How to Deal with Fog on the Outside of the Car's Windshield?

[DiGavin]

To address fog on the outside of the car's windshield, you can follow these methods: 1. Turn on the car's heater and direct it towards the windshield to reduce the temperature difference between the inside and outside of the glass, preventing condensation and fogging; 2. Open a small gap in the window to allow air circulation, which helps remove moisture and balance the temperature inside and outside the car; 3. Apply a solution of dish soap, soapy water, or saltwater to the windshield and wipe it clean. The windshield is made by sandwiching two layers of glass with a layer of PVC plastic in between, creating a laminated glass structure similar to a sandwich. It is typically designed as a large, curved single-piece unit with specific curvatures on all sides, making both its manufacturing and installation processes highly technical.
