Remember kids, when making graffiti, always cite your sources.

On the bathroom stall:

Here I sit all broken hearted,

Came to shit and only farted.

Then one day, just by chance,

Tried to fart and shat my pants.

Good time to share How to use one paper towel (to thoroughly dry your hands in a public restroom).

Shake. Fold. It really does work.

[–] UnRelatedBurner@sh.itjust.works 15 points 2 weeks ago (1 children)

that was a nice watch, but more times than not I just use my pants

[–] Empricorn@feddit.nl 43 points 2 weeks ago

I try to use your pants too, but you walk really fast.

Funnily, that's not really true. Such studies showing that exist but are sponsored by… paper towel companies

[–] Karjalan@lemmy.world 37 points 2 weeks ago (1 children)

Fucking dystopian late stage capitalism... Every fact is not actually a fact cause it's sponsored by corporate interests

[–] infinite_ass@leminal.space 12 points 2 weeks ago (1 children)

Half the words are automatically capitalized when I text. Because they're part of a corporation's name.

Yes, and the ones that show air dryers to be healthier are funded by... hand dryer manufacturers.

[–] RQG@lemmy.world 13 points 2 weeks ago (4 children)

Someone should fund independent research.

[–] ZeffSyde@lemmy.world 26 points 2 weeks ago

I went for a whole month drying my hands with only independent research and the results were similar to using paper towels.

I particularly hate those airblade things even more than regular air dryers. I like that they're faster and typically not as gross and warm but they are designed in a way where you feed your hand in to a narrow gap with powerful air jets in front of and behind your hands in this gap. Your hands are not a completely uniform symmetrical shape, so the jets buffet your hand around and they inevitably touch the parts of the device where the jets are located, right where everyone else has had the same thing happen. It grosses me out.

[–] srestegosaurio@lemmy.dbzer0.com 15 points 2 weeks ago

And also incredibly loud too.

Is this true? Seriously curious.

[–] daddy32@lemmy.world 47 points 2 weeks ago* (last edited 2 weeks ago) (2 children)

This is not hot air though, so the cited source does not apply.

Edit: but it does link to more relevant study towards the end, comparing different means of hand drying.

[–] Mannivu@feddit.it 34 points 2 weeks ago (1 children)

You're right and I linked a fairly old study. I've edited my comment to add a more recent source.

[–] daddy32@lemmy.world 21 points 2 weeks ago
[–] kautau@lemmy.world 19 points 2 weeks ago (1 children)

Findings: Air bacterial counts in close proximity to hand drying were 4.5-fold higher for the jet air dryer (70.7 cfu) compared with the warm air dryer (15.7 cfu) (P=0.001), and 27-fold higher compared with use of paper towels (2.6 cfu) (P<0.001).* Airborne counts were also significantly different during use of towel drying versus warm air dryer (P=0.001). A similar pattern was seen for bacterial counts at 1m away. Visualization experiments demonstrated that the jet air dryer caused the most droplet dispersal.

Why are there germs on your hands right after washing them? Didn't mythbusters already test it and concluded that they are only bad when people don't really wash their hands.

[–] Bassman1805@lemmy.world 40 points 2 weeks ago

Yes.

The followup question is "how many people think getting their hands wet without soap is sufficient hand-washing" and the answer is not terribly comforting.

[–] MonkderVierte@lemmy.ml 11 points 2 weeks ago

that they are only bad when people don't really wash their hands.

Well, yes.

I'll just leave this here:

Hygiene associated with the product has been questioned in research by the University of Westminster Trade Group, London and sponsored by the paper towel industry the European Tissue Symposium

[–] Kbobabob@lemmy.world 17 points 2 weeks ago (5 children)

It's ok to be cautious, but if the data is accurate then it doesn't matter much.

This has been debunked btw. Fwiw, there is a huge behind the scenes fight between big towel and big airblow.

I'm not kidding. But basically drying via air is much more hygienic in actuality.

I just wish people would know how to use paper towels so that they don't end up wasting huge piles of them for nothing. 1 sheet is enough. You don't need 5. Do it like this:

  • After washing your hands, brush excess water off each hand using your other hand. Your hands should not be dripping wet when you reach for the paper towel.
  • Take a single paper towel. Don't scrunch it up, and don't just clasp the towel. Use all parts of the paper towel to deliberately wipe your hands. The paper towels are quite absorbent. They don't need to be 100% dry to remove the water from your hands.

The end. If you do this, your hands will not be wet. You will not need a second paper towel.

[–] sem@lemmy.blahaj.zone 20 points 2 weeks ago

You missed something. You gotta fold the paper in half. The capillary action will trap more water in between the folded halves than it could unfolded.

The Shake & Fold method. There was a Ted Talk!

[–] 0x0@lemmy.dbzer0.com 17 points 2 weeks ago

I mean if you need two or three, that's still way better than grabbing 20.

My biggest issue is the decibel level. I can hear, for now, but the decibel level on those things makes one of my ears feel like it’s being blasted out of my skull and induces ringing.

I use the paper because it doesn’t hurt my ear.

Yes, I’ve seen a doctor, it simply is what it is and my only recourse for that ear is to wear ear protection. In any public restroom, apparently.

[–] Trainguyrom@reddthat.com 19 points 2 weeks ago (6 children)

My daughter is extremely noise sensitive and can't handle the noise of those either. After a really rough 2 hour drive involving 3 gas station stops because she refused to even try to use one due to the auto-flushing toilet my wife suggested "making an app to track public bathrooms with air dryers and autoflushing toilets" and I've been debating if I want to start tagging every public bathroom I visit on Open Street Map with the toilet flush mechanism and existence of air dryers. And if i did so I'd probably also mark what changing table amenities are available and if there's more/less changing table amenities in the womens' or mens' rooms.

How can it spread germs if the germs are 99% gone after having washed your hands with soap? We're assuming people aren't washing their hands properly, right?

[–] bluewing@lemm.ee 31 points 2 weeks ago (5 children)

Yes you can assume all people don't wash their hands correctly.

Some microbes will survive the hand washing process, and need to be removed by drying. Those Dyson air blades collect germs from water from washed hands and the toilet environment, then blow the germs around. It's gross.

Also, Mr Dyson is a fucking dick.
