TIL my windshield wipers were the reason my wiper fluid froze in Des Moines
The reservoir was fine at 10 degrees but the nozzles kept icing over because I put the 0 degree fluid in back in November, has anyone swapped to heated washer lines or is there a better winter mix?
Man, that's a classic winter headache right there. I've been there myself and honestly the cheap fix is just buying the -20 or -30 fluid for the whole season, don't mess with the heated lines unless you got money to burn. The warmer fluid might help a bit but it doesn't fix the nozzle itself freezing up, so I just carry a small spray bottle of deicer in the truck for mornings like that.
