Other cleaning systems use tissue wipes that are impregnated with a cleaning agent. The solvent is designed to evaporate quickly, leaving the screen surface smear free. The surface of the keyboard keys are cleaned in much the same manner as the screen display. Care should be taken to prevent excess downward pressure on the keys whilst cleaning. Avoid the use of abrasive or corrosive fluids that might etch the letters of the keys.
Dust is removed by use of portable vacuum cleaner, or little brush which has an air pump attachment.
Screen burnout is a term used to describe damage caused to the inside surface of the screen display. The inner surface of the screen is coated in a phosphorous material that emits light when struck by an electron beam. This might take several days or weeks to occur. Damage to the screen cannot be repaired. Damage is visible by turning of the display, and inspecting the screen surface closely.
