Fogged up car windows and windshields are no joke; they’re one of the most frustrating—and dangerous—situations that drivers across Canada face during winters.

During the winter, your car’s windows are typically hot from the inside due to the heater in your car. When chilly winds come in contact with the outer glass, the vapour condenses. The resulting fog doesn’t just obstruct the driver’s vision, but is also a major cause of accidents in Canada.

In this blog, we’ve rounded up some steps to help you keep fog at bay.

Step One: Turn on the Heater

If your car windows are fogging up, your first step should be to turn the heater on—stick with us, we know this sounds counterintuitive. Hot air tends to absorb and hold moisture, which will be important in the next step.

But make sure to not turn it to its maximum setting immediately. The sudden shift in temperatures can lead to rapid expansion and contraction in the glass molecules that might result in a cracked window or windshield.

Step Two: Turn on the AC

After a while, turn off the heater and turn on the air conditioning. This will help eliminate the leftover moisture in your car.

Since the temperature inside your car is still high because of the heater, don’t turn on the air conditioner on full swing, as it may damage the glass.

Step 3: Open Your Windows a Little

If the air conditioner in your car is malfunctioning, you can roll down your windows a bit to let the cold air inside your car. The air inside your car is more humid than the air outside, and replacing it with dry air from outside will speed up the process of defogging your windows.

Some Preventive Measures to Keep the Fog at Bay

Now that you’re aware of some quick ways to defog your car windows, here’s how you can stop your windows from fogging up in the first place. Get proactive!

  • Clean your glass using an alcohol-based, ammonia-free auto glass cleaning solution and a soft piece of towel.
  • Spray the glass with an alcohol-based oil removal solution, to degrease the windows and let it sit for 2–3 minutes.
  • Clean the solution off the windows using a moist micro-fibre towel. After the degreasing solution is thoroughly cleaned, apply the anti-fogging compound on the inside of your windows and windshield. Do not spray the compound directly on the glass, spray it first on the applicator (provided with the anti-fog solution), and then wipe the glass with this applicator—first, vertically, then horizontally.
  • Read the instructions on the manual provided with the anti-fog solution, and let it sit for 3 to 5 minutes, or longer if the manual says so.
  • When done, wipe the inside of your windshield and car windows with a clean, dry piece of cloth.
