How Fog Forms Inside Of Car Windows

Fog can form on the inside of car windows from many sources but they all come down to one thing the relatively warm air inside the vehicle becomes very humid and the moisture in the air turns to fog or frost when it comes in contact with the colder inside surface of the glass.

Of course, the Defrost mode on your climate control system is designed specifically to remove such deposits. But its work is made more difficult and its progress delayed by another button or switch found in most vehicles: the Recirculation, or “Recirc” control.

Recirc Control – Leaving the Recirc control on after initial warmup can cause fogging on the inside of the glass from occupants breath and other moisture sources in the vehicle.

Its purpose is to isolate the interior when driving through extremely dusty or otherwise unhealthy or unpleasant external environments, as well as help accelerate warmup of the interior in winter or cooling down in summer. It does so by closing off the intake of fresh outside air to the heater and A/C system so that it draws air only from inside.

In that way, as the inside air begins to warm up, the heater has warmer air going into it and even warmer air going out. In air-conditioning season, the effect is exactly the reverse: it takes in only inside air that has already been partially cooled, helping the car cool down even quicker.

  • Pour cat litter into the roll which serves as a funnel.
  • Wrap the sock with another sock.

    Car Windows Fogging Up Outside

    When the temperature and moisture level increase outside and are greater than inside the car, moisture will condense on the exterior of the car glass. Similar to the situation when its colder outside than the inside of your car, the goal is to regulate and balance the two.

    • Turn the heat on its maximum setting, because hot air can hold more moisture
    • Then, turn the AC on, which will pull the moisture from the air as it passes over the cooling coils. AC units like the ones at home work like dehumidifiers and pull moisture from the air in the vehicle.
    • Leave Air Recirculation off: its a good idea to turn off your cars recirculation feature to battle foggy windows so the temperature and moisture levels in your car begin to equalize with those outsides. Cold air does not have the capacity to hold water vapor as hot air does. So it will be a little uncomfortable for awhile
    • Let outside air in to balance out your cars temperature. Even if you know its hot outside, but letting the warm air outside come into your car to remedy this problem can be a quick fix. This quick blast of warm air is a lot better than turning your cars heat on during those 90-degree nights.

    How To Properly Remove Moisture From The Windows Inside The Car

    • If its winter, you first need to remove the ice and snow from the windshield and side windows. As long as the ice lies on the glass, it will sweat from the inside, even with the intense blowing of warm air.
    • Then, to clean the windows from fogging, no one should be in the car. Turn on the heater and wait for it to blow warm air.
    • Next, turn off the recirculation if its on, to allow fresh air to flow from outside. By adjusting the air deflectors, try to direct air towards the windows.
    • If it is relatively warm outside and it is raining, moisture is better removed by turning on the AC.
    • At the same time, it is not necessary to warm up the engine, since the temperature of the air blown onto the glass does not have a strong effect in this case.
    • After the windows have been cleaned, you can turn on recirculation so that the windows do not sweat further during the trip. However, increased humidity in the cabin can cause the windows to fog up again. In this case, you need to try other options.
    • Regarding the rear window, things are easy, just turn on the heating.

    When the moisture inside the car comes into contact with the cooler glass surface, condensation forms on the inside. On the other hand, if its warmer outside than it is inside the car, water will condensate on the outside of the glass.

    Either way, driving with poor visibility can be very dangerous, and you should never do that. Whether it happens to fog up inside your car or on the outside, the result is the same.

    Before driving, you need to get rid of the condensation. It will well be worth your time your safety depends on it, after all!

    Use Hot Air With Air Conditioning

    While it may be tempting to get in your car and blast the hot air, this causes immediate heating of the inside of the vehicle, causing the humidity levels to rise and fog to be created.

    Instead, switch on the hot air to warm the vehicle and the air conditioner at the same time.

    The air conditioner will dehumidify the air. This will give you the best of both worlds. A warm car, with a dry, clear window to see through.

    If possible, warming up your car beforehand can help reduce the fogging of windows by allowing more time to get the inside warm.

    And you dont need to worry about being cold because of the air conditioner. You heat will over power your air conditioner so youll have clear windows and a warm car.
