If you can get hold of it from somewhere..

Prepsol  manufactured by Dupont.

It was originally marketted  as a marine preparation solvent cleaner.
It's not as strong or aggressive as thinners, doesn't evaporate like petrol or meths, but it's stronger than white spirit.  It doesn't take the paint off like T Cut.
Soak a rag, wipe it onto glue, let it sit on it for 5 or 10 minutes, then just used the same rag to wipe it slowly off.  It will dissolve the glue.

If you can find someone who sells it, that is the stuff.
