Stubborn decade-old glue residues on test specimens: 0
Moral of the story: do not fuck with someone armed with a lab full of strong organic solvents and acids...
Ten years ago, someone in my lab prepared a bunch of long-term test specimens... without thinking about how on earth anyone would treat the things. They have been wrapped in thick aluminium tape, bolted onto racks, and glued together with the Glue That Will Not Die. I think they've bounced around from desk to desk over the last few months, with no-one prepared to touch the things.
How do you seperate flat rectangular plates glued back-to-back across their whole surface area? I ended up soaking them in toluene, as even acetone wasn't breaking down the glue fast enough. A few droplets of the solvent melted my gloves, too... it seems to be fairly effective :)
