Camera that went Swimming

I went swimming with the camera in my pocket. Ok, I feel in a ditch and went under. The camera still works, well it tries to work. the lens wants to come out but doesn't quite make it. I have the camera apart, but wanted to know if anyone knows how to get to the extender for the lens. I think it's just dirty and wants to be clean. Deep cleaning is what I need to do.

I have the casing off the LCD disconnected and it doesn't look to bad.

do I remove the lens by going in the back or is there a clip in the front that I can't see?

Your right the name of the rapair shop is Garbage can. I took it apart and holy ta lido lots of parts. I had the camera for a long time and I take a lot of photos(my hobby). It has been in the shop a couple of times and they fixed it with no payment. This time with the mud and all not worth it.

Thanks for the response.
