Epoxy does have a solvent, but it'll eat the host too. Heat is impractical due to the threat of damaging the optics but doable. depending on how much is there, taking care to scrape it off is usually the only real option. most of the PGLs I do I just scrape it off without damaging the threads. There's a trick to it that's hard to describe but often its shear strength is less than its tensile strength so you can chip it then 'push' it out of grooves and holes if you're clever.
