Remove corrosion from camera without complete disassembly?

I recently got sunscreen sprayed in my camera, and now I believe the shutter button might have developed a short, which locks the camera up. Upon disassembly, I can remove the portion of the camera with selector/zoom/shutter dials, but not further disassembly can be made without some major work. Is there a way I can remove any corrosion buildup in this part without damaging it? It is not connected to any power source, so liquids are fine, but it does contain an array of plastic and metal parts, as well as ribbon cables.

I think you really would need to dismantle it. See what happens when you do: https://www.instructables.com/id/Unbelievable-camera-service/

lol :) ive gotten shocked by these things before... they hurt like heck... Took the main portion of the sunscreened things out and bathed in 91% alcohol.... Worked like a charm (after 12hrs drying...)
