Rain-X pre-mix washer fluid is good for -20°C. Even diluted 50/50 with water (as it's twice the price of normal fluid), it still works at -5°C
Pros: good for -20°C
Cons: twice the price

Pros: usable in cold weather
My wife just loves the smell of the offical AC Delco washer fluid. I guess it works ok...but she loves the smell so we buy the official stuff.
Pros: pleasant smell, works adequately
They want $25.98 for six gallons of Peak brand washer fluid at Sam's Club! I remember paying half that only five years ago.
Cons: expensive washer fluid
Many people like rain-x. It messes up the sensor in my car (BMW). I find that the cheap generic blue stuff works fine for me.
Pros: works fine, inexpensive
Cons: messes up sensor
Vehicle:
BMW
I just put the orange 2in1 RainX washer fluid in my truck and does this. Ugh.
Cons: causes streaking
I use the rain x stuff but I cut it with filtered water because I have had a history of the rain x stuff clogging my nozzles.
Cons: clogging nozzles
Stop using the Rain-X fluid. It leaves a film/build up on the inside of the reservoir and on the level sensor. You’ll need to pull the sensor and clean it, after that only use the good old blue stuff and you’ll never have the issue again. This happened to me on my 2018 Tiguan and my 2007 Jetta. Rain-X changed the formula for the orange stuff a few years back and that’s when people started having this problem.
Pros: prevents future issues
Cons: leaves film/build up
Vehicle:
Volkswagen Tiguan
I've got a '23 VW. Fluid smells sickenly sweet, like burning antifreeze. I'll be glad when it's gone.
Cons: sickly sweet smell, unpleasant odor
Vehicle:
Volkswagen
