How to clean an LCD screen

  1. Turn off the device. If the screen is dark, it will be easier to see the areas that are dirty or oily.Turning the device off also prevents you from accidentally pushing buttons you don’t actually want to push, which happens a lot when cleaning touchscreen devices like tablets, iPads, etc.
  2. Use a dry, soft cloth and very gently wipe the screen. Amazon.com sells microfiber cloths and dry erasers, both equally fantastic choices.See Tip #1 below for kinds of cloths to avoid.
  3. If the dry cloth did not completely remove the dirt or oil, do not press harder in an attempt to scrub it off.Pushing directly on the screen can often cause pixels to burn out, especially on laptop displays, desktop monitors, and LCD/LED TV screens. This isn’t so much an issue on screens designed to be touched, like phones and tablets, but be careful nonetheless.
  4. If necessary, dampen the cloth with distilled water or with an equal ratio of distilled water to white vinegar.Many companies also sell small spray bottles of special cleaner for flat screens. Bryson Industries makes this Screen Cleaner Kit people seem to like but honestly, the 50/50 white vinegar and water mix is probably just as effective.See Tip #2 below for types of products to avoid.
  5. The plastic edge that surrounds the screen can be cleaned with any multipurpose cleaner but take care to avoid contact with the screen itself.

Tips & More Information

  1. Avoid using paper towels, toilet paper, tissue paper, or something like your shirt to wipe the screen. These non-ultrasoft materials can scratch the display.
  2. Avoid cleaning products that contain ammonia (like Windex®), ethyl alcohol (Everclear® or other strong drinking alcohol), toluene (paint solvents), as well as acetone or ethyl acetate (one or the other is often used in nail polish remover).These chemicals can react with the materials that the flat screen is made of or coated with, which could permanently discolor the screen or cause other kinds of damage.
  3. Never spray liquid directly on to any screen. It could run inside the device and cause damage.
