With Apple’s refresh of the 27-inch iMac, a new option is available that previously was only offered on the Pro Display XDR. You can now ordet your iMac with a nano-texture display. This reduces glare to a bare minimum, but cleaning the nano-texture glass on your new iMac is quite different from other display options.

What’s the Big Deal About Nano-Texture Glass?

When you order your 27-inch iMac with nano-texture glass, Apple actually etches the coating into the display at the nanometer level. Apple claims that it “reduces glare while preserving contrast, for jaw-dropping image quality.” The texturing scatters light as it hits the display, minimizing glare and reducing the undesirable haze and sparkle of the normal matte coatings.

Apple provides a special cleaning cloth for the nano-texture glass. The company says you should never use any other material on the display or you risk damaging the glass. So, how can you clean the nano-texture glass on your new 27-inch iMac if it gets really dirty?

Cleaning the Nano-Texture Glass on Your New iMac

As it turns out, the key to removing difficult smudges is something you probably already have around the house. Take that 70-percent isopropyl alcohol (IPA) solution out of your medicine cabinet. Moisten the cleaning cloth with it, and you can easily wipe away those hard-to-remove smudges.

Once done, you should clean the polishing cloth to remove excess isopropyl alcohol. Just follow these steps:

  1. Wash the polishing cloth by hand with dish soap and water.
  2. Rinse the cloth thoroughly.
  3. Allow your polishing cloth to dry for at least 24 hours.

Should you lose the polishing cloth, or want a spare, you can order a replacement directly from Apple Support.

A dry procedure to clean with a cloth will ruin (SCRATCH) the display if it contains dust; and mostly if it contains a lot of dust. It is better to remove such dust first, with a air blower, anti-static magic duster or hoover.


That sounds better. Last week I got the impression you couldn’t even use ISO on it, just the cloth.
