What's The Quickest Way To De-Mist A Windscreen?

The Martian movie is nowhere near as good as the book. It was dumbed down so much it hurts intelligent people. Skip the movie, read the book.

“Turn on your AC”

Welp.

Cut a potato in half and wipe it on the inside of your windows. It does work. http://lifehacker.com/5485831/keep-car-windows-from-fogging-with-a-potato

Oh. This was already posted. Guess I’ll remove my repost haha.

Or can just use a big towel aaaand….

in canada , that mist freezes , i carry a used gift card and scrape it off

I’m a little confused about something here (seriously), and would like some clarification. 2002 honda civic with A/C. From what I understand the A/C is just a cooler and the heater is just blowing hot air heated by going through the engine bay to the cab.

So why do you turn the heater on full blast and the A/C on? From what I understand, when you turn on the A/C it bypasses the heater and if you have it on the hottest setting, for the A/C that’s the least cool setting, right?

I didn’t think they both worth at the same time. Thanks for anyone with knowledge out there.

And what do you do if your heater doesn’t work? I always Crack open my window and wipe my windshield from the inside

The best method I found was to lay a wet/damp towel over the outside of windowscreen the night before. Then simply remove the towel and drive onwards

Only problem is most a/c’s wont work below 5C (~40F) because the moisture it extracts from the air can freeze up and destroy the evaporator.
