How to Clean Mac Display Safely? To clean your Mac display safely, first shut down the Mac and unplug it from power. Use a soft, lint-free microfiber cloth to gently remove dust and fingerprints without applying heavy pressure. If needed, lightly dampen the cloth with water, but never spray liquid directly onto the screen or allow moisture to enter the ports. Avoid paper towels, abrasive materials, and strong household cleaners, as they can damage the display’s coating. For the best results, clean with gentle, circular motions and let the screen dry completely before turning your Mac back on.
