How to Clean Your Computer Safely

To safely clean your computer, prioritize preventing static electricity damage. Power down and unplug everything. Open the case (desktop only) in a well-ventilated area. Use compressed air to blow out dust from vents and components, avoiding the fans themselves. For the exterior, a damp microfiber cloth, with just water, tackles dust and fingerprints on the case and screen. Never use harsh chemicals or abrasive cloths. Let everything dry completely before reassembling or powering on your computer.
