Keyboard Cleaner locks your MacBook’s entire keyboard for 30 seconds for you to wipe off stains, brush it clean, or anything else! 
All keys and hotkey combinations will be blocked - even the power button and most of the Touch Bar keys, so you can clean your computer without needing to shut it down. We hope this app be helpful in maintaining your keyboard clean daily, especially during this tough time.
