Difficulty: Moderately Easy
Step1
Zwipes Microfiber Glass Cloths
Get a microfiber cloth. I preferably use a Zwipes Glass Cloth since the iPhone screen is glass. These are usually available at your local automotive store such as O'Reilly's, Wal-mart ect.
Step2
Wash your hands very thoroughly.
Step3
Hold the Black Sleep/Wake button until the turn off phone option is available. Then use the slide bar to turn off the phone.
Step4
Take one of your new microfiber cloths and wipe the screen of the phone very very thoroughly with one side of the cloth. Make sure you remove excess oils, and debris. Make one final wipe from the inside out.
Step5
Wipe down the rest of the phone with the other side of the microfiber cloth.
Step6
Keep the other cloth near your iPhone. I keep mine by the dock on my night stand. Wipe it down in the morning before use of the phone. It will be clean like new every day.
