My old mans next door neighbour used to own a bike shop and says he swears by putting diesel in there.
Leave it for a few days upside down and says he has always managed to get them out this way.
Haven't tried it yet so cant confirm if it works or not.
My frame is a coppi with neuron tubing and campag chorus aero seatpost both mint so really don't want to cut it out or use caustic etc want to save it if I can
