Yes, I am the lone idiot that glued up a bunch of cutting boards without waxing my clamps first. They were brand new clamps, I was just too excited to make some boards I guess. Now the clamp bars are covered in dried PVA glue. Is there a good way to dissolve the glue without having to scrape it off? By the way i have tried to scrape the glue off and it looks like it is going to be about a ten hour job to get it done. Just looking for a lazy solution to this. I have about 45 glue covered parallel clamps. PLEASE HELP!!

Brass wire wheel brush in a drill. A bit of heat from a heat gun or hair dryer speeds up the process.

I wonder if I can stick them in the oven first.

I wouldn’t stick them in the oven. The bars would probably be ok, not the handles or heads possibly.

After you get the glue off, try a piece of masking tape on each bar before using glue the next time. I like it better than wax.

What about using a hot heat gun and just a hard plastic or metal scraper since PVA is a thermoplastic – meaning that it melts. You could also just blast it off with a propane torch. I can’t see the torch causing any damage to the thick bar of a parallel clamp because the glue would certainly melt at around 400 degree max and the bar will not have any metallurgical changes until at least 700. I also have lots of dried glue on my clamps (although I did wax them sometime in recent memory) and think that I may go out and try to clean them up right now.

Nearly all of my old pipe clamps have scrape marks from the putty knives removing glue until I discovered that
masking tape was not all that expensive and it pulls off real easy.

Hot vinegar softens PVA glues and causes them to peel away from the surface. I’ve actually used it once to reverse a glue up gone bad. I just put a little white vinegar into a cup then microwave it until it’s nice and hot.
