Washing your hands is one of the most helpful ways to kill off germs that could make you sick. But things that people usually touch all the time should also be cleaned just like the smartphone!

Based on a study, germs could live in plastics and stainless steels for two to three days. If people had touched those surfaces, hands could carry those bacteria. Can you imagine how dirty your phone is?

So what’s the proper way of cleaning your phone? First, turn it off before you clean it. Don’t use cleaning sprays and bleach because it might put moisture on the phone. Wipe it with a wet soft cloth or wipes with 70% alcohol.

Don’t forget to clean the phone case too! And then wash your hands as usual with soap and water to keep the germs away.
