Center button lags, needs heavy push, AND 'Charging' when NOT CONNECTED!

Question

Ok so I was gonna sell my Nano 1st gen 2gb white so I started washing it. I kinda forgot it was electronic so I just splashed water on it. It went on the screen, and onto the click wheel i'm pretty sure. Then I used soap and washed the click wheel, and it probably went through the cracks on the wheel.
Next, I turn it on, and I have to press down hard on the middle button, not lightly as before. Probably some connection thing. So I turn it off, about to open it. However, then the 'charging' comes on, and when it's on then the battery charging icon appeared, and it WASNT PLUGGED IN. I drained the battery for a few hours, plugged it in (the computer recognised it this time) and restored it from itunes. now the charge icon was gone and it turned off properly, however the click wheel was laggy and needed hard pressing. all the other buttons and the scroll wheel wo rk fine.
so i opened it up and i don't know what to do to the wheel to get the middle button to work properly. I have unscrewed it, but do I need to detach the click wheel from the ic?
Your help much appreciated. I think it is just a connection problem with the wheel but I do not know how to fix it. Might I just dry it for a few days? Happened yesterday.
P.S. two years old so don't worry about the warranty I have opened it up before cause I left it in the washer just to dry.

Wow, I have exactly the same issue, 'Charging' when NOT CONNECTED!Its really annoying, I use it for my Nike+, its going to disrupt my training, and I'm on holiday next week. So far it just stays on until it is completely discharged, so all I do is keep it on charge all the time.
It happened after a particularly sweaty training session, so I think it must be a similar moisture problem. I've put it in the airing cupboard to dry out now, and see if that fixes it.
Did yours dry out?
