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

So you turn on your A/C, which is going to cool the air, but you turn up the heater, too.

Eeew sorry dude, i don’t think the A/C is active when you turn on your heater at the same time.
Why should a car cool down air and then heat it up again, i guess it just shuts down whatever you switch on first.

This guys an Engineer, i guess he knows what he is saying but i don’t get it.

Could anybody her explain that to me please?

I cracked all the windows and now I don’t have windows. Thank you.

Science BIITCH!

OK so you can use shaving cream as an anti fog for your windshield, but can you use anti fog as shaving cream?

Thanks man I have this problem all the time!

“Most of the cars controls look like these” - Mine is not in this group :D No front defrost… No cold air… What I’m supposed to do :D

Funny how many people don’t know the difference between “Frost” and “Fog” and use them interchangeably.

that’s all i can say:)

The real question is, on a cold morning, how long do you wait (if at all) for the engine to warm up before turning the heater on? Its been suggested that turning on the heater immediately after starting the engine makes it take longer to warm up, thus taking longer to defrost/demist.

Simple answer: Put cat litter in a sock and tie the end, it reduces humidity better than a few of the tips here.
