If you want to quickly remove ice, the first thought in many car owners' minds is to pour hot water. After all, ice is solidified or sublimated by cold water or steam, so the easiest way to remove ice is to heat it. Fill a bottle of lukewarm water and pour it directly over the ice.
However, glass does not conduct heat well, and as a result, it will thermally crack. If the thermal expansion of the glass plate during the heating process does not generate heat and damage, there is no problem in pouring boiling water on it. But in case there is a small crack in the glass, and you don't know it, time and time again, the small crack becomes a big crack.
It has been reported before: in January 2018, the owner of the car had ice on the glass, so he poured water on it, and the glass was blown away with a "bang".
But most of the time, it is our own improper operation that leads to some dangerous situations, such as using incorrect glass water. We know that water freezes below 0 degrees, and the same goes for glass water. The composition of ordinary glass water is "water + detergent", so it will freeze when the temperature is lower than 0 degrees. Those car owners who usually use tap water instead of glass water, or are accustomed to using "solid pills", need to pay more attention when the cold wave strikes.
Because the temperature in the engine compartment is relatively high, the water in the glass kettle is not frozen, but once it is sprayed on the cold glass, the glass will freeze and the road will not be clear, so we need to replace the "antifreeze glass" for the car in winter. water".
