Why does my controller keep looking down? -water damage (only r3)

i spilled water on my controller while playing and tried to dry it but i think i was too late. Now my right analog stick keeps looking down and i literally can’t look up . I tried to dry it with a hairdryer it worked for 3 minutes and then it didn’t anymore. After that i opened my controller and used the hairdryer at the right analog stick but it was even worse. Does anyone know how to solve this problem because i can’t find a solution and don’t have alcohol. And it’s been a day so it is dry it’s just the right analog stick right now.
