Isaac, two things that will make this a very difficult repair. Number 1 is '''rice'''. It absolutely does nothing for you. It only delays repair and will increase the chance of corrosion. Number 2 is that you waited a year. This will further increase corrosion damage. You can try and clean it. Use [guide|5825|this guide] to see how to clean it. It was written for an iPhone 3G but all the points still pertain to your iPod as well. [http://www.ifixit.com/Device/iPod_Touch_3rd_Generation#guideList|Here are] the guides to work on your iPod. After you have it properly cleaned, '''replace the battery''' and reevaluate. Water damage is the hardest to diagnose and the most difficult to repair. Hope this helps, good luck.
