When’s The Last Time You Cleaned Your Light Switches?
Think of how many times you press light switches ever day. They accumulate a lot of germs over time. According to a study by the University of Houston, hotel light switches contain 112 colonies of bacteria per centimeter. Scientists at Simmons College claim that switches have as many germs as a trash can.
In these studies, bedside lamps held more bacteria than wall light switches. In hotel rooms, these buttons are some of the dirtiest objects besides TV remotes. Disinfect light switches every two weeks, and do so more often if someone is sick.
