To clean your keyboard properly, turn off your computer first then unplug the device from its power source. Use compressed air to remove dust particles from between keys, then use dampened lint-free cloth lightly dampened with warm water to wipe any residues from the surface of the keyboard. Make sure never to spill water inside of the device while cleaning it.

Your ergonomic keyboard should be placed directly in front of your monitor so that your arms are at an angle of about 90 degrees when you type on it.
