Subject: Copper sulfate
**** Moderator's comments: This query comes from a person who is not on the DistList and will not see any responses that are posted here. Please respond directly to sender and if of general interest post it here as well We have located a jug of "Mildew Treatment" prepared by a previous employee which contains 2.5% CuSo4. The hand typed instructions say to apply with a cloth which has been dipped in the solution and dried prior to use to wipe mildew from a book. We quickly checked Mary Lynn Ritzenthaler's _Preserving Archives and Manuscripts_ but saw no info about Copper Sulfate. We have numerous periodicals (bound in buckram) and leather-bound books which have been stored in a damp, dirty basement for *too* many years. Has anyone used CuSo4? If so, please advise. If not, recommendations are welcome. We are a small staff without a preservation department or much time to allot to this project. We need "quick and dirty" solutions for a "damp and dirty problem."
