9 Routine Care
General cleaning safety precautions
● Never use solvents or flammable solutions to clean the computer.
● Never immerse any component in water or cleaning solutions; apply any liquids to a clean cloth
and then use the cloth on the component.
● Always unplug the computer before cleaning the keyboard, mouse, or air vents.
● Always disconnect the keyboard before cleaning it.
● Wear safety glasses equipped with side shields when cleaning the keyboard.
Cleaning the chassis
● Follow the safety precautions in the Maintenance and Service Guide for your workstation before
cleaning the computer.
● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
● For stronger stains, use a mild dish washing 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 required because the alcohol
evaporates quickly and does not leave a residue.
● After cleaning, always wipe the computer 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.
