It's extremely tough once cured, or if left to dry a few hours. Normal
solvents (acetone) will not cut it, but printer cleaner with ammonia in it
does get rid of most of it. Mechanically remove the rest (abrasive
scrubbing).

That would be a lot of work, and i don't see what you'd gain from it? The
printer electronics work just fine as they are.

Remember they put through a non-trivial amount of data, and timing is
critical as anything, it would not be as easy to control as a CNC machine
by far.
