free window cleaning info: How cold it has to be for alcohol to freeze
Question:
Sue
thanks for the info. but wondering how cold it has to be for alcohol to freeze, it gets pretty damn cold up in Canada in the winter.
Answer:
Pure ethanol freezes at -114 °C …. But cleaning with it will do more harm than good. I use windshield wiper wash. It’s good till -20°F and you can add some dish soap to it to help clean. Alcohol will break down the dish soap and make cleaning a mess.
When the windshield wiper fluied freezees then you know it’s time to go home.
