 kilometers at the latest. An outdated filter will keep moist air inside.
  3. Check car water tank: The water tank is getting located between the windshield and the hood. You should check this area more frequently, especially in the fall. Leaves and dirt can clog the drainage holes, and water will enter the interior.
  4. Use a car interior dehumidifier: A real helper against excessive moisture in the interior is a car dehumidifier. Place the dehumidifier in the interior; water stores in the dehumidifier’s granules.
  5. Don’t forget to air car interior regularly: Regular airing in good, dry weather ensures a significantly reduced interior humidity. It would help if you also allowed your car to air out well after any wet interior cleaning.
  6. Maintain car seals: As a preventative measure, coat your door and sunroof seals with maintenance products. It will make them seal better, and in winter, they won’t stick to the door as quickly when it freezes.

When we forget to clean car drainage channels

Drivers often forget to check and clean the drainage channels for rainwater regularly. As a result, they are often clogged with dirt and leaves, causing water to back up. It is not uncommon to seep into the ventilation system or the footwell.

The only remedy is regular cleaning. The car drainage channels are located between the windshield and the hood, among other places, and they can also be found on the sunroof or at the rear, and it is often sufficient to clean the channels of dirt by hand.

In the case of heavy soiling, a pipe cleaner, for example, can help. Then use a little water to check whether the drain is working again, and it is best to check it regularly to prevent the ducts from becoming clogged in the first place.

Delaying the replacement of the car cabin filter

Change once a year the cabin air filter, also known as the pollen filter. Once the cabin filter is clogged, it can cause moisture in the car, and the caught dust and dirt ensure that the air can no longer circulate optimally.

Also, fungi and bacteria can colonize, making the dirty pollen filter a health risk. That is why it is essential to change the filter. A new filter costs around $16 in accessories and is quick to install yourself. High-quality activated carbon filters filter pollen and dust, and nitrogen oxides from the air.

Drive with closed car ventilation

If the ventilation is permanently closed or set to recirculation, the vehicle is not getting vented. The result; moist air cannot escape! Therefore, turn up the ventilation and switch on the heating because warm air absorbs more moisture than cold air.

It also makes sense to open the windows briefly in between to let the moist air out. It is especially helpful in freezing temperatures when the heating is not warm. The warm air you breathe brings additional moisture into the car and causes the windows to mist up. 

Use the car air conditioner only for cooling

Even if many use the air conditioning only in the summer for cooling, we should also use it regularly in cooler temperatures.

It lubricates seals, prevents bacteria buildup and foul odors, and prevents damage. Besides, the air conditioner removes moisture from the air – and does so much more effectively than the heater and blower.

Do not get into the car with rain-soaked wet clothes

To keep the car permanently dry, we should take off wet clothes before getting in, and we should at least pat-down shoes. Put wet clothes in the trunk to avoid the seats getting wet. If possible, take the damp floor mats out of the car to dry.

If you have a dry parking space in a garage, you can leave the window open. Then the vehicle can air out. Necessary: The garage must also be well ventilated. If there are already damp spots or puddles, the car will hardly dry here.

Do not ignore regular car seal care

Door rubbers and seals are made of rubber, which becomes porous over time and eventually lets moisture into the car.

To prevent this from occurring, you should keep the rubbers supple with the proper care. Products containing deer tallow or unique care products are suitable for this purpose, for example.
