Also the return of paper towels for hand drying.
I hate those stupid air dryers. Most of them barely do any better than just shaking your hands in the air, because they’re simply spraying your clean hands with all of the shit and piss particles that are floating in the air.
Would rather have some cheap paper towels so I can dry my hands, and use the towel to open the door before throwing it in the trash.

I saw one of these once where someone scratched “4. wipe hands on pants” on the instruction panel.
The trick is to shake dry in the sink, then rub the moisture up past your wrists onto your forearms, creating a thin layer. Then use the dryer, repeating the rubbing motion spreading the moisture out until it’s gone.

This is the real problem. Apparently, the Dyson air blades are the worst: https://arstechnica.com/science/2016/04/dyson-dryers-hurl-60x-more-viruses-most-at-kid-face-height-than-other-dryers/
Additionally, my understanding is that a lot of the cleaning done by washing your hands is mechanical, and using a paper towel with a slightly rough and absorbent surface scrapes off all the stuff that has been loosened by washing with soap and water.
Outside of antibacterial or germicidal soaps, the cleaning action of washing with soap is 100% mechanical. Soap molecules are asymmetrical and have one side that’s hydrophilic and one side that’s hydrophobic which, when used with water, creates a nifty mechanism that picks up crap on one side and catches a ride on the water molecules with the other side.
Isn’t basic soap also destroying the lipidic membrane of most bacteria? It doesn’t need to be specific antibacterial soap for that.
They’re pretty bad. Putting your hands down in a hole and spraying water all over isn’t real sanitary. I’ve seen some that are really dirty inside!
The new generation doesn’t use this bad design anymore. The Dyson Airblade V is just a box with two sharp edges that blows the water right onto your pants and the Airblade Wash+Dry works in a similiar way with a little bit sleeker design. Both of them have hepa filters too, so from a hygienic standpoint they are much better than their old airblades and the clones that filled the market.
They’re nice, but I’ve never seen anyone use them properly. Then again I rarely see people wash their hands properly either…
You’re a supposed to move your hands out slowly and the air blade wipes the water away.
