Windex Auto -40┬║ Windshield Wash
Works well, but not great
I purchased this because the Rain-X De-icer that I normally buy was all sold out.
I did not have any issues with the fluid freezing with temperatures below -20C, even with a cold car and it left a nice streak free windshield.
My issue was that it left a blue residue all over my car. You could see a trail of blue from the parts of the windshield that my wipers do not touch, all the way to the back window.
Performance wise I do like this product, but the blue residue that it left all over my car has prevented me from buying it again. I will stick to the Rain-X brand, which I have been using since 2008.

Not suitable for winter
I don't know where Windex gets the stated -40┬║C rating because this fluid freezes on contact with my windshield at any temperatures below -5┬║C. When I spray it on my windshield, it will initially melt a bit of frost but within seconds it freezes across my entire windshield, obstructing my view. I need to keep re-applying it until my windshield warms up from the inside, which is a waste of fluid. This product definitely does not deliver as a winter washer fluid.
When my windshield eventually warms up, however, it cleans the glass well and doesn't leave streaks. Therefore, I might purchase this brand again in March when the temperatures are warmer.
Bottom line: don't waste your time with this fluid for winter weather. I'll be sticking with Rain-X De-Icer fluid.

I wasn't having much luck with some brand new Rain-X wipers on my GMC Terrain until I tried this washer fluid.
I tried Generic -35 and even some Rain-X De-Icer fluid before and it was causing streaks and the window didn't seem clean. I figured I'd try Windex before tossing the wiper blades and lo and behold it worked really well! The windshield isn't just free of ice, but it's clean.
The only downside is the price. I've also wondered if the formula would cause issues with the plastics of the hood... but so far no issues.
