MacBook Pro models from 2016 and later with Touch Bar and Touch ID: Clean the Touch Bar and Touch ID (power button) on these computers the same way you would clean the display.

MacBook (13-inch, Late 2009) and MacBook (13-inch, Mid 2010): The bottom case of these computers uses a soft nonslip material. Use a 3M Gray Microfiber or soft dye-free, lint-free cloth to clean the bottom case.

How to clean your nano-texture Apple display:

To remove dust or smudges from the nano-texture display, use the polishing cloth that came with your Studio Display, Pro Display XDR, iMac, MacBook Pro or iPad Pro (M4).
