I inherited a rusty, crusty French frame with internal cable routing. The brake housing was frozen inside the top tube. With great difficulty I managed to pull out the wound steel wire and inner liner, but the outer plastic liner (and possibly other gunk) is stuck inside (the walls of) the internal cable sleeve in the frame.

I figure I'll seal up the holes and use top tube clamps, but I'm curious if anyone has any ideas about how I might be able to clean out the inner cable sleeve. I tried to jam a good brake housing in there and it wouldn't budge. Chemical solutions are off the table for me.
