They've got those at Alton Towers, they feel really weird but they get your hands dry really really quickly.
All the same bacteria would be present on the paper towel dispenser, the door handle, etc.If you have an Emerald account run a search...
In essence, hand dryers, even the most expensive ones have the effect of moisture remaining in parts of the machine, bacteria love moisture, and lots ofÂ machines do not blow air that is hot enough to kill pathogenic bacteria, plus a lot of people do not wash their hands properly, and so hands with faecal matter and / or bacteria enter the machine, and some of that matter can get blown onto your hands.
You can imagine what drying your hands on a re-usable towel or your trousers can do...Not good.
Despite the negative environmental consequences, drying your hands with dry paper towels is your best bet.
Yeah, they never really seemed to dry in time for the next person... And it was even more disgusting if someone wiped their... nose on them...Anything's better than the re-usable towel on a roll that I grew up with.Â Those were just gross.
What an odd topic btw.
