First of all, you made two huge mistakes: Never try to dry a water-damaged phone with a hairdryer, and don't try to charge it or turn in on. While drying it with your hairdryer you force the water to spread out all over the logic board, causing more damage then it does good. You can try to give the logic board a good clean. Just like oldturkey03 said. I personally have good experience with http://irevivespray.com/. Good luck!
