How to Prevent your Windows from Fogging Up

It was at this moment the window knew he fogged up

9/10 dentists of course approve this.

@ChrisFix my husband and I are truck drivers. We were having trouble seeing our our windshield in the rain and used the toothpaste. Works like a charm. You are a lifesaver. From my husband and I a million thank yous my friend!

This is good to know when im driving around with my boiling pots in the passenger seat.

i find removing the windows works perfect, bit cold though when driving. lol

Wooder doplets they will grow up and be some nice soapy wooders

Imagine being that man walking his dog and seeing a man spreading avocado on his car window

Chris seems like the dope ass friend you'd want he's so chill and laid back but very very informative gotta love him!

A tip that might be interesting for you to know, Chris, is that we, up here in the arctic north, learn to vent out the heat from the car, once you are almost home.
Hot air can hold lots of humidity, which will condense once it cools off, where cold air can contain almost no humidity at all.
So, when you are driving home, for example, when you are 30-60 seconds from home, you can open your windows a little, and turn off the heater in the car. Next morning, very little, if any, fog on the windows.

i must admit... i cried when the onion didn't work ;)

The fact this dude is still replying to comments shows his dedication to KRplus.

Toothpaste & shave cream, thanks :)

Not only are your videos informative and interesting, but you also take special care in answering potential questions that most people segue into. Well presented, painstakingly detailed and absolutely entertaining. You sir, are a gentleman and a scholar!
Big fan!

Does it work on windows xp ?

The clarity of your demonstrations, and explanations is second to none.

Everybody’s got toothpaste
Crackheads: aM i A jOkE tO yOu

I liked how you did this as a scientific test procedure with control and common application. Nice work! I liked and subscribed! Will check out your stuff. Thank you for taking the time to do this testing so we don't have to!!!

Try black spray paint.

I love your presentation, explanation, and execution. Thank you for the insight and tips! Kudos to you! 👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽

Terrific video CFix, great demo and actual, clear-to-see (no pun intended) results. Nice job indeed young man. Many thanks!

*(now you know why "high quality" precision optics are coated with Fluoride)* How does a cloud form? Dust attracts water (surface tension). Fluoride *_seals_* the pores of the glass, and makes it slippery- so dust can't be attracted or embedded into the surface. A high SPF suntan lotion or a "chapstick" type protector will also work. A high quality clay bar, followed by a silicone wax works awesome for glass _inside and out_ too!

Chris, great videos. I've seen several and I appreciate all the effort.I'd like to add a little bit here though:* A decrease in temperature actually increases Relative Humidity. The best way to clean your windshield is to turn on the AC if you have it, but increase the temperature the temperature. That way you are using both the drying effect of the AC as well as the drop in RH due to the temperature difference across the heater core.This will also help by keeping water from condensing outside on the windshield caused by using cold air from the AC.

Great video, we came up with the same answer as bicyclists. It’s a great idea and we have been using it for years as an anti-fogger. Thank you very much for sharing.

I know this is an old vlog but fantastic video Chris mate I’m just going through your older videos I’ve been a subscriber for a few years now love your channel keep up the great work

I love when you go all Marine Biologist on this stuff! SCIENCE! The next test should be defogger, toothpaste, shaving cream, and control. Also (I know you know), but the defogger goes inside the mask to be effective. Awesome video!

Where do I buy the spit from?

I just love how much effort you put it in your videos. mad respect.

Hi Chris ! Thank You! Wishing you the best health 💜💕

Why is that poor man rubbing avocado on his car windows

Something that works for me better than the defrost option in the AC, is to turn AC on, and maybe turning on the heat so it won't get too cold inside. It sort of removes the moisture, and does it faster than the standard defroster. Specially when your AC system lets you redirect the AC to any of the vents.

Amazing! It works. I am super grateful for this tip. You may not realize just how much this helped me today in the situation I found myself. All I can say is thanks a million.

lol, just started watching you because i'm a home owner now and man you killed it with every video with no BS just right to the point. You da man. You got a new subscriber lol.

Chris it's 600 in the morning I was asleep and my headphones went up in noise saw it was you uploading interrupted my sleep to watch your vid love them you've helped my truck look sooo much better I appreciate it more than you'll ever know thank you so much!!!

You had me at "control area"
Subscribed!

my AC compressor went out in my favorite truck. so I literally had NO defroster. this helped my stress level in the morning trying to drive to work ... Rain X did the job, Love you Man !

Just came from your old video where you didn't use a control. You may not notice it but your videos are always improving. I really enjoy your channel - thanks for your time.

0:34...Chris Fix cameo in the lens of the glasses :)

I personally just throw those silica gel packets near my windshield (normally on the defroster vents). I have a ton of them from Amazon packages, and they work awesome. I only use two for the whole front windshield, and they work perfectly. The only disadvantage is you can't put them on the side windows.

Early today I just found out my defrost doesn’t work in my car. Until I can afford to fix it I’m going to have to do some sort of home remedies for the inside fogging up. And I would just like to say THANK YOU, THANK YOU, THANK YOU for making this video I watched both parts to this experiment you did here. And I just cannot thank you enough because I am so appreciative that you Actaully showed the before, during, and after. Every step of the way. Comparing multiple products. And I just found this extremely helpful. Like enough to the point where I’m commenting (because I don’t really do this) so I appreciate you and the work you do here

Windex works great too! It’s best on the outside if you saturate the window but you can spray it on and wipe it off too. The ammonia is the key ingredient to keep fog away. Though it’s a temporary fix it works great on humid nights in the south so you don’t have to turn the defrost on in the summertime.

I have the Rainx Anti Fog and I must say it didnt work well for me when I used it on my windshield. It actually kept a light film on my windshield that made it harder to see through combined with the fog. I am going to attempt using some shaving cream or the toothpaste... Thanks for the tips !!

Thanks heaps @ChrisFix 🙏🏼
After watching your video, I had tried the toothpaste.
Can confirm that this actually works.
Have done it for my front windscreen, side mirrors and side windows.
No fog has built up since then.
Thanks heaps again @ChrisFix 😁

Thanks for the video!
Saturday morning here in Belgium, 7am. Just found out my heaters and demisters in the car stopped working. No shops open to buy products and i need to hit the road now for a 105 km trip. A quick look in youtube found your tutorial and Just enough time to apply the toothpast.. (though not colgate).
I will post my experience when I arrive at my destination.
If you all never here from me again, well... 6 feet under is what happened.
I really appreciate the efforts in the video.

Thank you for making this video! All of yer videos have helped me out with my car tremendously!!!!

5:32 "The untreated control is all f*cked up"

Chris , you gonna make toothpastes prices go high .

Sup chris your tutorial was a big help for everyone of us. I hope you make a lot of this..
Respect from the Philippines🇵🇭🇵🇭🇵🇭👌🏻

Thanks for your very detail experiment and effort to show the best result.
Cheer, have many great days
Hien Le

Chris your videos are the best and the most useful thank you for everything

"your windscreen is really clean"
> Thanks, I spat on it

thanks Chriss, i really appreciate your work for i live in a town where no such thing as anti fog is available, your videos are great and practical,and i suggest that you use more common tools and products for your next videos cause where i live i dont get much choices for any thing , thanks for the great gift, for knowledge is the best gift to give away :)

Chris your video is fantastic. I like the way you demonstrated. I will try toothpaste. Shaving foam did work for me

Thank you so much :D. Works perfect in my truck!. Greetings from Venezuela.

Brighter and Fresher Windows in 2 weeks LOL!! Thank you for anther awesome video ChrisFix.

Dang! I just found this channel! How have I lived without this channel?! I won’t take a chance of living without it now!

Love your channel. No bullshitting. Short and effective.

You're the MVP of KRplus.

Small correction about dive masks. Toothpaste is used to remove the layer of silicone on the inside of the mask. After that, you want to use baby shampoo as your actual defogger, not toothpaste.

Chris! Thank you for your videos. I really enjoy them.
I have a request: can you show us the right way to install an Android Auto capable device into a old and new Toyota Camry? I feel that you would give the best coverage compared to other KRplusrs.
Thanks!!

Thanks for taking the time in making this video. One other point regarding the use of Rain-X. Some might think they can use it on their googles or glasses. The problem is this could pose an issue. Its obvious that Rain-X has chemicals in their product, which could result in a reaction to one's eyes. Personally, I would not want to put something that has chemicals too close to my eyes, even if you think you have wiped the balk of the product off your eye-ware. Sweat might release and/or reactivate some of these chemical thus posing a possible reaction. One should always use caution when using anything that could come in contact with your eyes. Remember… toothpaste was created for brushing your teeth.

I would love to see this same kind of side by side test for rain on the outside of the windshield with rain-x vs. the car wax you used in your super clean windshield video

How often should be de-fogger applied ? Thank you so much

Hey Chris great test!!! Thanks

Thanks for this tip!!! Great job

Hey @ChrisFix - your videos are great man, thanks for making them. How long do these last before you have to re-apply them?Between this video and your other one on anti-fogging which product is overall the best? Rain-X, shaving cream, toothpaste? Does the Rain-X last longer?

that microscopic camera is cool, might help me find the reason why my dad left

I really enjoyed this video ! Great job done 👍👍

Great channel and such useful advice and tests....thank you

Great vid, never expected toohtpaste won !

"Everyone has toothpaste." **Considering some of the people I work with, I don't really know if that's true. ;)

I have watch alots of ur videos, I just subscribe today. bless up, -im from Jamaica

Amazing vid. Love your comparisons

Good vid you lil mythbuster you !

You wouldn't want to rub onions in your scuba lenses anyways.😂😂

Awesome vid.. can’t beat examples and comparison side by side 👍🏾

Appreciate it Chris thank you very much Chris any thoughts on using toothpaste on both sides of the windshield?

My fog is on the outside of my windshield from my A/C because it blows a little bit out the defrost. But I also live in the south we’re it’s really humid

I love your commentary... "This onion was made for the window"😄

That's just brilliant. What do we have steamy bathroom mirrors when the products to prevent this is in the bathroom.. thank you Chris.

Both fog prevent videos are killer thanks for the analysis

Use the little silica gel packer out of beef jerky. They are meant to absorb moisture and work well. 2 for the windshield and back window. 1 for each side window. It helps to put them in the inner window seal. Works fine if you have tint as well. Hope you'd make a video on it. Hope it works

car polish paste wax seems best do inside and outside makes frost outside easyer to remove too house furniture polish works too and the old stand by shaving cream

Where did you get that camera @chrisfix (the microscope camera) I do macro photography and that thing is sickk! Great informative content as always.

Great video!!! Do u apply only from the inside?

Very nice video. It's lot of hard work to create good video

Chris, great videos on anti fog. Have you tried WD40? I've heard it works. Keep the great info videos coming. Thanks for your time & effort.

I used those little bead packets you get in shoe boxes and different products one time. Worked great. I lined them up on my dashboard and they absorbed the moisture and kept my windows from fogging up. But of course they got annoying after a while, so I ended up removing them.

Your videos are fantastic. You make KRplus better. Thank for your help.

i would like to know how long these remedies last in comparison with the pro de-fogger.

You should try to compare the normal anti-fog for car windows with the expensive anti-fog stuff they sell for optics (cameras and rifle scopes etc).
Make sure to test for durability as well. We don't want to lose our anti-fog every time we roll down our windows.

Chris you should do another video where you take all the good ones that work and see how long they work 4

Well done, Chris.

Coulda swore I already watched this like a few months ago.....

I will also use it on my glasses so I will be able to boil pasta without being blind

Awesome !!! I'll try the tooth paste, it was so hectic to drive when it rains, I really use to curse that when I was driving just because of foggy windshield

Wow what tools U have. Great vid as always 10x

hey chris, off topic request! - can you try the Acetone in gas for better fuel mileage? guess you can make it into 2 videos to see if it's good at decarbonizing in the engine. thanks man i really hope you do this test because I know you do it right and honest!! thanks!

Ok Chris, so here we go again. As you proved, toothpaste works great to prevent fog but here's my question, (and I hope you don't find it crazy, but does one type of toothpaste work better than another (ex: paste, gel, combination of paste & gel, flouride-free [which I use])? I'm sure the brand doesn't matter, as I will head on down to the dollar store once again, but what about the type? Do you think a test is in order? Have you figured out the active ingredient that makes it do what it does?

You’re the best that worked thanks!

Hi Chris
Good vid mate thsnkyou
If you havent done one already can you do one on keeping your windscreens ice free
Bet youd have some good ideas
