How to Stop Car Windows from Steaming Up

Hey guys Chris fix here and today I’m going to show you how to prevent your windows from fogging up. Sure you could use products from the store to keep your windows from fogging up but did you know you could find products around your house that will do the same thing In this video were going to test potatoes, baby shampoo, hand sanitiser and shaving cream against the store bought anti-fogging treatment so lets first go over why windows get all foggy. Fog happens because theres a temperature change and because theres humidity… right now its cold outside, my body heat is warm, and my breath is warm and its humid… and thats what creates fog in the winter time. In the summer time it’s kind of the opposite, it’s warm outside… but you turn your AC on on the inside, so it’s cool on the inside and any of the moisture inside the car… is going to turn into fog on your windshield. To get the glass foggy I have a hot pot of water… as you can see the glass fogs up completely… and this is our control test, so that you know the glass will fog up. Now I can go and clean off the glass… and we will section off the window in 5 parts to test each defogger. Now with the window sectioned into 5 parts… let’s apply the products. The first product we’re going to try is the Rain.X Anti Fog… the directions say just to put some on a towel… and just rub it right on the glass. Make sure you cover all of the glass… and then take a dry spot on the paper towel and lightly wipe so it removes any streaking. So the top left square is the Rain.X. The next product we’re going to use is shaving cream. All you do with the shaving cream is get a little bit onto the glass… and then you work it in with a paper towel. I’m using a new paper towel so we don’t contaminate. Again make sure you cover all the glass. Now you buff off all of this until it’s clear. And eventually it get’s clean, this definately takes a little more effort then using the Rain.X… Ok our shaving cream on the top here is done. We’ll move down to the bottom corner. On the bottom corner I’ll be using an old scuba driving trick that I use for my mask. If it keeps the mask from fogging up 60ft under water It should work on my truck so we’ll just apply that, again making sure we get it everywhere and then we’ll get a clean paper towel and just lightly go over the top So we remove any streaking so its nice and clear When your doing this you don’t want to remove the layer you’re putting on here you just want to make sure you can see through the glass and its clear Now lets test the potato So your probably thinking potato ? what the heck ? this is one of the urban legends as a scuba diver, you’re suppose to be able to split a potato And then just take the end here And you rub it on the glass Make sure that you cover all of the glass The Liquid from the potato is actually pretty clear, Maybe this will actually work To be honest with you i’ve never actually tried it Get a clean paper towel and we’ll just lightly buff off any off the streaks And thats streak free and looks good And then the last one is going to be the hand sanitiser just get a little bit and put it right on there and then we’ll rub it right in And then we’ll get a new paper towel and buff it out Get that nice and clear just like the others So in this corner we have the rain.x Shaving cream Baby Soap Potato Hand Sanitiser Now lets go get the steaming hot water and see how it works So we have our hot pot of water Lets test it out So as we can see our rain.x And our shaving cream Worked great Now if we go down to the bottom here Our baby shampoo left some kind on residue when it gets humid so it does not look that great Actually feels kinda soapy, which makes sense Our potato again, left some kind of residue, doesn’t look that clear, its not soapy at least And then our hand senatiser which is alcohol the reason people say it works is because its alcohol That obviously didn’t work So from our results we can see the top 2 came out great These 3 didn’t work out that well The Worst being the hand sanitiser But the Potato and the baby soap didn’t work that great either So in conclusion the shaving cream worked just as well as the store bought rain.x Everybody has shaving cream at home So in my mind its a clear winner, you don’t need to go out and buy anything special It didn’t fog up, it looks nice and clear, and it was pretty easy to apply The results speak for them selves Before and after No shaving cream Shaving cream Pretty good difference there Hopefully this video was helpful If it was, remember to give it a thumbs up If you’re not a subscriber, Consider subscribing

  1. Okay. … now I've got a question for you.
    After a night and when I want to drive of with my Cabriolet in the morning, I have condensed inside windows.. so how can you prefend that from happening?

  2. I've got one for you to try, 👍 cat litter put a few handfuls in a sock or use both socks, and bingo the cat litter holds the moisture,
    Ps don't rub that cat litter on the Windows just leave them in the car, 👍

  3. I tried shaveing cream once.
    No fog, but couldn't see anything at night due to smudges and dirt sticking to it

  4. Chris fix you're an all round man i want to do some mig welding. I want to ask you a question how fo i keep my engine looking nice on the hoses

  5. Just get Rain x Anti fog. In walmart it's $5 and last longer. Use shaving cream/gel as a last resort type of situation, like if you were out in a ski cabin and didn't have a walmart near by.

  6. He probably just forgot that we are waiting for the results 😂😂😂I guess we will never know…cuz I'm too lazy to try it..so I want results before I do something here people 😂😂😂

  7. Shaving Gel last a few days. I use it in the bathroom mirror when you shower with hot water.

  8. We dont have time for this shit, just open up the window , let the cool air comes inside the car, fog will automatically go!

  9. Shaving foam is not effective & removing it from window is very very hard..Removing it from 3 days now

  10. Mom: Why did you keep a shaving cream in the car?
    Me: Because I can shave on the drive, when I am late to the office.

  11. Ok let's talk shaving cream, did you use menthol, regular, sensitive shin, gel, instant foam, come on man I need details. I'm dying over here

  12. Another video was with toothpaste but it was totally failed. And now you are trying with s shaving cream & showing its successful. I will try with shaving cream, if its failed that will prove you are a lair.

  13. Tell me how to steam them up instead.
    I really need to know that. Hotel rooms are getting expensive day by day. 🙁

  14. try 100% rubbing alcohol hand sanitizer has other shit in it maybe that is why it didnt work

  15. Just curious, what is the exact ingredient in the shaving cream that makes this work? Maybe there are other products that contain it that we could use. Also, does it matter if we use shaving cream vs shaving gel?

  16. Why not just buy a modern car that automatically turns on the A/C with defroster settings?

  17. Ive been using shaving gel for the small mirror in my shower for when I shave my head…never thought of using it in the car – thanks!!

  18. VERY GOOOOD but I have my own tested tip:
    Use the car's air condition, heat or cool, to do the work for you, anytime you want.
    Point the air blowing to the glass you want and keep it open.

  19. Seriously helpful! Driving around in a thunderstorm gets it foggy and cant even see the side mirror.

  20. The baby shampoo is what I’ve been using and it’s pretty good for me, and it smells nice

  21. Or just don't let anyone roll the windows down in the rain. Solves 90% of the problem. Then also keep "A/C" button on (if it exists) without recirculate to dehumidify.

  22. I would just suggest you guys use glass cleaner to clean your windshield and that would be enough

  23. The window fogs up due to the film of scrum on the glass surface that absorbs moisture …a clean window won't fog up as much it might condense on the window

  24. Hi Chris: Do have a remedy for fogging on the outside of windows during the Summer? You know, cold windows on a hot muggy day = outside fogging. How does one stop that? Thanks in advance! – JM

  25. Just turn recycle air off and turn on the AC with the heat. My windows never fog and live in the north east.

  26. At least now I can use my shaving cream in two different ways 😂 that saves money 😝😝

  27. Back in the day, I learned on Reading Rainbow that scuba divers use spit on their mask.

  28. My grandma used pinesol she applied to the bathroom mirror never fogged. She applied let dry for a day then wipe clean.

  29. Just spit in your scuba eye wear rub it in then dunk it in the water to rinse. Shrug. Never had a problem even in ice water. Shaving cream, will have to try on windshield, cool video.

    I add that rainex booster bottle to fluid, definitely see better.

  30. 28 and asian. Still waiting for a day I can officially buy shaving cream… 😥
