As the most frequently touched items in daily life, cell phones have a high chance of attaching bacteria and viruses, so you need to clean and disinfect them when you get home after going out to use them. Whenever you get home, you can turn off the power of the phone, wait for the phone to cool down thoroughly, dip the appropriate amount of 75% alcohol evenly sprayed on a cotton ball or sterile soft cloth, wipe the phone screen, back and sides, the phone button gap, charging interface and other parts from top to bottom in the same direction. Leave the phone for 5 minutes and wait for the alcohol to evaporate on the surface of the phone. In addition, you can also use other disinfection products that are not harmful to electronic products, and do a good job of hand hygiene after disinfecting the phone.
