To Safely Clean Your Computer Monitor using Water will help keep your computer, its monitor and other peripherals clean and maintain your system in good health and yours also. Computer monitors quickly attract and collect dust, grease, grime, fingerprints that can reduce its clarity and effectiveness. Depending on your environment where your computer is located, like sn home office, house with pets, you may need to clean more often since more dust and grease or grime may be more aggressively attaching to your computer. Computer are devices that can have a lot static, especially in heated environments and static electricity will attract undesirable elements.

Flat screen computer screens have special coatings to help with contrast and glare. Using chemicals on these screens can cause permanent damage to this special coating.


For best results only use water and a lint free cloth. Avoid detergents and other product that may contain harmful chemicals. If you have hard to remove grime, you can use a mixture of white vinegar and water, preferably distilled.

The cloth you use must be soft with no hard or sharp fibers as these can scratch the surface of flat screen monitors.

Cleaning Instructions For Monitors

To safely clean your monitor using water, follow these instructions.

  1. Always turn off your monitor and your computer or your laptop to ensure that no electrical power in coming into the devices.
  2. Dampen a lint-free cloth with water. Don’t over wet the cloth since running or dripping water can run down into the computer (laptop) or get into the electrical circuitry of the monitor and permanently damage the computer or monitor. Never use a sprayer as the water can get into the electrical circuitry.
  3. You use caution when cleaning the monitor. Don’t apply too much pressure or rub too hard if you encounter hard to remove grime. Rubbing too hard can permanently damage the surface of the monitor.
  4. Use diagonal motions either from top down or vice versa. Avoid using circular motions or rubbing repeatedly back and forward.
  5. Gently wipe the screen dry with a lint free cloth. Again wiping in a diagonal motion instead of in circles.
  6. To clean the plastic or aluminium (Apple) case of the monitor or laptop, you can use normal household products or you can stick to water.

Following these simple steps will ensure that you continue to enjoy your computer for many years and also reduce eye strain as a result of a grimy computer screen.

      Thanks, absolutely. This is what I usually do because chemicals can seriously damage the surface of the TV screen.
