How do I Clean my Device?

Regular Cleaning of your device:

Clean the case with a soft damp cloth. Damp means wrung out until

almost dry, never dripping. If you purchased a keyguard, wash it often

in hot, soapy water.

Cleaning the Display area: 

Clean the display with the same kind of product you use for windows.

To avoid scratching the display, use a soft cloth and spray the cleaner

directly onto the cloth, not the display. If you notice a film over the

screen after you have cleaned it, try a different window product. You

can also clean the overlay protector with the window-cleaning product.

Disinfecting: 

To disinfect your equipment, mix ¼ cup vinegar with 1 cup water. Wipe

all equipment with a cloth dampened in this mixture. Allow the

equipment to air dry.
