Difference Between Fog and Frost on Windshields

Before we start discussing how to defog or defrost a windshield, we must be aware of the difference between fog and frost. The fog looks like steam or white mist inside the car windows. In comparison, the frost looks like ice or crystals on the outside of the windshield in winter. Both fog and frost can block the view. That is why you must know the right way to defrost windshield and get rid of fog on the windshield.

How does fog build up inside car windows?

The fog is like a cloudy mist that builds when the air inside your car is warmer or wetter than the car windshield. When the warm air inside the car hits the cold windows, it turns into tiny water drops. These drops act as a fog and make the windshield blurry, or in other terms, foggy.

The foggy effect will be more if you have applied the tint film. If you have used darker car tint colors or low tint levels, the blurry effect will be high, and vice versa.

Why It Is Important to Defog or Defrost the Windshield

The foggy windshield is dangerous because the drivers can’t see clearly outside. Low visibility on the windshield is very dangerous, and it can lead to serious accidents. That is why you should learn how to defog windshield and increase visibility. Additionally, you should be aware of how to defrost a windshield because frost also reduces visibility similarly to fog.

How to Defog Windshield From Inside the Car (Step-by-Step)

You don’t need the special tools to defog the windshield. All you need to do is use the AC, heater, and some button settings to get rid of fog on the windshield. Here is how you can easily defog a car windshield:

1. Turn on your heater inside your car. This helps warm up the glass.
2. Turn on the A/C even if it is cold inside. The A/C removes moisture from the air.
3. Set the air to blow on the windshield. Use the defog setting (usually a windshield icon).
4. Turn off recirculation. Turning it off will bring in fresh and dry air from outside.
5. If you still feel some humidity, open car windows slightly. This lets the humid air escape.

These steps will help you understand how to get rid of fog on your windshield safely and quickly.

Sometimes, you get fog in the summer, too, but do not worry. Here are some steps to defog a windshield fast in the hot weather:

1. Use the A/C to cool the inside air.
2. Turn off recirculation.
3. Set the fan to blow toward the windshield.
4. Open a window for a short time.

This is an easy way to get rid of fog on the windshield fast without waiting long.

How to Defrost Windshield in the Winter

In the winter season, the ice-like frost sticks to the outside of the car windshield. You can defrost car windows just with the help of the built-in components in your car. Here is how to defrost a windshield without damaging it:

1. Start your car and turn on the heater.
2. Set the airflow to the windshield area.
