I have a piece of cotton cloth that has been attached to a cardboard backing with mucilage adhesive. The glue is extremely old and crusty and was apparently very heavily applied. I need suggestions on safe removal. I doubt water will touch the dried glue. Are there any solvents that might be safe or should I try a dry removal? ========================================================= Important Subscriber Information: The Museum-L FAQ file is located at http://www.finalchapter.com/museum-l-faq/ .
