alcohol evaporates out the
wiper nozzle slowly

are you saying that alcohol evaporates out of a water-alcohol solution ?

that would mean a beer or glass of wine sitting out would have less alcohol
in it after a while.

if they were serious about the freezing protection of the product, they'd
say what temp it's good down to, one would think.
