Do not let a frosted or fogged window delay you from beginning your day. The defogger in your vehicle can come in handy, but there is a bit more to it than turning on the button. Utilize these tips for using your defogger properly.
The Science Behind Frosted or Fogged Windshields
It is important to know why windshields fog up or are frosting over. The science behind frosted or fogged windshields concerns the air’s temperature. More moisture is held in warmer air. This can cause your window to fog up, especially if your glass is cold. A frozen windshield is the result of the same occurrence, except that the temperature drops. Whatever moisture is in the warm air then turns to tiny water droplets that freeze due to the drop in temperature.
How To Defog Your Windshield
Now, that you understand the science a bit of why your windshield may fog up or frost over, it will help you better remember the steps to clear up your windshield in the early mornings. Aside from pressing the defogger button, you will need to alter the temperature as well. With the defogger on, you need to turn on the heater if it is cold outside. However, if your car is fogged up but it is warm outside, you will need to set the temperature to cool. It is also a good rule of thumb that you make sure the air recirculation mode is off. If you want to quickly defog your window, then turn up the fan speed. Once you can see clearly through your windows, turn everything off.
