Can you de-ice a windshield with an impact?
Winter can be a difficult time for drivers. During this icy winter period, driving with ice is not advisable, as the driver does not have sufficient visibility. It is even more dangerous when the windshield is impacted and covered with ice. While it is possible to remove ice from an impacted windshield, it is just very delicate and time consuming.
Why does the windshield freeze in the morning ?
The car windschield freezes in the morning because there is a temperature difference between the air and the windshield. The car is colder than the ambient air. And the moisture in the freezing morning air with the morning dew causes a build-up of micro-droplets of water (at -0°C). It is this accumulation of water that crystallises and gives rise to frost. This phenomenon is triggered as soon as this accumulation comes into contact with the frozen windshield.
