Hi, I spilled approximately 50ml of beer on my Air's keyboard yesterday. I immediately put it on the side and started wiping the remaining liquid off with a tissue. The notebook works just fine. Around 10 keys got a bit soft and there's the slight smell of beer... Is lifting the keycaps and cleaning the buttons with an alcohol-based cleaning kit gonna help? I am afraid one day it will just stop working. Any other preventive measures? Thanks!
