You could hold your breath a really long time. That’s one way to keep your windshield from fogging up on the inside when you leave your Johnsburg home. Of course, how long can you really hold your breath?

In the winter, the problem is that it’s warmer inside your car than outside. If there is significant humidity inside the car, that moisture can collect on the car’s windows. Breathing pumps moisture into the cabin atmosphere. Of course, other things will add to the moisture content in your car.

Snow on your clothes can evaporate into the air and collect on the windows. Even running the heater can add humidity that can fog your windshield and windows.

However the moisture gets there, it’s annoying and, potentially, dangerous to have foggy windows and a foggy windshield. So, what can you do about it? You scrape your windows in your Johnsburg driveway and head out on the road with everything clear. Suddenly, the fog begins to appear on the inside of the windshield. What are you to do?

Here are some tips on how to deal with a windshield that fogs up on the inside:

• You can carry a cloth to dry the windows and/or a squeegee. The problem with these options is that they tend to leave the window badly streaked when it dries.
• You can neutralize the temperature in your car (i.e., allow the temperature inside the car to equal the temperature outside of the car. This, of course, requires a sacrifice on your side – Johnsburg winters can be bitterly cold and who wants to drive around shivering?
• You can turn on the air conditioning for a little while. The AC tends to dry the air. This will help but, of course, it will also give you the chills.
• Turn on your defrosters but don’t use the recirculation option. The recirculation option is where the heater heats air from inside the car. Since the air is already warm, it’s easier to get the air warmer. This will work but the inside of your car won’t warm as quickly.

Thankfully, some cars run the AC compressor when you turn on the defrosters. This way, the AC compressor is helping to dry the windshield while the defrosters are blowing warm air on the windshield.
