Cleaning the Screen and Mirrors

The best way to clean screens and mirrors is with clean, dry, compressed air and try to blow off the debris. If this does not work (a finger print, for instance) use a good quality optical cleaning solution and lint-free paper wipes or cheesecloth. Note: Apply the liquid cleaning agent to the tissue first; don’t spray it directly on the mirror or screen. This will sometimes appear to leave a light residue, but it will buff off, leaving a streak-free mirror. Because the mirrors are front- surface mirrors, use care when cleaning them.

Some representative cleaning products are:

•Zero Charge Screen & Keyboard Cleaner, made by Tech Spray, Amarillo, Texas; (803) 372-8523

•Klear Screen Laptop & Computer Screen Cleaner, by Merridrew Enterprises, Danville, California; (510) 838-8774

•Sparkle, made by Paulson and Roles, Portland, Oregon; (503) 282-3289

The inside of the screen is harder to clean; usually the problem on the inside is finger prints. Do not use cleaning products on the inside of the screen. Instead, use a little isopropyl alcohol on a piece of cheese cloth, and don’t press hard. Don’t buff it off. Let the alcohol evaporate.

CAUTION The screen is a laminate of two pieces. If excess liquid runs down the screen and collects at the bottom, it can wick up between the two parts. This is nearly impossible to correct.
