Got my hands on one of these the other day. Sony HitBit HB-75
Unfortunately, the keyboard has had a 'liquid upgrade' at some point so 15% of they keys do not work.

what's the best way to clean the internal contacts of the keys. I have to remove them one by one from the keyboard PCB as you cant remove the top of the keys without access to both sides.

Isopropanol alcohol? Perhaps combined with compressed air if there is a mechanism that needs cleaning.
