@aoshahh the first thing I suggest is that you no longer try to do anything with the phone until it is cleaned, you are running risk of further damaging it. Disassemble the phone using [[Topic:iPhone 4S#guideList|these guides.]] Then clean the phone with +90% isopropyl alcohol. Use [guide|5825|this guide] to clean it. Make sure to clean all the connectors and cable ends. After you have everything properly cleaned, '''replace the battery''' Reassemble your phone and re-evaluate. If you do not clean your phone, you will continue with the corrosion failure and your phone will be a lost cause.
