The warnings came from the old windscreens, the early tempered and plain ones. They DO shatter when you put boiling water on them! The modern laminated ones are rather better at withstanding the temperature shock but, as you say, warm water that isn't boiling is the safest way. Also be careful if you've had a replacement windscreen that was a pattern part, not genuine. Some have a very thin layer of top glass that chips easily and is most likely more prone to cracking with the temperature shock.

I simply ask them "Do you know OF anyone that that has actually happened to??", and they never actually do!

No Ian, it can ruin screens. Not crack them but what happened in one of my cars was using very hot water the windscreen laminate began to go milky between the glass. It took a few days to make this obvious and then it was too late. New windscreen. From now on my usual method is get in, run engine, and sit and wait. It took today [-3°c] 12 minutes from getting in to driving off and having warm air coming through the vents to defrost the windscreen. Side windows [passenger and driver] too. This period of time also enabled the engine to begin warming before setting off - along with hydraulic fluids etc. I don’t mind 12 minutes sat with warm seats [heated] rather than staying wrapped up walking in and out of the house with water, or scrapping the ice off [getting ice on jacket, which duly melts making jacket wet]. Patience. It’s all you need.

Coming from the wilds of Kent, I was sometimes able to thaw out frozen door locks with body-temperature water from nature's reservoir. Then, sixty years ago, living in an isolated location, the risk of being observed and ending up as a byline in the Sunday papers was minuscule. Being a smallish chap, in my floriat, I was only 5' 9" in thick socks, this dodge worked on small cars like my 1960 Mini. Larger cars would have posed a problem, as the ballistics of delivery would have necessitated stepping back from the door, increasing the chances of attracting attention to my nefarious activity. As far as windscreens are concerned, I have used a washing-up bowl of luke-warm water, drawn from both the cold and hot taps, without incident since Macmillan was the prime minister! The water does not need to be near boiling point, just significantly warmer than the freezing.

As others have commented, the problem was probably connected to the use of toughened windscreens which were far more prone to shattering. In the '70's I was driving a Ford lorry on an extremely cold day. I left Bournemouth with a cold engine which had warmed up by the time I reached Ringwood. I turned the heater on to keep the screen clear and within seconds the screen shattered and blew in all over me. Most uncomfortable especially as I was wearing wellington boots and the shards of glass went down inside them.

Well, there you go. Never done that. Like the rest of the internet, I thought it would break the window - especially on my classics. However, I am glad to see the practical application worked perfectly and will keep it in mind. We still get ice on the windscreen in Auckland, NZ midwinter, but the garden hose is usually enough to soften it and loosen the wipers up to clear the rest. There was one morning that driving down the road with the wipers going, the windscreen started icing up again (the ambient temp was zero degrees Celsius, so the wind chill would have been colder), but a shot of Bars Bugs from the windscreen washers cleared that off. I guess in other parts of the country (and indeed the world) where the weather overnight will freeze the water in the hose and put more than a few millimetres of ice plus frosting on the screen that warm water could be the saving grace. Again, many thanks!

Thanks Ian. I've been pouring warm water onto windscreens since 1981, and never had a breakage, even though some of them had stone chips. But I've never used anything warmer than about 'elbow hot' or hot tap water; about 55°C. On several occasions, the air temperature was around -20°C, but still no problems. As a matter of course I used to take a couple of 5 litre bottles of hot water, wrapped up in car blankets, on long journeys when working. These had two functions, as needed; warming the cabin and/or occupant at the end of a long day with the car standing, empty, and defrosting the windscreens before returning home. I've almost never bought de-icer, and rarely use a scraper. In the mornings, I'd hear people scratting away at their windscreens, while I'd go outside with a pan or kettle of water, pour it onto the screens, start the wipers, put the kettle back into the house, and drive away while the neighbours were still spraying and scraping. The dire warnings from those neighbours about broken windscreens were never fulfilled.

I've found that if you have a chip that already has radial cracks coming out of it, you then risk the cracks expanding outwards if you pour boiling water on that area. But you can destress the window first by pouring the boiling water on the opposite side of the windscreen. I would imagine that to get a laminated screen to crack you would need to hurl a bucket of boiling water all over the screen at once and hope the glass near the bonding to the body doesn't expand as quickly as the rest of the glass.

It may be that this was once true when windscreens were rather more primitive, and the "knowledge" has been passed down unchanged. Other examples include never crossing your hands on the steering wheel, which was important in the very early days when hand throttles were the norm, and blipping the throttle when turning the ignition off, originally to get some petrol onto the spark plug to avoid condensation forming on it thus making the next day's work with the starting handle hopefully rather easier.

The size of the windscreen was no different in size to the one in this video, yet it only had one wiper. Rather than the usual 90-odd degrees arcing movement that wipers normally make, this single particularly large wiper made what I can only describe as an "M" shaped movement of 180 degrees across the entire windscreen. Presumably, there was some clever cam as a part of the wiper motor but it was always interesting to watch! I can't say I've seen anything like it before or since, but I'm sure they exist elsewhere.

I had a rear window shatter in very cold weather when I turned the rear window heater on. It's quicker to use a scraper rather than waiting for a kettle to boil.

I use a watering can of warm water from the hot water tap underneath my combiboiler, so by the time I get to my car maybe 45-50°C. I start up the car, put on the rear-window and mirror defrost and all the lights, clear the windshield with warm water, put the wipers on, and then use the rest of the can to clear the sidewindows. I wouldn't risk using boiling water, even if it doesn't harm the windows, it can't be good for the paint and window rubbers.

Heres a question how do you prevent ice forming inside your windscreen especially when you own a Spanish car that seems to dislike the cold (which is does)

never tried with boiling water before, but our hot water heater makes it come out of the tap literally steaming hot so its probably around the same tempature, assuming whatever pot of water you’re using is boiled inside, and carried to the vehicle a small distance, the cold air would cool it rather significantly id think, but of course thats what this video is for!

Domestic hot water only tends to be around 50 degrees or so, but will still steam. The first take here used water that had cooled a little. The second take (the first one you see) was much closer to boiling.

I was a work shop manager at a large Rover, Land Rover, Range Rover, Triumph, Vauxhall dealer ship in the 70's. All cars straight from factory were covered in wax protection which required steam cleaning (very hot) 🥵 to melt wax. Both Laminated & Toughened glass went through the same process, hundreds of times, never once did a glass break. The cars would be brought out of compound in depths of winter & be subject to hot blast of steam cleaning before being dispatched to my workshop for PDI. As I said not one cracked. Now whether or not today's glass is not up to the strength of the earlier glass I couldn't say. That's for you to decide, me, it's never gone wrong.

I suspect that boiling water on a zone-toughened screen might cause a failure, but modern laminated windows seem to have no issues at all.

Boiling water will not crack modern screens, however much better to use tepid water as will not refreeeze as quick ( don’t know why). Also a tsp of salt in watering can full of tepid water works for me and been driving for 47 yrs. also wont get pooling on floor if pouring volume is slow. Bear in mind the front screen defrost will prob freeze tiny washer holes so concentrate on them too

Oh that salt!!! If you use it on door windows the drain holes are almost always blocked. The bottom of doors is a common rust trap. Not sure I would help it along. Also the windscreen scuttle panel and under the windscreen rubbers are rust traps as well. The salt could even get into the top inside of the hinge panel/wing. I would expect bubbling in the paint.

I always used to avoid doing this because of the scaremongering but with 2 young children I haven't got time to fanny around so started using warm water from the tap and won't be going back, if a modern windscreen can't cope with some warm water being poured on it then there's no hope.

Just ti be safe and because most of the cars I've had have had chipped windshields (gravel roads and Patagonian winds) even tough those chips were fixed, I found pouring ethilic al alcohol the most efective way of de-icing my windshield, and you also avoid the risk of ice forming under the car as it melts.

Re the comments about old style toughened windscreens vs newer ones being laminated; aren’t side and rear windows still of the toughened glass variety? They still shatter in the same manner as the old toughened windscreens do. Ian poured onto those as well. As a side note, two years ago I turned on my heated rear screen on a 2012 Accent I had at the time and all was well but when I turned it off 10 mins into my journey - the rear screen shattered! Stayed together so I was able to tape it up but that was a new one on me. It was about -15c at the time and no other cars to have coincidentally kicked up a rock (4:30am drive to work) - very strange.

I too use hand hot water, but in a zip-lock bag which I drape across the glass, effectively wiping away the ice. 1litre of warm water, thus contained is enough for the windscreen & side windows. When done, I then empty the now luke warm water onto the screen & wipers, so that they too are de-frosted. All of the above warms the glass sufficiently that it doesn't fog up when you get in & start breathing on it. Been using this method for decades without issue. One point to note, if it's really cold, say < -5C, it's best to use the wipers asap to clear water from the screen before it can re-freeze.

Tepid water works just fine - been doing it for decades with no issue. I wouldn't use hot as you do stand the chance of breaking the glass by thermal shock, albeit if the risk is quite a small one.

I still see a lot of cars around here with cracks caused by boiling water. This could because our winter nights can get in the -30°c range. I think warm water, ie 40°c is ok though.

I remember my dad used to do this when I was a kid. I'd sit inside whist he poured boiling water on the toughened (pre-laminate) windscreen. Nothing bad ever happened that I remember, although I do clearly remember the day a stone from a passing car broke the same entire windscreen and my parents had to punch a hole in the glass to see where to drive.

possibly if it gets into the laminate of the screen through an existing stone chip wound and expands out fast re freezing .. if screen is perfect its ok with warm water just get a nice pretty pattern 5 minutes later thats all.

I guess it's pretty unlikely for a windscreen to crack from doing this, but winter here in the very northern parts of Europe can still be dangerous to windscreens. Probably not so much because of the temperatures, but because they're using sand/gravel on the roads and the little stones stick really well to the tiny slits found in winter tyres. Naturally they'll fly off as you approach motorway speeds and usually find their way into the windscreens of people driving behind. And I guess there's the occasional metal stud from a studded tyre flying around, too. Yet another reason to keep a safe distance!

2 litre pop bottle filed from the hot tap. if it's not too hot to hold it's OK; keep it moving while pouring all over the glass, it's just the right delivery rate
