kettle of hot water on windscreen

[tigerthecat]

Okay I'm having a discussion with my 18 year old nephew regarding defrosting frozen windscreens with hot water from my kettle. I want to know if anyone really has broken their windscreen as a result of this? I'm always cautious and use half hot and half cold but really is the 'hot water breaks the glass' a myth or what? thanks

i havnt broken a windshield, but i put a glass dish straight from the freezer into hot washing up water and it cracked right down the middle,

You could easily crack it, if not a white frosting will appear at the edge between the two parts of laminated glass your screen is made of.
If you wish to use water, as I do in preference to de icers, only use very luke warm water. You only have to raise the temperature a few degrees above freezing to de frost it.

If your water puddles on the street and then freezes, anybody slipping on that ice may have a claim against you if injured.

I tried this and found it to be a pain - If too hot you can damage the windsreen and if not warm enough it will re-freeze and be even harder to remove.  I just use a scraper.

never use boiling water just turn on hot tap into a bottle just over warm pour onto windscreen keep wipers going untill screen is clear

sorted (has worked for 20 years.)
