How to Defog Your Windshield in Any Weather

How to Defog Your Windshield? How many times have you been in the following scenario? You’re in a real hurry to get to work or drop your kids off at daycare or school. You start your car only to have your windshield fog right up immediately afterwards. You can just sit there and wait for the fog to disappear on its own slowly, but you don’t have that kind of time to waste today. You think about using your hand to clear a spot so you can see, but that will only leave a mess you will have to deal with later.

How to Defog Your Windshield

Luckily, a third and better option is to defog the windshield fast. Use the tips below to clear your windshield quickly and be on your way no matter the weather outside!

Defogging your windshield in the winter

If you’re really rushed for time and don’t mind being a little cold, one fast way to defog windows in the colder months is by bringing the car’s interior temperature closer to the temperature outside. Turn off your heat and roll down your windows to see the fog disappear right before your eyes. You will, of course, be a little cold, but this does work quickly.

When it’s just too cold to open your windows even for just a few minutes, you can turn your defroster on at its highest setting and turn off the air re-circulation. This will allow any moist, fog-causing air trapped inside your car to exit and defog your windshield.

Don’t forget to keep all of your car windows clean, even in the winter. A cleaner window won’t fog up as easily. In addition, you can use an anti-fog cleaner on your window’s interior side to help cut down on fog. Make sure you follow all the instructions on the anti-fog cleaner you choose to get the maximum benefits from the product.

Defogging your windshield in the summer

When it’s warmer outside of your car than inside of it, you will have fog on the outside of the windshield. One way to get rid of this fog fast is by using your wipers, provided they are in good shape and are clean. However, to keep the fog from just coming back shortly after you use the wipers, you’ll want to increase the humidity in the air in the car’s interior. You can do this by turning your air conditioning off and opening your window a little to allow some moisture in from the outside. Once the fog is gone, you can close the windows and enjoy your air conditioning with a defogged window.


As with winter windshield fog, you can reduce fog in the warmer months by cleaning your windows on both sides and using an anti-fog cleaner on the inside of the windows. This helps to prevent the buildup of moisture and oils that can contribute to fogging. Regular cleaning not only improves visibility but also contributes to the overall maintenance of your car.

If your foggy windshield doesn’t seem ever to go away or if you notice some cracks or chips in the windshield, it’s time to call in an experienced professional for replacement or repair. A compromised windshield can be a safety hazard, reducing visibility and the structural integrity of your vehicle in the event of an accident. A professional assessment is crucial because small chips can often be repaired, but larger cracks might require a complete replacement. Moreover, modern windshields are often integrated with sensors and cameras for advanced driver assistance systems (ADAS), and proper recalibration is necessary after windshield repair or replacement to ensure these systems function correctly.
