@iuser if you want to "get rid" of it be honest and let the next person know that it had some liquid exposure. Yes, you can run into trouble down the road. That will most likely be caused by corrosion. You said you opened it up to wipe it down, which is most likely not enough. What you should have done is cleaning it. Disassemble your phone using these guides. Once it is disassembled, you do need to clean it properly. You will need high grade isopropyl alcohol and a soft brush. Use this guide to see how to clean it. Even so it was written for a 3G all the points are still pertinent to your phone. Do not forget to remove the EMI shields for proper cleaning. While you are cleaning it, check for any broken, missing or burned looking components. Or you could use an ultrasonic cleaner if you have access to one. When it is properly cleaned, replace the battery. All these steps are to avoid delayed failure caused by corrosion.
