We have all experienced the annoyance of condensation.

Condensation on car windscreen

You get up in the morning, get ready for work, go out to your car - and oh - find that your car is all foggy. Rather than being ready to set off on time, you’re now left trying to clear your car’s windshield of the condensation that has formed overnight.

But don’t fret. In this article, we’ll take a look at how to clear the condensation inside the car on the windshield.

Here are some quick methods of clearing condensation from your car’s windshield:

  • Giving your car a wash to remove dirt

  • Leave a car condensation absorber on the dashboard

  • Leave the windows open to air out the car

  • Turn on the air  blower and A/C, then wipe down the windows with a microfibre cloth

What causes condensation in a car?

Condensation is caused when the temperature inside the car is different to the temperate outside the car. In most cases, condensation forms overnight, as this is when the temperature outside is lower.

As the cold air outside meets the warmer temperature inside the car on the glass windows, water vapour turns into actual water.

But it’s not the end of the world. There are a number of ways of dealing with condensation on your car’s windows, particularly the windshield.

Clearing condensation from your car’s windows

Using your air blower and A/C

When you get in your car in the morning, simply turn your air blower and A/C on. Set the temperature to cold to begin with and slowly increase it as the condensation begins to clear.

If your car is fitted with one, you can also turn on the windscreen and rear window heater and demister. This will assist in clearing the condensation.

Clean your car windows

Condensation can be a clingy mess. It will cling to dirt particles on the glass. Using a high-quality car window cleaner and a microfibre cloth, simply wipe down the windows inside and out. This will remove any dirt on the windows and reduce the opportunity for moisture in the air to cling to the windows.


Don’t leave wet items in the car

Condensation forms from moisture in the air. As a result, leaving wet items, such as a wet towel, in the car will increase the chances and severity of condensation.

To combat this, make sure to remove any wet items from the car.

Use a car moisture absorber

As mentioned, moisture in the air is one of the factors in causing condensation. A car moisture absorber works to remove this moisture from the air.

Car moisture absorbers can be purchased at most major supermarkets.

If you would rather not purchase a moisture absorber, an alternative method is to leave the windows open when it’s dry. This will offer similar benefits and help to clear the condensation.

Following these steps should help clear the condensation in your car, as well as reduce the severity of the problem. Now you can get back to your normal morning routine and not have to leave an extra 20 minutes early just to clear the condensation!
