Acid in paper is one of the chief culprits of paper destruction. The Library of Congress in the mid-1900’s decided to initiate a mass deacidification project. They wanted a product that would neutralize acidic paper and add an alkaline reserve. The end result should give the paper a pH value between 6.8 and 10.4 and that it be evenly distributed throughout the book. The product should not cause damage to adhesives, inks, dyes or paper pliancy. The chemical had to be safe to use and be able to be used on any kind of paper. These seem like tall orders but several companies were able to answer the call. One of them produced the product that we sell which is BookKeeper Spray. The one negative comment I did see about it was that it left a residue on the paper – but we have used it here at Bags Unlimited on many types of paper products and did not find this to be true. We sell what we consider to be a safe, easy to use and effective deacidification product.
