I think it would help to have a photo with arrows showing where the clips are and which way to pry to release them.

Would anyone have an idea why would 4 keys on the same printed circuit line [F1 1 2 T] fail to recover after cleaning/drying spilled wine? Membrane was supposed to prevent liquid from going further but it didn't. No visible damages to the circuit. The fn keys (on the same line as these 4) appear to be functional, except that pressing them alone (without an F-key) lights up current connection indicator [1 - 2 - 3]. Don' know if that's normal behavior on a virgin KBD.
The circuit under the membrane is multi-layered, maybe the wine got in between the layers.
How do you suggest what to use to thoroughly clean the membrane parts of the keyboard?
Can they be washed in warm soapy (like dawn) water and dried with warm hair dryer?
Warm soapy water works well to clean the membranes. Do pay attention to the temperature of the membrane, as it can get very hot to the touch easily.

The Logitech K850 keyboard is quite complex, though it is somewhat easy to fix. However, with a ton of fragile components that need to be pried on, repairs can be difficult.

How do I fix the incredibly tiny plastic piece where the foot/stand fits into? Are the side wholes enough to get two new feet without having to worry about that plastic part or does it need ot hook into that?
?
It is difficult for key plucker to remove keys from.mk850 . Is there a easy way to remove keys from it?
