How To Clean Your Cellphones & Laptops, From An Expert

With the continued spread of COVID-19, you've likely heard from the CDC that washing your hands is one of the best ways to protect yourself1 from infection. Along with hand-washing, they recommend disinfecting frequently touched surfaces, which can include cellphones and laptops. 

Apple recently updated their webpage to inform users that it's OK to use a 70% rubbing alcohol wipe on the surface of your iPhone. Maker told us, "That's the best thing to do in terms of killing germs." 

In case your local store has run out of disinfectant wipes, "applying rubbing alcohol on a flat-weave microfiber cloth, and running it along the screen of your phone," has the same effect. 

Just because the backs of our phones don't touch our faces doesn't mean we should neglect cleaning them. To make sure every aspect of the device is clean, Maker uses "two-step disinfection" to clean both the front and back of the phone, as well as the interior and exterior of the phone's case.

If you're working from home or your school is canceled for the time being, your laptop is (hopefully) less exposed to germs. However, if you're still going to the office or working from coffee shops, wiping down your laptop daily is good practice. 

"Your phone is like your third hand," Maker said. "If we're washing our hands several times a day, then we should be doing the same with our phones."

Under most circumstances, cleaning these devices once or twice a week is sufficient. Under current conditions, though, if you've been using your cellphone in public, she recommends cleaning it daily. 

This is because, according to infectious disease specialist Sandra Kesh, M.D., "most people's cellphones are teeming with bacteria and viruses. Plain and simple, they're gross."
