Leaving a car parked outside during the cold winter nights could lead to a frosty windscreen, if not worse like this poor guy found out.
So, if you don’t want to waste energy using a scraper or waste time with that defroster heating up your windscreen, then science has got a quick and cheap solution for you.
The solution is an actual chemistry solution, a mixture of one part water and two parts rubbing alcohol that will dissolve the frost from the windshield rapidly and effortlessly. Isopropyl (rubbing) alcohol has a freezing point of -89°C (-128°F) so the solution not only doesn’t freeze, it actually helps to lower the freezing point of water and melts the frost away.
