Thanks all! It seems I have three options: heat, cold or chemicals.
With cold you then need concussion to break the bond: it seems to me that there is a risk the extensions will become brittle and break.
Heat would involve the purchase of a hot air gun (and a long extension lead).
Acetone seems like my best bet at the moment as a) I have some and b) I can rig up some kind of stand and leave it on the fire escape.
Acetone won't work. MEK (Methyl Ethyl Ketone) might, provided you keep it warm and leave the parts submerged for a long, long time. It's really, really pongy stuff though. Worse than acetone, by many orders of magnitude.
