I'm clueless when it comes to any sort of mice modification / opening them up, can't find any videos for the Kana so thought i'd ask here...

I spilled beer over my Kana, fortunately Mouse1/2 is working perfectly still, but the scroll click is stuck and doesn't do anything, mouse 4 is working but noisy and slightly sticky...

How easy / difficult will it be to clean the mouse to get it as it was? How hard is disassembling and reassembling the Kana? Any videos or forum threads that could assist?

Trying to decide whether or not just to buy a new one and save the fucking around.
