Well, I figured I would chime in with my findings.
1st, heart gun and scraper, works, though it kind of just smears the glue off.
2nd, and what I did, was a pot of water and about 10 % vinegar. Put the clamps in, and boil away for a few minutes, take a clamp out, and then scrape with a scraper, or just use a paper towel. The glue just comes off.
I don't know if the vinegar is truly necessary or not, but I figured it would not hurt.
Thank you
Andrew
