Committed to the Original

The Bookkeeper® Deacidification Process neutralizes harmful acids and greatly extends the lifespan of books and documents. Accelerating aging tests have demonstrated that paper treated with Bookkeeper will have a life expectancy of a minimum of three to five times longer than that which has not been treated.

Bookkeeper is available as a deacidification process or in the Spray System and Spray Products.
