How To Clean an LCD Screen

Cleaning screen

A liquid crystal display screen, commonly known as an LCD screen, is a thin and lightweight monitor found in a variety of appliances.  Computer monitors and television screens are examples of LCD screens, as well as calculators, video games, watches, cameras, and other gadgets.  An LCD screen projects light out of the screen.  If the screen is dirty, the light is diminished and the image quality is compromised.  Here is how to clean an LCD screen for clearer and brighter pictures.

  1. Turn off the unit and examine your screen.  When the screen is on, the brightness and the visual detail make it difficult to see tiny smudges and dirty spots.  Turn the LCD screen off and shine a light to the screen.  Look at the screen to notice dirty areas.  If at first you don’t see a spot to clean, visually scan the entire screen.  Examine the screen in sections.  Move your eyes from top to bottom or left to right, then move to another section.  This makes you notice subtle grime and dust that have accumulated on your screen.
  2. Brush the screen.  Using a fine brush, dust the LCD screen to remove loosely attached dust and dirt.  An LCD screen usually accumulates a thin layer of dust, and removing this layer first decreases the amount you have to clean later.  Make sure to dust the screen lightly to avoid scratching its surface.
  3. Prepare the cleaning solution.  Use a safe cleaning solution for cleaning your LCD screen.  Refrain from using corrosive chemicals that may ruin your screen such as alcohol, acetone, and strongly acidic solutions.  Test the cleaning solution with other unused LCD screens and see its effects upon the screen.  Read a cleaning solution’s description to know whether it is safe to be used on an LCD screen.  Read the instructions written on the cleaning solution to know how to properly use it.  Some solutions require to be diluted in water, and the wrong dilution may interfere with its cleansing properties.
  4. Spray the cleaning solution.  Pour the cleaning solution into a clean spray bottle.  Shake it to mix the solution adequately.  Place the bottle 6 inches from the screen.  Spray a fine mist of cleaning solution to the screen until a thin layer is formed.  Spray one section at a time.
  5. Wipe the LCD screen.  Wipe the screen using a soft, smooth and clean cloth.  Alternate spraying the screen with wiping the screen, one section at a time.  Never use tough and abrasive cleaning materials such as sandpaper or a rough towel.  An LCD screen is easily ruined by inappropriate wiping material. 
  6. Leave the LCD screen to dry.  Set aside time for the LCD screen to dry.  Don’t dry it using a hairdryer because this may damage the LCD screen.  30 minutes is usually enough to make an LCD screen dry.  Afterwards, turn the monitor on to see whether the image quality has improved.
  7. Maintain its cleanliness.  An LCD screen gathers dirt and dust, but the amount of dirt that accumulates on it is lessened by handling and positioning it properly.  Refrain from touching the screen with your bare hands, because this leaves fingerprints and skin oils to the screen.  Avoid placing the screen near a window or in places where dust gathers. 

LCD screens require regular cleaning to keep the pictures clear and bright.  Notice whether an LCD screen needs cleaning, and clean it whenever it becomes dirty.  Avoid dirtying an LCD screen to lessen the number of times you have to clean it up.  For maximum results, inform other people who use the LCD screen about the proper way of handling and cleaning it.
