Without typing gibberish or breaking anything
Before you wipe anything, open SeventyClean and click Lock to clean. The keyboard, trackpad and mouse are blocked and the screen goes black, so you can clean without opening an app, selecting everything or deleting a file by mistake. To unlock, hold both Command keys for 3 seconds.
Download the free SeventyClean trial (7 days, macOS 13+).
A dry microfiber cloth handles dust and fingerprints. Wipe gently over the keys and the palm rest.
Lightly dampen the cloth with water or isopropyl alcohol at 70 percent max. Never spray anything directly on the keyboard. Wring it out well: damp, not wet.
A can of compressed air, held upright and close, clears crumbs. Tilt the Mac so the dust falls outward.
Get SeventyClean and clean stress-free, for life.
