hospital stuff tends to have resistant bacteriaxon just about anything and the number of types just increases with the use of strong antibacterian cleaners.
as a tech guy I am somewhat fond of having reasonably clean devices. I am far from obsessed but I clean my devices more carefully than most of my other home stuff, kitchen utensils included. When I clean my laptop I use dedicated things like antibacterian wet wipes, antistatic for the screen, compressed air, etc. My wife, who is the cleaning guardian of the house, doesn't care as much for her laptop. My Mac pro was taken to Apple service with the famous keyboard issues of newer models, occasion on which they also remarked how dirty my keyboard is. It did have non dirt related issues, though if my reasonably cleaned keyboard had such an impressive amount of dirt that prompted Apple care guys to say it out loud, I shudder to think about my wife's laptop.
