What Causes Ice to Form on the Inside of a Car's Windshield?

[SanRobert]

There are several ways to deal with ice forming on the inside of a car's windshield: 1. Open the windows to reduce the temperature difference between the inside and outside. 2. Turn on the cold air conditioning and direct it towards the windshield. This method removes frost quickly, usually within 20 seconds, but it can be uncomfortable for passengers during winter. 3. Turn on the hot air conditioning and direct it towards the windshield. This method is slower, usually taking more than 2 minutes, but it doesn't cause discomfort in winter. 4. If it snows, clean the windshield thoroughly and cover it with a layer of newspaper. This will prevent ice from forming the next day. 5. During autumn and winter, windows often frost over, obstructing visibility and affecting safety. Therefore, before winter arrives, it's important to check heating devices such as the windshield, side window vents, and rear window defrosters to ensure they are in good working condition.
