“A friend recommended it while we were discussing the sudden frost and having to scrape the windscreen.
He told me about demon ice which works well for him.
Went online and read the description. Decided to buy 6 for all the family. I tried it out, spraying the windscreen that evening. True to form, in the morning whilst all the cars around were covered in ice, my Rover had clear windows. No hanging around in the cold scraping anymore. You do need to reapply again in the evening, if not it will ice up.”
