De-icing a car windscreen using hot water in a bag method

[Hosoan]

Has anyone used this method to de-ice a car windscreen, where you use a plastic bag of hot or warm water and move it over the windscreen to melt the ice?
If so has anyone experienced cracking of the windscreen? I know it's a risk but am not sure how much of a risk.
I am aware not to just pour water over as it can freeze on the ground making it slippery, but using a bag avoids that.
Any experiences please

You lot are crazy.

£10 buys you a screen guard from amazon which you put in at night and take off in the morning.

It takes 1 min or less to put it on at night and 30 seconds to take it off in the morning, No messing about with hot water bottles and frozen fingers. Completely clear windscreen, no frostbite. Every time,

@IfIwasabluebird Are you in the uk? Always thought it would be a good idea to turn the street lights down at night for environmental reasons. (I know it may cause other issues too)

Exactly - I leave home at 6am, no way am I going to be bothered to start scraping the windscreen at that time of day!

I just switch on the car for 10 minutes before leaving, it's completely defrosted and warm inside!

Never ever use hot water.

I use an empty milk carton and fill it with room temp/warm water and pour it over.

I take it in with me when I finish work and take it out in the morning.
If it gets icy when I’m at work then it’s there to fill up if I need it.

Definitely going to invest in a windscreen cover.

I have also done this, warm water in a bowl. The danger is if it's hot water

I was probably unlucky (and goodness knows how much water they must have used) but in my case the ice covered the entirety of the pavement between the drive and a main road. Walking in a main road isn't doable for obvious reasons and there was no way of avoiding the sheet of ice. I guess if you think how much water spreads out if you drop a glass, if they chucked a jugful over the car that has the potential to spread quite substantially.

My next car will probably be an EV - all my colleagues have them and they just start the heating remotely 10 mins before they need to leave. One of them was telling me how nice it is when you’re skiing, and you can start warming your car while you’re skiing down the last run of the day.

If you use a windscreen cover, where do you leave it when you take it off and what do you do to clear the other windows? Or do you only look forwards when you drive?!

Mine covers the entire top half of the car , so all windows and has "ears" that go over the wing mirrors.
I just put it in the boot, shake off snow first.

Like this but nicer and with tabs that lock it into place once the doors are closed
Open the doors and whip it off !

Yes. I've complained about the lights being turned down as its risky for pedestrians & cyclists (active healthy travel). The council need to save money so won't turn them up.
It's not good for the environment if people need choose to drive / taxi more.

Yes, I used to pour warm water on to de-ice and it works well - until it freezes again,

Now I use a scraper. But the cars are next to a fence so we generally only have to do one window and the windscreen, the rest doesn't freeze.

Good point.

People plug their cars in, or store them in a garage.

I have a sheet that goes over the windscreen, it's got ears that you trap in the door to hold it in place.

From the mains via an extension lead plugged into an outside socket.
