I accidentally spilled some tea over my MacBook Air, the computer itself works but the keyboard feels sticky when I press it down.
Wait! You don’t want to use hand sanitizer because that will get stuck under the keys & will attract dirt/grime! Instead, get a toothbrush and >90% Isopropyl Alcohol, dip the brush in the alcohol and scrub the keys gently to remove the dirt/grime. Wipe with a microfiber cloth when done.
Use some alcohol, it usually works good for me.
