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 using compressed air, to prevent dust and
debris from getting into your eyes.
Cleaning products
Use the following products to safely clean your computer:
● Dimethyl benzyl ammonium chloride 0.3 percent maximum concentration, usually in the form of
disposable wipes in a variety of brand names.
● Alcohol-free glass cleaning fluid
● Water with mild soap solution
● Dry microfiber cleaning cloth or a chamois (static-free cloth without oil)
● Static-free cloth wipes
CAUTION: Avoid strong cleaning solvents that can permanently damage your computer. If you
are not sure if a cleaning product is safe for your computer, check the product contents to make
sure that ingredients such as alcohol, acetone, ammonium chloride, methylene chloride, and
hydrocarbons are not included.
● Fibrous materials, such as paper towels, can scratch the computer. Over time, dirt particles and
cleaning agents can get trapped in the scratches.
