I regularly see people scraping windows in the freezing cold and wonder why they do it I have used a pop bottle full of warm (not hot) water for years and have never cracked a window, if you dribble it slowly over the windscreen once its clear it puts enough heat into the glass to stop it freezing again and allows you to drive off straight away.
