How to Avoid Fingerprints on Touch Screensby Gemma Craig
Touch screen devices, such as smartphones and tablets, are useful due to their convenience and maddening due to their propensity towards smudging. Because your fingers are naturally coated with oil, you leave behind smudges and prints every time you touch your device's screen, eventually causing the LCD to appear cloudy or dirty. If you're tired of constantly wiping the marks off your touch screen, you can take a couple of steps towards drastically minimizing the amount of prints you leave on the device.
Wipe your touch screen clean using a microfiber cloth. Move the cloth in even, slow motions, applying gentle, steady pressure. Rub the screen as if you are polishing it until all the fingerprints and smudges are gone.
Place a fingerprint-resistant screen protector onto the device. This thin piece of plastic not only protects the screen from scratches, but also resists skin oil, reducing the number of prints left behind. Peel back part of the cover from the screen protector's "clingy" side and place the exposed part of the protector onto the touch screen. Slowly peel the rest of the backing off the protector while smoothing it down onto the touch screen. Smooth out any air bubbles that appear.
Put a Phone Finger on the finger you use to touch your touch screen. A Phone Finger is a protective sleeve that you wear over your finger like a glove. It is specially designed so the touch screen will still register your touch, even though there is a barrier between your skin and the glass.
