Follow instructions in the manual or in help files that came with the computer or other
hardware devices
Before cleaning anything, unplug it from the electrical wall socket

When to clean a computer

  • Computers do not need to be cleaned too often if they are kept in a clean environment
  • Clean the computer when it looks dirty or when a device (like a mouse) does not work right The two things that need the most cleaning are the screen and mouse

Materials needed for cleaning a computer

  1. Most cleaning materials can be found in a home or any store
  • soft lint-free cloth’s
  • soapy water - a drop or two of dish washing detergent in a gallon of water

  • water spray bottle to hold the soapy water
  • used fabric softener cloth
 2. You may have to buy the following at a computer or office supply store

Cleaning the case and other plastic surfaces

  • Use a damp lint-free cloth to clean the case
  • Wipe the surfaces with the damp cloth
  • For more difficult marks use the eraser. An ink eraser works best
  •  For cracks and tight places, use a slightly damp cotton swab

Cleaning a monitor's screen

  • Wipe the screen with the damp lint-free cloth
  • Use a dry cloth to dry the screen
  • Use fabric softener cloth to help remove static charges on the screen 
  •        static charges attract dust to the screen
  •      a fabric softener cloth has anti-static chemicals on it
  •      wipe the screen very lightly with the used fabric softener cloth
  •     Do not use a fresh fabric softener cloth. It will leave streaks.

  • o Blow out the inside of the mouse to remove any dust
  • o Put the mouse back together after it has dried

Inside the computer's case

  • The inside of the computer rarely has to be cleaned and it is not recommended that this be
  • done
  • If you must clean inside your computer follow the following precautions:
