A guy I used to work with back in my tech support purgatory would bring those alcohol pads they use at clinics, and wipe down the keyboard, mouse, phone, headset, the buttons on the monitor, and even part of the desk. He also had a bottle of store-brand purell and kept rubbing his hands with it throughout the day. When he went to the bathroom, he would of course wash his hands, but he'd also use a towel to open the door, throwing the towel away on the way out.

He moved on to become a nurse.
