Fingernail polish remover works great! The 100% acetone is the best if you can find it - the non-acetone stuff is actually ethyl acetate and doesn't work too well. Acetone is pretty volitile so it will evaporate and you will have no problem regluing things. I've never used debonder, but I have studied the chemistry of CN glues quite a bit - acetone is the way to go (unless you can get your hands on some methylene chloride - I'm a chemist!)
