Can't get phone to charge

Soda hot spilled in my charger cord. Don't know how long the cord was in the soda. I shook the cord out and let it sit for a little while. I plugged it in my phone. A warning message the popped up on my phone saying “ moisture has been detected in the port. Instructed me to unplug and let it dry on its on or use cool air to help dry faster". So i turned phone off. I put phone and charger cord in front of fan for like 3-4 hours. Then i turned it back on. The message had went away. I plugged it up to the charger. The message i got previously never popped up and my phone started charging. It was on 3%….well it got all the way to 80% and quit charging. Now i can't get it to charge. What should i do?
