What causes car windows to steam up?

Before getting to the main part, we would like to walk you through the cause of the fog problem as we all know that the root of the issue will lead us to figure out effective solutions to prevent your car windows from fogging up in winter. To answer this question we will talk about condensation.

When water vapour hits something cold, it changes from the gas form into the liquid form. In this case, the warm and moist air inside your car hits your windows that are colder and turns into tiny water droplets.

It’s the same thing that happens to your bathroom mirror when you have a shower with hot water on cold days, or when you breathe on a window to draw a smiley face.

If you use a cotton rag to clean up on your froggy glass or windows, you’re not doing anything to address the moisture issue.

You will only have a clear vision in a short amount of time until the fog comes back unless you make some changes to the car’s environment.

To solve the problem I recommend you apply following ways to demist your windows:

  1. Keep a clean windshield

The first method you can apply to stop car windows from fogging up in winter is to keep your windshield clean, especially on the inside. If you don’t clean the inside of your windshield regularly, dirt on the inside of your window gives ground for moisture to stick to it, thus creating that annoying fog on your window.

So all you need to do is clean it by using some drops of glass cleaner with a cotton rag.

  1. Warm up your engine

The next effective method you can easily practice is to crank your car engine up. In winter, your car always gets full of fog.

If you only clean it with a few drops of glass cleaner, it’s only a temporary solution. That’s why it’s highly recommended that right after opening the car door you should start the engine to warm up the inside and combine with cleaning the inside of the windshield, rearview mirrors, windows.

The next step is to turn your car or truck’s heater on to warm windows during cold weather and prevent dew from forming. It’s also a good idea to use the windshield heat function but not the recirculation function due to the fact that recirculation will push the dewy air through the car, which will make the fog come back and condensate on your windows.

  1. Turn on your air conditioner

Turning on your air conditioner is also a good way to get rid of fog staying on your window on crispy days in wintertime.To apply this technique successfully you should follow these steps.

First, you should turn the heat on to its maximum setting, because hot air can hold more moisture.

Then, you turn the AC on, which will pull the moisture from the air as it passes over the cooling coils.

Finally, you turn off the recirculation button so that colder, dryer air is brought into the car.

If possible, you should put your windows down for a couple of minutes to help exchange the humid interior air with the dryer air outside.

During hot weather, or just in areas where there is humidity umpteen in the air, turning the A/C on high can dry out the moisture that leads to window fog.

It’s advisable that you should let it run before you drive away to dry out the moisture. Then you can turn it off if you want as you don’t have to freeze the entire drive.

  1. Open the car windows

Another useful tip on how to stop your car from fogging up in winter is to put your windows down.

Just crack your car windows open slightly for a few minutes. This will help combine the humid air inside your car and the cold and dry air outside your vehicle to remove fog from your windshield.

You should open the car windows for a few minutes, so that the air circulation and the temperature inside and outside the car are equal.

  1. Keep Moisture Out of Your Car

Keeping moisture away from your car is another tip we advise you to follow. In winter, the weather is always wet, especially on snowy days.

As soon as you step out of the door, the snow will cover you, clinging to your clothes, your hats, your shoes and they will follow you into the car and this will increase the humidity in the car, which is not good for removing fog from the car windows.

If this ever happens to you like what we have mentioned above, make sure that you take off your wet clothes, hats or shoes before you get into your car.

  1. Use anti – fog products

The last method to stop car windows from fogging up in winter that we would like to recommend is to use anti-fog products. Anti-fog products will provide a coat for your windows so that no moisture can cling to them and they also make it less likely for dust and oil to accumulate.

When applying these products, make sure to use lint-free rags to apply it evenly. You may also need to wipe the coating layer down the next day, once the product has settled into the glass. One more word, you should leave your car doors open while these anti-fog are sprayed as the fumes can be intense and make you feel hard to breathe sometimes.

In summary:

As you know in winter the phenomenon of fog covering your car windows is normal, if you don’t want to be late for work because you have to struggle to remove the fog from the car glasses, get up early, leave the house 10 minutes earlier, you take that amount of time to solve the problem by applying our tips on how to stop car windows from fogging up in winter so you will not feel uncomfortable but you will have a pleasant start to the day.
