Put some of that Emeraud De Chivor in my TWSBI last night, it's so gummed up I can't even empty the ink out. Any tips

Got it soaking in a glass of water right now, but it's so gummed up I can barely turn the piston to push out the ink or suck up any water to help break it down and clean it out.

I could use some tips, haven't had to deal with this yet.
