Computer equipment can become coated or filled with dust, pet hair, nicotine (tar) stains and dirt. If your computer is still under a service warranty, the best course of action is to have the internal components professionally cleaned and serviced by the manufacturer or dealer. If not, it is possible to safely clean some computer equipment and devices at home or in the office.

2. Clean the outside of the computer case with a damp cloth, then touch something metal to eliminate static charge.

3. Remove nicotine stains from computer cases by dampening a cloth with a small amount of ammonia and rub until the stain disappears.

4. Open the computer case according to the instructions in your owner's manual.
