How do I fix my nokia xpress music 5320, it fell in vine?

My mobile phone nokia xpress music 5320 model fell into a glass of vine, when I removed it from the glass it worked for some 10 seconds more and then it turned off on its own. Afterwards I blow-dried it and a couple of hours later it turned on. And ultimately it went off again. The battery works and the sim and memory cards do as well.
Does anybody have an idea how to fix my problem!?
