Like others, I've only used water for defrosting for at least 30
years, no issues with cracking.

"I".

You may well have 'got away with it' for 30 years but I wouldn't do it.

So would you rely on de-icer, a scraper and the car heater left on for
ages?

Erm no.

As I 'said' before ,
I remove loose/surface snow with a scraper .

Spray with Iso-propyl.(have gallons of it to clean my (bicycle)
brakes(Hydraulic disc).

If needed, I give a quick 'bloop' to the windscreen wipers whilst
activating the screen wash.

The rear screen is heated I can usually see out the back anyway but
the heater ensures I have a clear view by the time I am out of the cul-
de-sac's car park.



That brings me too a side point how do heated windscreens work?
I fully realise rear windows have wires in them but I have never seen a
windscreen with wires yet I have seen cars specced with heated
windscreens.
