How to Defrost Car Windows

Going out to your car at the last minute only to discover frosted and fogged up window glass is not a fun way to start the day. Lucky for you, we’ve got a few tips on how for fighting that fog and frost and getting you back on your way fast.

Why Can’t You Beat this Winter Worry?

Warm air holds more moisture than cold air, thus when temperatures drop, moisture that was easily suspended in warmer air is released, leading to condensation – all those little water droplets fogging up your windshield. Former NASA engineer and YouTube enthusiast Mark Rober has an amazing video explaining this, and the defogging process. As the video explains, to defog the fastest, you have to create the optimal environment to aid the moisture removal process.

1.Turn your heater on.

Start your engine, and using the defroster setting, crank the heater up completely to absorb excess moisture within your vehicle. Remember: Warm air can hold more moisture.

2. Crack your windows.

This helps exchange the humid air in your car with dryer outside air, accelerating the process.

3. Turn air recirculation off.

You need fresh air to enter the car at the same time. Winter air is cold, and as it does not hold much moisture, it is dry. Bringing it into your car ups absorption capacity to more quickly dry the saturated air trapped within.

4. Press the A/C button.

This may sound counterintuitive to the entire heater thing, but really what you’re doing is activating a setting on your car’s A/C system that helps dry the air within the cab faster with the aid of the coils in your A/C system.

Defrost Windows

While this defogging action is occurring, de-frost your windows. This is an entirely separate process that should NEVER (EVER) include hot water. Defrosting quickly takes a minor amount of pre-planning, but saves a snow-capped mountain of a headache later. If you can’t stand scraping, assembled a simple solution of 2/3 cup Isopropyl or rubbing alcohol and 1/3 cup water, pouring the mixture into a spray bottle. This solution will not freeze (rubbing alcohol has a freezing point of 138 degrees below freezing) and may be stored easily in your car, allowing you to easily spray away windshield ice wherever you’re stranded.

Ways to Defog Your Windshield When It’s Raining

1.Switch on your air conditioner.

Pressing the A/C button engages the help of the system’s coils in removing moisture from the air.

2. Turn air recirculation off.

This is the top mistake people make when attempting to rapidly defog windows.

Ways To Defrost Car Windows Without Heat

If you don’t have heat, don’t worry, it’s still possible to defrost your car windows fast with the handy de-icing solution described in Step 5, above.
