Solvents for agents or neutralizing media known in and of them- selves for efficient, environmentally safe mass deacidification of books and other paper products, in the form of methylsiloxanes having at least two and maximally four silicon atoms, are a replacement for the previously used, environmentally unfavorable solvents such as chlorofluorohydrocar- bons, whereby these special organosiloxanes are suitable to the same degree for use as solvents as well as for application in the recommended, efficient process and cause as little damage as possible to the books.
