do not use hot water
even a drinking glass of hot water can shoot cracks across your windshield. the exterminator at my wifes work last year was from the Caribbean islands his daughert did just this , glass of hot water pop the windshield cracked.
Now some one will call me a horrible fuel waster , the will likely say this as they pull their car from the heated garage that was kept at 50 all night.
I just go out ad start up the vehicles about 15 minutes before it is time to go
dust off just enough snow to get the drivers door open and start and set the defrost to high
10-15 minutes later the snow has kept the heat in and the snow can be pushed off
I am more tempted to get one of these

freezing rain is bad
