Rebuilding the Relay Board, Question about epoxy removal... Options

[RoadGlue]

Hope you're all having a good weekend! I'm currently rebuilding my relay board (and the rest of the teener!) and have managed to scrape/chip off most of the epoxy from the bottom side of the relay board. Geez, that stuff is like soft obsidian! I've heard that there are certain chemicals that will safely dissolve the epoxy without damaging the board, but couldn't find any information by searching through the archives. Anybody care to share their tricks?

I'd have Teknon supply me with one of his rebuilt boards, but I'm a do-it-myself and learn-it sorta nut. Plus I love soldering. :)

Thanks!

Actually, I removed mine with no solvent. All that was necessary was
some dental picks and a small screwdriver. Its kind of a pain but
with some picks it scraped off pretty easily in a hour or so.
I'm not sure if it helped but I did mine in the
winter in the garage when the temp was in the 40s and the
stuff crumbled away pretty easily. You may want to toss it in the
refrigerator or freezer for a bit.
Given how easy it was without solvent, I'm not sure I'd want
to go that route until most of it was gone. Seems like you'd end up
with a goeey sticky mess that is more work than just scraping it off.

Also, to try your solvents, scrape off a small piece and put it into
the solvent to see if works. I never found a solvent that worked
and eventually gave up and started scraping, which turned out
to be the way to go.

(I've got pics if you want to see it)
