Defog your windows TWICE as fast using SCIENCE- 4 easy steps

open all four doors for a minute

This assumes that it won't get colder in the night.

@@chrismartin1318 the goal is to cause less condensation to build up… not necessarily to cause it to be non existent. Most places that deal with the condensation are a situation where they are driving around with the heater on, and it is much colder outside. He’s just saying to leave the doors open a bit so it’s not so hot in the car compared to outside.

@@EmronWalker I realize that. But as an HVAC tech who does this for a living, I can say that often times if the car is parked when the sun is out then driven again early the next morning there is a usually at least a 10-20 degree difference. This difference is usually significantly greater than any change in just opening the doors and equalizing the humidity with the outside. Another factor to consider is that if it's raining you'll actually be putting more humidity into the vehicle due to the humidity outside being near or at 99%. Humidity changes outside quite often during the night and not necessarily in a direction that would be beneficial to this method.

But the ice forms on the outside of the vehicle, the conditions outside don't know what's going on inside

So this phenomenon is the same thing as Rain-X has on the outside of the window?

I like you.

@@mggt4684 depends on the brand, but it's probably at least cheaper.

Does this mean that the condensed water will probably run off, potentially down the back of my dashboard? Or just not stick to the window in the first place? I don't want to simply "move" the problem 🤔

@@edguix, we had a very wet winter, and when frost came, I hadn't been able to open any window in my car. Now it's the storm season, so the wind is too strong. In other words, this technique works like a charm when the frost is moderate or when it's raining outside.

@@edguix For me, in freezing land of canada, the best setting depend on how hot the engine is. The engine is too small and do not produce enough heat at idle.
If I just started the engine, the best is: hvac off, wait a few minutes, hvac to 3/4 and windshield only. The car force the A/C to be on and recycle forced off.
If the engine is already hot, full blast and windshield only.
I hasn't found that opening the window made a significant difference EXCEPT if you warmed the inside (hot air at the feet) as it increase the humidity way too much (due to melted ice = water, hot water = humidity). After all, you are pulling mostly outside air.
in other words, hotter air is better than more air.

@@thephantom1492
Spoken like someone who actually knows what ice encrusted windows look like in the hinterlands of Canada. I do exactly the same thing. 👌

You can thank my dad for the adhesive bonding chemical in cat litter, he invented it back in the 80s

but like why can't u do that lol

@@AdamHallacher because fog builds up between the panels of glass as well. The defroster allows the ice to melt on the outside of the windshield, gets rid of fog on the inside of the vehicle but there is moisutre build up that you cannot just wipe with your hands or a towel that needs the defroster only to go away. I mean try it with a towel not much will change because you are not actually wiping away most of anything. The inside of the cab can be completely clean but still have fog everywhere else.

Some cars have electric heaters that work as soon as the engine runs. And they also ruin the battery, which is coincidentally sold by the same people selling cars.

Wait, how are you driving for 2-3 minutes with fog on your windshield?

How do you drive for a few minutes out of a window you can’t see out of?

So you start driving with your windows still fogged?? What time do you leave for work so i can keep my kids indoors !

Dose that really work my windows have ice on windsheild

@@pamelasuemoreland3315 in my experience no cuz I've literally tried this many times before and the cold air from the outside chills the hot air from the defroster

Yeah I do that in my house to I take all the 32 Degree air from outside and heat it up to 72 degrees😎

And then wonder why lower part of the windshield is full of cracks

For lazy people: drive with the fog

Stick your head out the window xd

instructions unclear, my window is now shattered

I have an 02' Blazer & defroster blows hard & hot but the windshield stays fogged up. My Controls only have A/C, or Heat. Unable to turn A/C on with Defroster on. It's one or the other. This problem just started. Defroster blows hard & hot but it does nothing to this windshield. I'm curious as to why. Normally hot air clears the windshield quickly.

@@JB-yb4wn I'm in SK. Obviously this is only for when you will be away from your vehicle for a somewhat extended period of time.

+Andy Cox I was thinking the exact same thing. Ice forms on the OUTSIDE of the window.

His techniques for defogging are correct I think he just used the wrong wording in the thumbnail. BUT yes ice forms outside of the window. In that case you can still just scrape it off or wait for the air to warm up and let the ice melt.

Precisely what I came to say, as well.

+Andy Cox Recirculating would give you warm air quicker but you are likely to get better defrosting at the expense of more fog inside the car.

+Hugh Gilmartin That's not necessarily true. If you're in your car and breathing inside it so the air is warm and humid, then get out and leave it overnight when it's very cold, you'll get ice on the inside as well. My car had ice on the inside yesterday morning. It was -22C overnight, and I'd been breathing inside the car the day before, when it was only -10C. My breath condensed on the window after I'd gotten out, then froze.

leaves marks (small bits of the water still not fully into water droplets being spread all over it.)

Ya I'll just put on my large towel helmet and climb in my large towel cannon and blast off to large towel land where they have all the large towels!

@@emac3628 right? Like where the f am I supposed to get a large dry towel?

Water builds up in between the panels of glass

Well, usually the latter on the inside go hand in hand with the former on the outside... so it kinda gets lumped together.
When you have to defrost the inside of the car (which I've had to do maybe twice before) you know things have got truly serious. All the same, this method will still help you to do THAT faster as well (warm, dry air will assist the ice in both melting into water and subliming into vapour)

mspenrice where I live pretty well every time I get into my car in the winter there is frost on the inside of the windshield. It’s really common anywhere even remotely northern.

Define "remotely northern". I live somewhere that's considered by some to be at least technically in the north of the country, but it's "only" about 53 degrees above the equator. Which is enough for decently wide swings between summer and winter (like 50'C / 90'F between the highest heat and the deepest cold)... I've only seen frost on the inside of the car when the temperature has dropped somewhat from near freezing to double digit negative celcius, ie so there was still SOME moisture in the air, which then ran into an extremely cold piece of glass that froze it in place instead of spreading it out into a still-technically-liquid misty covering...

mspenrice it depends on how many people you have in ur car, since more people brings more snow in, which melts and then condenses on the windows and freezes. As far as remotely north I should have said anywhere where in winter it’s below freezing consistently. Doesn’t really matter

We regularly have winters where it can be subzero for weeks on end... still only seen it happen 2 or 3 times. Also, the frost I'm talking about is already on the inside of the screen when you get into the car... and wouldn't more people cause the interior to warm up faster?
I guess what I'm asking is where *you* are. No need to be exact, like, just general area of whatever country or state...

+Koppa Dasao I see what you did there

Betzabé Nazario Yeah, it's nasty.

***** Oh, I see what you are talking about. Yes, there have been attempts at mixing asphalt in different ways to reduce the amount of heat stored in the roads in an attempt to reduce the environmental impacts of roads. So far the best solution was invented by the romans more than 2 millennia ago…, the substance called concrete…

yep, exactly like me, for me the recirculated works much more faster then the fresh air

@@JS-jt4fn tip: save a cup of hot/warm water from your breakfast coffee/tea and if your windscreen is frosted put said water in a clear bag (or ziplock bag) and pass it a few times on the windscreen.

+BuNNieSklZ He told you how to get rid of water the fastest in the already liquid state, not the solid state. It would be a different method for frost/ice.

+Twiztidguy Plus, frost is on the outside of the windshield, which is a much bigger factor than the state of the water. And humidity doesn't enter the equation. All you can do with the air system after the fact is throw heat at it. Any tips for prevention or removal would be radically different.

+drakono82 Yeah, no. Frost happens both inside and outside of the car, depending on what state you left the car in. If it was warm and humid inside the car when you get out, and it was really cold out, you'll have frost on the inside of your windshield. It was like that in my car yesterday morning.

+Huangism rain-x makes a de-icing windshield fluid. it works quite well and adds the water beading effect. as for fog inside, just open your windows for a bit before you arrive at your destination. it should equal out the moisture that's been collected. i think anyways.

use an old blanket to cover your windshield over night...in the morning all you have to do is remove the blanket and you are ready to go, simple as that

I think someone did a video and said using a ziploc bag with hot water and rubbing it on the ice helps

Ditto

+Mark Rober I see what you did there! Also, while you're here, on a water bottle rocket, are long fins, or short fins better, do you want it to spiral, and what is the best ratio? I would like to see a video on it, or, if you don't want to do one on that, then you could just reply, which I would be just as happy about! Thank you!

+Mark Rober :D a reply from mark

***** Thanks for answering! I have (basically) already done so, as I did it in my honors science class recently. Our rocket, which had three long straight fins, a screw on cone (as we had to put a payload in/on it), and was filled with 1/3 water, 2/3 air, and went the highest, compared to about 6 others which were each altered differently. I just wanted to see what you would say, as you worked for NASA. (Also, I gave my science teacher our rocket, and made a replica afterwards so I could work on it at home). Thanks again!

+Mark Rober Why do you keep saying "believer of the scientific method"?, this is only bait to any "non-believer" (using your terms) to argue that science is a set of beliefs. It isn't. We use the scientific method because, so far, it works. If some better method comes along, well then, we change it.

Scientific method = hypothesis, prediction and experiment. Strictly speaking experiment and observation without model, hypothesis and prediction isn't scientific because it isn't an effort to extend understanding, It IS, however, the basis of engineering, which is applying knowkedge of phenomena to produce desured results.

Of course you cant see anything through them, they are probably shattered to pieces now.

+Jim Bryson Electrically heated windshield. Extremely useful. Or just use something to cover the windows up, that helps too.

I know that, I live in South East Queensland and yeah it does get pretty cold but from where I am living it does not often fog up window screens

Me who lives in Alaska.. takes note

@@connorvickers2053 As another SEQ'er, I have experienced only 2 winters in my life that involved actual ice on windscreens.. A garage or even parking on concrete with a roof/shadecloth overhead is usually all it takes to prevent iced/fogged screens all winter
First icing was at highschool in the early 2000's, in Noosa, my sister had a VL Commodore which she drove us both to school in. Somehow that winter got weird and the VL (parked on grass) got like a half cm thick ice over the windscreen.
Her immediate thought was to grab the hose because what Australian even owns an ice scraper?.. well the hose snapped in 3 places immediately because it too was full of water and sitting on the grass.
Step 2 was going to be boiling water from the jug which I -VERY- strongly advised against, instead getting some cold tap water to drizzle over it and it melted within a few seconds.
Second one was in Warwick, which is far enough inland and has late sunrise due to mountains, so understandably cold winter mornings.. 2010, I rode a motorbike into class, wiping my visor with a glove a few times at the start and cracking it open when stationary was all it took to see ahead. Meanwhile one of the other students poured hot water onto the icy windscreen of his mid 90's Celica... turned up to class with a giant crack in the glass.
And a group of students who carpool together turned up going less than half the speed limit, all of them hanging their heads out the windows shouting to each other about direction and obstacles like morons because they never bothered to de-ice it. Highlight of my day for sure.
But anyways, since this vid is more about fog than ice - I've never really had that issue unless I parked on wet grass as above, and the worst case of internal fog was fixed with a quick wipe with a microfibre cloth.. which unlike using your sleeve is actually clean and doesn't leave streaks. One wipe before driving off is all it ever took.

I remember the first time I heard the term windscreen (I’m from Texas) I was so baffled, like, “England had SCREENS on their car windshields?!? That’s AWESOME!” To be honest, I’m still pretty disappointed that it’s just a glass window. And what’s up with BOOT? Again being from TEXAS...🤠

Which one?

Got a 2013. Can't wait to make use of this new knowledge 😭

You mean a squish

Yep, this is why newer cars automatically turn on the AC when defrost is selected. Most people already know this. I don't like blasting hot air during the winter time though as it can actually break the windshield. So I blast it at medium settings when it's extremely cold.

Blasting the windshield with hot hair will break the windshield this guy says lmao. ^

What if you would rather circulate the air as opposed to defrosting faster?

My Mazda also turns off recirculation with defog automatically!

If it's a new car (last 15 years or so) it will do this automatically. Humidity in the car is often higher than outside air, so manufacturers disable recirculation during defrost to prevent people from leaving it in this mode and complaining that it takes too long to defrost.
