How can this problem be addressed quickly and effectively? Let’s delve deeper into this issue with XE TẢI HÀ NỘI.

Why Does My Car Windshield Fog Up?

A foggy windshield is a common occurrence, happening when there’s a temperature difference between the inside and outside of the car, or due to high humidity. In these conditions, water vapor in the air condenses on the glass surface, forming tiny droplets that obstruct visibility.

Main Causes of Windshield Fogging:

• Temperature Differences: In winter, when the outside temperature is significantly lower than inside the car, warmth from passengers and their breath can cause the windshield to fog up from the inside. Conversely, in summer, when the air conditioning is on, the cold air can cause the outside of the windshield to fog up.
• High Humidity: On rainy or humid days, the increased moisture content in the air leads to condensation on the windshield, causing fogging.
• Deterioration of Nano Coating: Nano coatings repel water, causing it to bead up and roll off, keeping the windshield clear. However, over time, this coating can deteriorate, reducing its effectiveness and making the windshield more prone to fogging.
• Moisture Inside the Car: Leaving wet items like towels or drinks inside the car increases humidity, contributing to windshield fogging.
