Try wiping the screen down with just the microfiber first. Computer repair technician Jeremy Mercer says: "Most of the time, you can clean the screen with just a dry microfiber cloth, because it's mostly going to just be fingerprints and things like that. If you do need more cleaning power, like if there's been a liquid spill or something greasy on the screen, use 91% rubbing alcohol or an electronics-approved screen cleaner like Screen Mom."
Method 2 of 2:
Using the Right Materials
Avoid using cleaners with acetone and ammonia. Cleaners that contain acetone and ammonia are too harsh for an iMac screen. Also avoid using regular household cleaners to clean your iMac screen, including window and glass cleaners.[6]

Don't use window cleaner or other harsh chemicals to clean your phone. Computer repair technician Jeremy Mercer says: "Household cleaners will de-laminate most Apple screes, especially in the retina era, or anything from late 2012 to mid-2015. When that happens, you'll start to see gray spots on the screen that won't come off."
Avoid using paper towels to wipe your iMac's screen. Paper towels, toilet paper, dishcloths, and tissue paper are too abrasive for iMac screens. You may scratch your iMac's screen if you use these. Instead, use a microfiber cloth, or the cloth that came with your iMac to clean it.[8]
