4. Cell Phone
On that note, you wouldn’t believe how filthy our cellphones can become. This will probably freak you out, but studies say that phone screens are generally dirtier than toilet seats. Ummm, ew! Don’t fret — you can keep your phone clean by investing in both a screen protector and case to limit the amount of germs your phone comes in contact with. Additionally, you can use a cleaning spray on some paper towel to wipe down your screen, as well as the rest of your phone.
