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.
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.
Regular soap does also kill bacteria with those hydrophobic sides of its molecules by breaking a bacteria or virus’ lipid membrane. I would argue this still a mechanical process though. Antibacterial soaps use a specific chemical, Triclosan, that binds with enzymes within the bacteria that prevent it from reproducing.
One of the positives from the covid pandemic is a lot of bathroom doors can be opened with your foot now.
Also the return of paper towels for hand drying.

The only dryers I like are the Dyson ones the air blade ones.
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!

Isn’t basic soap also destroying the lipidic membrane of most bacteria? It doesn’t need to be specific antibacterial soap for that.
