How Dirty Is Your Phone

How many times a day do you touch your phone? Now, how many times do your kids grab your phone? Have you ever really thought about how dirty your cell phone could be? It’s true, every day we are in contact with dirty things – doorknobs, our desk, restrooms or even shaking hands. The problem is that when we come in contact with these germs, they are transferred straight to our phones … leading straight to our face.

Dirty Stats

Here’s a dirty stat: every square inch of your cellphone contains roughly 25,000 germs, making it one of the filthiest things you come in contact with on a daily basis (more than a public restroom!).

  • Phone: 25,000 bacteria per square inch (BPSI)
  • Toilet Seat: 1,201 BPSI
  • Kitchen Counter: 1,736 BPSI
  • Pet Food Dish: 2,110 BPSI
  • ATM: 4,500 BPSI
  • Doorknob: 8,643 BPSI

How Dirty is Your Phone?


According to a study from the University of Oregon, more than 80 percent of the bacteria on our fingers is also found on our screens.

Wash Your Hands

Prevent the common cold and flu by regularly washing your hands with soap and clean, running water. This is one of the most important steps to avoid getting sick and spreading germs. How many people do you know who take their phones into the bathroom? Feces is one source of germs like SalmonellaE. coli O157, and norovirus that cause diarrhea, and it can spread some respiratory infections like adenovirus and hand-foot-mouth disease.

Other germs, like Staphylococcus, Micrococcus and Bacillus can also be found on cell phones. According to the CDC, removing germs through handwashing therefore helps prevent diarrhea and respiratory infections and may even help prevent skin and eye infections.

Cleaning Your Phone

Bacteria can survive on your phone for many days. When it comes to cleaning the screen, it is best to check the manual. Never spray any cleaning solution directly onto the phone, it is usually best to use a disinfectant wipe that is bleach free, then rub the phone with a soft cloth. Yahoo Tech suggests you can keep your screen clean by using antibacterial wipes like ZAGG’s or a device like the PhoneSoap Charger, which uses UV light to sanitize the phone while it’s plugged in.
