Actual science is always good, but I’d like to see data on them with hourly vs daily vs weekly vs monthly washroom cleaning, and the same data on regular hand dryers and as well as paper towel.

Bet the airblades are best with a quick cleaning cycle, and worst with a slow cleaning cycle (except for paper towel if the cleaning cycle is slow enought; ‘no paper towel, dry your hands on what you can’ is certainly the least best option)
