Clean Your Cell Phone

You can clean your cell phone with a microfiber cloth and cotton swabs, compressed air, or a UV light device. It is important to keep your phone clean because recent studies have shown that there are about 25,000 germs per square inch on most cell phones. That means your phone has more germs than a public toilet.[1]

Steps

Cleaning Your Phone Manually

  1. Turn off your phone and disconnect any power supply. Remove the case and any screen protector. If you have cracks in your screen do not remove the protector.
  2. Remove your battery if you are able to do so.[2] This may, however, invalidate your warranty.
  3. Clean your keypad, if you have one, with a dry cotton swab. Clean the interior of your phone very carefully with a clean, dry cotton swab.
  4. Replace your battery and reassemble your phone. Using a lint free microfiber cloth wipe off the back of your phone. You may need to dampen a portion of the cloth with a solution of 40 % alcohol to 60% distilled water to clean any stubborn spots.
  5. Use the microfiber cloth to wipe your screen using long, vertical strokes. You may also use the dampened portion of the cloth on your screen if some smudges remain. Wipe your screen again with a dry microfiber cloth.
  6. Clean the case, inside and out, with the dampened microfiber cloth. Use a cotton swab, lightly dampened with the alcohol mixture, for the corners and any crevices. Allow your case to dry completely before returning it to your phone.[3] [4]
    • Use a high quality leather cleaner for a leather case. Allow your case to dry completely before putting it back on your phone.

Cleaning Your Phone with Compressed Air

  1. Turn off your phone and disconnect any power supply. Remove the case and any screen protector. If you have cracks in your screen do not remove the protector.
  2. Clean the exterior of your phone including your screen and keypad. Holding the can several inches from your phone begin to blow over the keypad using rapid back and forth motions. Blow over your screen and the back of your phone.[5]
  3. Remove your battery if you are able to do so.[2]This may invalidate your warranty.
  4. Blow out the interior of your phone, if you have removed your battery. Keep the can moving at all times. Make sure the nozzle does not make contact with your phone to avoid any drips of moisture.
  5. Replace your battery and reassemble your phone.
  6. Blow off the inside and outside of your case. You may now return your phone to your case.

Cleaning Your Phone with a UV-C Light Device

  1. Plug the UV-C unit into a wall outlet. Lift the lid and place your phone inside.
  2. Plug in your charging cord if you wish to charge your phone while it is cleaning. Certain UV-C devices are better designed for this than others[6]
  3. Close the lid and sanitizing will begin automatically. When the blue indicator light comes on, after about four minutes, the cleaning is complete
  4. Lift the lid. When your phone is sufficiently charged, disconnect the phone charging cord and remove your phone from the unit. You now have a germ-free phone.
