The first time it happened to me, I was totally stunned I tell you. There I was, driving happily when it started snowing, and when I used my wipers, the glass got all cloudy and so I used the windshield (or wiper) fluid, and guess what! The damn liquid froze on the windshield, despite my having the defroster on at full heat! I had to drive with partial visibility and luckily, since it was Christmas time, the roads weren’t all that busy! Anyway, last week, we went and bought a wiper fluid that stays liquid up to -45 degrees C! Man, the things you encounter when you move to a foreign climate are awesome!
