Light switches are often overlooked but they can actually harbor a lot of bacteria. We touch them all the time, so they accumulate germs from our hands. The smooth surface of the switches can trap dirt and oils, creating a breeding ground for bacteria. Even though they may not seem dirty, they are actually quite unsanitary. That's why they are number four on our list of dirty household items. Number four, light switches. Often overlooked, light switches are a hotspot for bacteria, accumulating germs from our hands every time we flip them on or off. These small, everyday devices are touched countless times throughout the day, making them a prime candidate for harboring harmful microorganisms. The smooth surface of most light switches can easily trap dirt and oils, creating a breeding ground for bacteria. While they may not seem as dirty as other household items, their frequent use places them at number four on our list.
