I asked the same question a year ago, but didn’t get any useful feedback. Maybe the answer is to get a Canadian interior warming system so that ice never forms in the first place.

The condensation of air humidity forming some ice is

very dependent on temperature difference across boundary layer,

wind velocity and number of crystal "seeds" on the windscreen.

(Think of the different kinds of snow!)

For this reasons You can't forecast.

If the water in the atmosphere freezes, forming small crystals, and falls on a cold windscreen, you will get a powdery frost that can be removed with out too much effort. If, however, the water falls as a dew or the car is warm and melts the ice crystals, the result is a windscreen covered in water. As the temperature drops, the water freezes into a hard sheet.

To make your life easier, when you leave your car for the night park the wipers halfway through their sweep and pin one or two sheets of newspaper under them. In the morning remove the newspaper for a nice clear windscreen.

Short answer... no.

I like stewart's suggestion..."park the wipers halfway through their sweep and pin one or two sheets of newspaper under them".

I will be buying a can of defrost spray. It's alcohol and helps with ice on doors and locks too.

I think my girl would be upset if I burn electricity all night in the car with a Canadian warming system. It would be chilly to sleep on the couch alone.

I start the car and go back inside on icy mornings, do you?
