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)
