@maximc clean it ASAP with 95%+ isopropyl if you don't have an ultrasonic cleaner, don't leave it to dry; the liquid is still going to be on the logic board, and corrosion will occur gradually when it is next turned on. Leaving it to dry, air out or putting it in rice does not do anything to clean the liquid inside the MacBook.
Don't know what you're talking about @oldturkey03, we use hairdryers when doing logic board repairs all the time. Feel sorry for all the fools who pay for an expensive hot air station ;)
