Before the widespread use of flat LCD and plasma technology, the reigning computer monitor display technology was CRT (Cathode ray tube). These monitors are large and clunky, not slim like many new monitors. Cleaning a CRT monitor can be done the same way as cleaning an LCD, although LCD screens are often more fragile.

Step 1

Turn off your CRT monitor and unplug it from its power source. Use a dust rag to take off any loose dust on the screen.

Step 2

Dampen a soft rag with water and gently scrub the screen. Use a dry rag to dry any moisture left behind.

Use an electronic wipe made for cleaning monitors, if you wish. Most CRT monitors can be cleaned effectively without them.


  • CRT monitors are somewhat more durable then LCD and plasma screens, but you should still be wary about using normal glass cleaning products on them.
  • Often, a simple dusting with a clean rag will be adequate to clean off a CRT screen.
