I hope these things are autoclaved and not just disinfected.

No matter how clean operating rooms are (which can vary a lot), it's never perfectly sanitized.
A cheap way to get many surfaces agent free would be a nice additional safety measure.
Sterilizing those often increases disease spread. By default, they are covered with a microbial community that can outcompete things that are human pathogens.
If you sterilize it, then you’re either leaving a coating of food (mostly dead skin cells) for pathogens to eat, or a coating of nasty poisons that strip the protective barrier off people’s skins, which undermines their ability to fight off what pathogens they do end up touching.
Probiotics can be applied to mitigate undesirable bacterial growth after sanitizing [1].
- medical equipment: handles for scalpels, syringes, operation tables... All those things we need to clean again and again.
- passage ways: doors, handles, stairs handrails, subway grab bars... All the things that propagate infections in very dense populated areas.
- research fabs: hazmat suits, protection googles, fum hood protections,... All the stuff you want to make sure don't end up cross contaminate your batch or escape.
So it's still very useful.
