KS, rice and/or oatmeal will never fix your phone. None of those will prevent corrosion or a short circuit. Any of those "tricks" are the equivalent of doing nothing. Once your device has received any water damage, the only way to work on it is by cleaning it properly. Do not charge, sync, or try to turn on a water damaged device. That can make a bad situation worse.
Start off by disassembling your Note. Use these guides for that. To properly clean it take a look at this guide. It was written for an iPhone 3G but all the points are still pertinent to your phone as well. While you are cleaning it, check the logic board for any missing or damaged components. You must remove any EMI shield to ensure proper cleaning. Once that is done, replace the battery and reassemble the Note. Only than can you do a proper trouble shooting. If you have access to an ultrasonic cleaning, than of course go that route. Water damage is the toughest to diagnose and the hardest to repair, since virtually any part can have failed.
