So I have had this Macbook Air for about a month? I was just cleaning the screen and while pouring some screen cleaner onto my cloth I split a little bit on the keyboard... Not alot at all but there was some. Everything works fine and I don't think much got in as I wiped it up as quickly as possible (The keyboard is clean now in case you were wondering). The only thing I'm worried about is if there is some liquid damage indicator in the keyboard in case I ever had to get a repair in the future?
