Chargèro : Now make a video on how to deFROST :)

Porglit : Use shaving cream to shave off a couple minutes from your morning commute. Cute.

Alexandre SAINT GEORGE : There seems to be some confusion here between "de-frosting" and "de-fogging" / "de-misting"...

Darin Hawrylak : In Canada you can't always open your windows cause 90% of the time the windows are frozen shut

Simply Me! : My mom just turns on the wind shield wipers

TheBackyardScientist : I discovered an even easier to defog your windows.. Move to Florida!

iaag o : you could just wipe it with a towel

Moose Musson : I know the quickest solution, use the garage!

MiningwithPudding : 5:10 The add before this video was actually about "chem-trails".

mistaxtony : Ahh no wonder the a/c gets turned on when I switch on the defogger/deicer

TurboCMinusMinus : Does this also work with linux?

Hezekiah Domowski : I didn't know that any car will do heat and a.c. - mine doesn't

Jonny DIY : *Close shave, America. Close shave Barbasol*

6977warrior1 : Turning on your AC when it's super cold outside will ruin your AC compressor. Do not do what he says.

ANIME GODZ : Umm...just use a bucket of warm water and pour it on your window and it defrost in idk 0:5 second

GunnedDownAtrocity : Mark seems like a really nice a guy. Like a guy you could hang out with at a picnic all day. And a few hours in, you'd be absolutely annihilated, while Mark has paced himself and may or may not have a slight "buzz." But he wouldn't judge you for it. And he would at least appear to still have a good time. Because he's a really nice guy.

Lance Roark : Does his looking off screen to his friends bug anyone else?

David Albee : Can you explain the shaving cream hack more?

Veedo C : I stopped watching after he said "suckiest"

Ry P : Thank you for identifying the mysterious blue liquid they use in ads for menstrual pads.

Skykid : Turn your windshield wiper on boom gone

gothops154 : I'd recommend not using AC when having the blowers directed on your windows as over time it can leave an film which makes it foggy and hard to see out of especially at night.

J Girl : I just did a test of the shaving cream on my bathroom mirror. If it works, my car is next! I'll know in the morning


Chrnan6710 : The Rober Principle: If Mark makes a video, it goes viral.

Webster Youngblood : Chemical trails and condensation trails are not the same

Chris R : Chem trails are real

Chargèro : Fog and humidity is nothing, try coming up to Canada where we have freezing times. Also when snow hits the warm glass of the car you have just been driving, or when it's warmer during the day and the temp drops at night, this causes frost build up on the outside of the windshield (usually at the bottom near the wipers, usually freezing them in place). Harder to remove and takes longer. If you have cracks or chips on your windshield, an excellent way to turn them in to a spiderweb is to beat at it with a scraper or blast the defrost heat directly on to the windshield. Also cranking the wipers when they are frozen in place or covered with heavy wet snow is a perfect way to break them or burn the motor assembly. Frost builds up on the INSIDE of the car when you have water/melted snow in the foot wells, or the floor mats are damp. When you lave the car parked, and the temp. drops at night, the rising moisture freezes to the inside of the window. The best remedy for preventing it is to keep the inside of the car dry as much as possible, like putting news papers in the foot wells, and silica packets on your dash to absorb any rising moisture that may reach the windshield area. Hopefully you learned more from the info in my comment above than having wasted your time watching this video.
