Just posting a success story to improve morale. Macbook got completely soaked, left out in the rain. I did all the wrong things, put power on it to try and SMC. Took it apart even though I knew it would void the warranty because this has happened twice before and put me back $500 each time. Pulled the party and disconnected mag port, let dry for 2 days.
2 days later hook everything up and try to boot, nothing but a dim light.... heart broken. I then notice some corrosion on the logic board, run to the store and get some alcohol and a tooth brush. Got rid of corrosion, cleaned mag port, powered right on.
