When I’m not busy writing how-to articles, I work for a large chain of retail stores that recently replaced its DOS-based cash register system. The new registers have LCD touch-screens, and every time I start a shift at the register, I have to fight my gag reflex, which gets all excited by the greasy fingerprints (and fingersmears and fingersmudges and sometimes fingerchunks) the last person left all over the screen that I’m expected to touch. Our managers have instructed us to clean the screens with window cleaner and paper towels, so I do (I didn’t pay for the registers, after all), but deep down in my heart I know it’s wrong. LCD screens are not glass, and they require different cleaning methods than glass. Fortunately, except for the need to perform a tiny bit of simple chemistry, cleaning an LCD monitor is just as easy as cleaning a glass-screened CRT monitor. My latest article goes over all the steps. Maybe someday, if I’m feeling charitable toward the Man, I’ll forward the link to my employer so they’ll know how to clean an LCD monitor without gradually destroying it.
