I'll post whatever i like thank you very much, untill someone can convince me that a massive coke can of ipa in five hundred litres of water works in minus four i won't be wasting my money. It's no good coming out with these claims if they don't stand up to reasoning. I agree that it will lower the freezing point of water but not in those quantities.
As for the rest of the year my windows are clean and shiney so why bother to add it? Pure water works or haven't you noticed the gleaming windows it produces?
If you think it works then tell me EXACTLY how such a tiny amount can change the properties of water.
Until now I hadnt read any of the recent IPA threads. But today I was thinking to myself with it being so cold " i will need to check out ipa, to see if it works" but then i thought, well what % will raise the freezing temperature. so I thought I might have to google it or do a test with my freezer and different percentages.
Anyway I dont need to do any tests now, the facts on paper from FTPS link are you need 10% IPA to stop freezing in winter. Well thats a ridiculous amount of IPA. But Im also not silly enough to presume I know it all. Something else could be at play here. Something not quite understood by us as Window Cleaners, so I will be checking it out and if it freezes, then I wont be using it anymore, but I hold my opinion until then, despite the "facts". thank you goodnight!!!
