I live in Wisconsin and there is plenty of snow and ice.

I finally figured out that the only way to deal with clearing the
windshield is to simply go out, start the car and turn on the
defroster full blast.


Then do the shoveling and by the time I'm done, the windows are all
clear.

Now that I'm retired nothing has got to be done in a hurry.

An extension cord and a cheap electric heater/fan does that job very well.
