Cleaning the Computer Case
Follow all safety precautions in General Cleaning Safety Precautions on page 38 before cleaning the
computer.
To clean the computer case, follow the procedures described below:
●
To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
●
For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with
a cloth or swab dampened with clear water.
●
For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will
evaporate quickly and not leave a residue.
●
After cleaning, always wipe the unit with a clean, lint-free cloth.
●
Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents
and limit the airflow.
