Hotel Light Switches
What's one thing that everyone touches in a hotel room, but no one ever cleans? It's the light switch, and it's home to lots of germs. Think about it: People might wash their hands once they get inside the room, but the first thing they touch (after being on germy planes and trains) before reaching the bathroom is the room's light switch. A recent study by a University of Houston researcher found that the main light switch was the dirtiest surface in the hotel rooms tested and often contained high levels of fecal bacteria.
