Experts at vehicle leasing specialist Cars on Demand say pouring hot water can “crack or shatter” glass within seconds. They warn hot water can also risk heavy damage to a car’s paintwork as the water runs down the side.
The “sudden change in temperature” is to blame for the damage despite many believing this to be the quickest way to clear their vehicles.
Cars on Demand said: “Many think that pouring boiling water on your windscreen is a quick hack to defrost your car after a frosty night.
“Although it may appear to be a brilliant idea it will cost you greatly in repair costs!
“The sudden change in temperature can cause the windscreen to crack or shatter all for the sake of a few more minutes taking the time to defrost your windscreen properly.
“You will also risk damage to your car’s paintwork as the boiling water runs off your windscreen.”
Experts at the AA have also warned drivers run the “real risk of damaging your windscreen” by pouring hot water on their glass.
A recent survey from the group found just two percent of motorists regularly use booking oy water suggesting the majority are aware of the issue.
However, young people were more than twice as likely to use boiling water with one in 20 risking a cracked windscreen.

Experts at the AA warn even warm or lukewarm water can lead to massive damage and urge road users to avoid using it.
They warn glass expands quickly when warm water touches it before contracting quickly when it cools down.
This flexing can lead to even small cracks which can get bigger over time.
However, the AA poll found 23 percent of road users used warm water to clear their windscreen despite this carrying a risk.
Specialists at Holts Auto also confirmed boiling hot water can damage a vehicle’s paintwork.
Hot water can melt the protective wax layer and is likely to leave a white watermark stain.
They warn this can be difficult to remove with road users likely to need the entire car respraying.
Instead of using water, experts at Cars on Demand have urged road users to fill a food bag with water and use this to heat up their windscreen.
This will clear frost and ice cover while preventing the water itself from touching and damaging the glass.
They added: “A quick and effective hack to de-ice your windows, wing mirrors and windscreen is to fill a food bag (or something similar) with warm water and carefully move it across the icy areas of your car and watch the ice melt quickly.
“It is best to use warm water from the tap as it is easier to hold in the bag and prevent the glass from shattering.”However, young people were more than twice as likely to use boiling water with one in 20 risking a cracked windscreen.
