Which of these mixtures is NOT suitable to use as wiper fluid?

While water/diy water mixtures can be used as wiper fluid in a pinch, it isn't recommended. Water freezes in cold weather and when left stagnant, serves as a breeding ground for harmful bacteria. When in doubt, over the counter windshield wiper fluid works best and please, don't ever try orange juice!
