Glass does not like a rapid temperature change. In both winter and summer, you should apply lukewarm water to the screen to have the desired effect.

No
Only if heatwave ice has formed on the glass.
Only if the water has miniscule elfs with pick axes who tend to chip away at glass
how would you know Baz?
The latter is unlikely to cause such a level of thermal shock/stress as pouring near boiling water at say 90⁰C on a glass at less than 0⁰C, compared with water at say 10⁰C on glass at 50⁰C.
No, totally different ball game

I doubt the presence of small miners in the water given the current state of the elf service.
what's wrong with wipers washers the water will be the same as outside air for hot weather cleaning, otherwise in winter use a good de-icer spray let the engine run for a few mins (with you in the car) then put demist on
It's the same physics so the same issue, but windscreen washers don't seem to have a reputation for cracking the screen, so I can't see the stresses being the same, even in this weather. I suggest resisting the urge to put loads of ice in the bucket of water, but then not worrying about using it.
