How to Clean your LCD Monitor:

What does LCD stand for?
Liquid Crystal Display, mostly used in flat screen monitors and laptop screens.

Why should I worry about cleaning my LCD screen?
One of the most expensive components of a computer system or laptop is the LCD monitor or screen. LCD screens are easily susceptible to damage and scratches, so it's a good idea to make sure you clean it correctly.

Can I use any type of cleaning solution on my LCD screen?
No, using alcohol or ammonia - based cleaners repeatedly may cause permanent damage to the LCD. Over time using these types of cleaners could cause the surface of the screen to yellow. It can also make the screen brittle and eventually cause cracking on the screen surface.

NOTICE: The following cleaners are unacceptable:

  • Acetone
  • Ethyl alcohol
  • Ethyl acid
  • Ammonia
  • Methyl chloride

What types of cleaners are acceptable?
Vinegar (mixed with water)
Isopropyl Alcohol
Petroleum Benzene

What are some of the basic supplies needed to clean an LCD screen?

  • A soft cotton cloth. When cleaning the LCD screen it is important to use a soft cotton cloth, rather than an old rag. Some materials, such as paper towels, could cause scratches and damage the LCD screen.
  • Solution of water and isopropyl alcohol. This solution can be used along with the soft cotton cloth.
  • Computer wipes. Only use these if they specifically state on the package they are designed for LCD laptop screens. Computer wipes can come in handy for fast clean-ups or when you want to avoid mixing up a cleaning solution yourself.

How do I clean the LCD surface properly?

  • Do not spray any liquids on the LCD screen directly, and do not use paper towels, this can cause the LCD screen to become scratched.
  • Always apply the solution to your cloth first, not directly to the parts you are cleaning. You want to avoid dripping the solution directly into your computer or laptop.
  • Stroke the cloth across the display in one direction, moving from the top of the display to the bottom.
