Does the car glass have snow and ice, and will the plastic PP board scratch the glass?
It doesn't scratch the glass. But it's a lot of trouble, especially the edges of the glass. It's very easy to hurt the paint. It seriously causes the metal corrosion of the car body. It's very troublesome to handle.
You can turn on the engine, turn on the hot air, select the windshield heater, and after a few minutes you can easily remove the ice and snow. No hot water can be used to remove ice, which can easily cause glass to burst!
