Misty Car Windshield – 7 Tips For Fog Control

March 5th, 2024 by

If you’re like most drivers right now, then the humid summer months can be a bit of a headache. It’s hard to keep everything together between dealing with long commutes & the flailing AC. 


One thing that can often be a challenge is keeping your car windows clear and fog-free. Luckily, you can use some tricks to make this process a bit easier. Check out the Eastern Shore Luxury Cars list of tips below!


Why Are My Car’s Windows Fogging Up?

There are a few reasons why your car windows may be fogging up. The most likely culprit is that the temperature inside your car is different from the temperature outside. When warm air meets cold glass, it condenses and forms water droplets (fog).


Other factors that can contribute to window fog include:

  • Dirty or humid air
  • Leaking or improper ventilation
  • Wax buildup on windows
  • Damaged seals


How Do I Prevent My Windows from Fogging Up?

You can do a few things to prevent your windows from fogging up in the first place.


  1. Adjust the temperature. The best way to prevent your car windows from fogging up is to keep the temperature inside your car consistent with the temperature outside. If it’s too warm outside, crank up the AC just a little in our car. And if it’s chilly outside, keep the heater on low.
  2. Ventilate properly. Make sure that the vents in your vehicle are open and direct air towards the windshield. If you have leaked or damaged seals around your doors or windows, get them fixed as soon as possible.
  3. Keep it clean. Dirty or humid air can contribute to window fog, so try to keep the air in your car clean and dry. If you live in a quite humid climate, you may want to invest in a dehumidifier for your car.
  4. Use defoggers and demisters. Most cars come equipped with a defogging or defrosting feature, so be sure to use it when necessary. Many newer cars also have automatic humidity sensors that will activate the defogger when it detects moisture in the air.
  5. Make your own solution. Suppose you don’t have access to a commercial window cleaner. In that case, you can make your own defogging solution by mixing equal parts of water and vinegar in a spray bottle. Spray the solution on your windshield, and then dry it with a clean cloth.
  6. Keep a microfiber cloth handy. Microfiber is great for cleaning all kinds of things, including your car windshield. If you notice your windshield fogging up, simply wipe it down with a microfiber cloth to remove the moisture.
  7. Park in the sun. The heat from the sun will help to evaporate any moisture on your windshield, preventing it from fogging up. Remember to leave the windows open just a crack for the vapor to leave.
