I recently bought a big plastic tote full of 80 spring clamps for $20! Great deal at only .25 each plus the handy storage tote included in the price. The only problem is that many of the clamps have polyurethane glue hardened onto the jaws. The rubber jaw covers are long gone, which isn't an issue for me, but the glue makes it difficult to get even clamping pressure and in some cases makes the clamps twist a bit due to the uneven build up of the glue. Other than that, they work great. The springs are strong etc. So my question is, is there something I can use to get the glue off of the clamps? I could sit there and scrape each one clean one by one, but that would be a pain. Do you think soaking them in thinner, or some other solvent, would soften the glue enough to dissolve it away? I could just try different things, but whatever I try, I will have to purchase, so instead of buying a bunch of different things to experiment with, I thought I would turn to the expertise of all of you. All suggestions welcome and greatly appreciated.
Thanks in advance!
