Frosted windscreen?

Strider590

The only thing I can say.... While the chanced of damage are admittedly minimal....

The most widely used method for cutting shaped glass is to score it, then rapidly heat it and cool until it breaks along the score line. It's a very clean method for cutting glass without applying a physical force.

Having a basic understanding of thermal dynamics, I would never personally try to use hot water to clear my windows, although 36% of motorists apparently do.

Sure once in a blue moon a windscreen will crack/break and if it does, perhaps change your mind.
Occasionally planes crash, does it stop you flying? With a basic understanding of gravity........

I have a garage, so no frozen windscreens for me in the morning.

ensure the wipers remain on with the water -- otherwise it just refreezes!

Having a basic understanding of aerodynamics I would personally continue to fly

But then...... If I considered the possibility of human error, I'd not leave the house, let alone fly! :rotfl:

I think perhaps I rely on science rather than percentages, Im the first to admit it doesn't always serve me well, but if the chances of death by bungie jump were just 0.5% I still wouldn't do it

I would never advise anyone to use cold/hot or warm water on there windscreen while it is frosted.

You risk causing serious unfix able damage to the windscreen which could resort in a complete windscreen replacement costing £££.

If you use it and have found that it's worked and not cracked/damaged your windscreen, you have got lucky, although small cracks can sometimes go undetected, however if you continue to use water either, cold, hot or warm you risk doing damage to the windscreen.

It is simply not worth the risk, unless you have won the lottery to replace a windscreen every time it's frosty!

What codswallop!

I've been using lukewarm tap water (with a good splash of winter windscreen washer fluid when necessary - helps stop refreezing) for years. My dad has been doing the same for 50-odd years. Guess what neither of us have had a windscreen crack on us due to this.

But of course, you can have it during the day.

Has anyone on this forum ever had a cracked windscreen from pouring hot water onto a frozen windscreen ??

Personally - I scrape with a good screen scraper. Don't like de-icer.

Yes I have. An 02 plate Citroen Picasso when staying at my parent's house. Mother went out in the morning with a kettle of boiling water to de-ice her car windscreen. Thought she was doing me a favour by pouring it over mine as well.

However, unknown to me I had a tiny chip in the windcreen near the bottom. When the hot water hit the windscreen, a large crack formed from the chip. I only found it when I had scraped the solid ice from the screen which had formed when the kettle water had cooled and re-frozen by the time I needed the car.

I always used to scrape the ice from the car with a card type scraper but now I have a Ford Galaxy with heated windscreen so not a problem anymore.

nobby24 can i share too please lol

i use de icer and a scraper and it drives me mad my poor hands get sooo cold,
i have used water in the past and it is a lot quicker and easier but we live down an allyway and the car is at the top so water not always an option as cant leave kids in house on their own or in the car on their own as the engine is running so warm it up a bit. cant wait til we buy a house will defo have to have a drive way
