Protect wiper nozzles from frost
The next winter is definitely due, even on wiper nozzles.
So, just in time enough I remembered the trick with or against frozen windshield washer nozzles. Chewing gum can really annoy a viewer or viewer, but in this case it's the other way around. Park outside in frost, drive off and close the nozzles. Simply squeeze a chewed soft chewing gum on each nozzle and soothe to bed or anywhere else. A short pluck before the start, ready for spraying.
