Physical Maintenance

Don’t touch the screen.
The oils from your fingers will leave fingerprints that are hard to remove. Avoid touching the screen if you can. To clean an LCD screen try a dry cloth for dust or a moist cloth for stuck-on stains. If the dirt is persistent, pick up an LCD cleaner or cleaning cloths sold at most computer and electronics stores. Don’t spray anything directly on the screen, and do NOT use regular surface cleaners. Make sure you only press gently, as pressing too hard may damage the screen.
