Casio Z-750 or related disassembly help?

Does anyone have any experience disassembling a Casio Z-750 or similar
model in order to clean the sensor? I've got almost half a dozen large
black smudges showing in all photos where the aperture is small. I'm
guessing I've had some condensation issues inside the camera. Any help of
pointers would be appreciated.

 

Duh! Not very helpful. The request for info is an attempt to gauge what is
involved to determine when/if I might give it a try. The only other
alternative is to send it in to Casio, though I wonder if the cost
associated would be worth it to me. As it is my patience for dealing with
the images in post processing is wearing thin.

So here's a fixed lens, metal case camera that goes against the endless
diatribe of our resident loon Rich.

 

No offense, but I tried that from a hand can duster prior to posting. I'm
not will to try anything higher pressure than this. I'm a bit more
conservative than you and your Nikon cleaning system, even though I have
easy access to compressed N2 at pressures higher than a standard K bottle
and in much, much greater quantity.
