After hours of active use, your iPhone's screen will become filled with more greasy fingerprints and smudges than the front doors of your local McDonalds. How can you see through all that film? Wipe if off? No, be creative. Express your inner artist. Let your fingers inspire you. Rub your iPhone's slippery glass surface in delicate strokes, forming shapes and contours. Create images and silhouettes from the deposited facial oil. Where others see a smudgy screen, I see the face of a clown.
Now spray Windex onto a sheet of paper towel, lightly dampened. Then clean your filthy screen, and get back to work. Stop wasting time.
