Orloff started ComputerBath, a company that offers a line of products designed to cover most cleaning needs. Start your cleanup by shutting off power. Dust computer system and work surfaces, including under the monitor, keyboard, printer, etc.
Vacuum vents on the computer case and all peripherals.
Remove the case cover and ground yourself by touching the metal computer chassis or, even better, wear a grounding strap. Blow out all debris from inside the case with a compressed air duster, being careful not to damage any of the wiring or electronic components. Use long cotton swabs to get into crevices. Replace case cover. Unplug your keyboard, turn it upside down and shake gently, then use a brush to clean between the keys.
