Nothing slows your morning commute like foggy windows, but there are easy ways to stay safe and keep your view clear. As temperatures drop, condensation becomes a common problem for drivers across Vancouver Island. The good news is that with a few simple steps, you can prevent fog from forming on your windshield and windows, keeping your visibility clear and your drive safe.

At Budget Glass, we understand how frustrating it can be to scrape, wipe, and wait for fog to disappear before heading to work. Here are our best tips for managing interior window fog this fall and winter.

1. Use Anti-Fog Treatments or Wipes

Anti-fog products are an easy and effective way to keep your windows clear. Available as sprays, wipes, or gels, these treatments create a thin, invisible layer that prevents moisture from condensing on the glass.

Apply the product to a clean, dry surface and allow it to dry before buffing gently with a soft cloth. You can use these treatments on your windshield, side windows, and mirrors to maintain visibility in any weather. Keeping a small pack of anti-fog wipes in your glove compartment is also handy for quick touch-ups on cold, damp mornings.

2. Keep Interior Surfaces Clean

Dust, oils, and residue on the inside of your windows give moisture more surface area to cling to, making fogging worse. Regularly cleaning your glass helps reduce buildup and improves visibility.

Use an automotive glass cleaner and a microfiber cloth to remove dirt and fingerprints. Avoid household cleaners that contain ammonia, as they can damage window tint or leave streaks. A clean interior also reduces glare from headlights and makes defogging systems more effective.

Pro tip: While you’re at it, give your dashboard and vents a quick dusting too. Clean airways help your ventilation system work more efficiently to reduce moisture.

3. Maintain Proper Climate Control and Ventilation

Most window fog is caused by warm, moist air inside the vehicle meeting the cold surface of your windows. Proper use of your car’s heating and ventilation systems can prevent this.

  • Use your defroster early. Turn on your front and rear defrosters as soon as you start the car to gradually warm the glass.
  • Turn on the air conditioner. It might sound counterintuitive in winter, but A/C helps dehumidify the air inside your vehicle.
  • Set your system to “fresh air” instead of “recirculate.” This brings in drier air from outside, helping moisture escape.
    Remove wet items. Snow-covered boots, damp jackets, or floor mats add humidity inside your car. Keep them dry whenever possible. 

Balancing heat and ventilation goes a long way toward keeping your windows fog-free and your drive safer.

4. Replace or Repair Glass with Damaged Seals

If your windows or windshield fog up frequently despite your best efforts, the problem might be with your window seals. Damaged or worn seals allow moisture to enter the cabin, increasing humidity and causing persistent fogging.

At Budget Glass, we can inspect your vehicle’s glass and seals to identify any issues. Replacing or repairing damaged seals not only prevents fog but also keeps cold air and moisture out, improving comfort and efficiency during the winter months.

Stay Clear and Safe All Season

Driving with foggy windows isn’t just inconvenient; it’s unsafe. With a few easy steps and a little maintenance, you can enjoy clear visibility all season long.
