Cleaning your computer

Use the following products to safely clean your computer:
● Dimethyl benzyl ammonium chloride 0.3 percent maximum concentration (for example, disposable
wipes, which come in a variety of brands).
● Alcohol-free glass-cleaning fluid
● Water with mild soap solution
● Dry microfiber cleaning cloth or a chamois (static-free cloth without oil)

CAUTION: Avoid strong cleaning solvents that can permanently damage your computer. If you are not sure
that 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 in the

Fibrous materials, such as paper towels, can scratch the computer. Over time, dirt particles and cleaning
agents can get trapped in the scratches.
