An Expert Explains Just How Dirty Smartphones Are and, How to Clean Them – Properly

"The simplest and most cost-effective method would be to wipe your phone down, using a microfiber cloth and alcohol wipes," Demana explains.

How to Sanitize Your Phone Using a Microfiber Cloth and Alcohol Wipes: To start with, clean your phone with a microfiber cloth. Doing so removes germs, dust, mold, and viruses that may be present on your phone. Once you've wiped your screen clean, grab an alcohol wipe and wipe the front and back of your screen.

Points to Remember: Avoid using aerosol or alcohol spray, as the moisture can damage your phone's headphone and charging ports, as well as your speakers – not to mention your phone's internal system.
