Book Cleaning @ Product Spotlight
There’s
a slow fire burning
that threatens to destroy our libraries’ irreplaceable materials. Paper-based books
and records are in danger of degradation not only because of their construction
but also from improper storage, cleaning, and treatment. While acid-, lignin-,
and sulfur-free papers have largely replaced their more fragile wood pulp–based
predecessors that were subject to cracking, yellowing, and disintegrating,
there is still a danger of acid-free materials—mostly those manufactured after
the 1990s—experiencing acid migration when they come into contact with
high-acid documents, acid inks, pollutants, or other chemicals.
Then there’s the
issue of dust. Dust that covers books and other materials gives off more than
the appearance of neglect. It absorbs moisture, increases acid hydrolysis, and
causes a quicker breakdown of valuable resources.
Preservation and
cleaning practices can greatly extend materials’ lives, along with the use of
dedusting vacuums and deacidification sprays that help neutralize the acids in
paper and create an alkaline buffer by increasing the pH of acidic paper.
Deacidification processes can use water (aqueous) or not (nonaqueous or
gas/solvent-based), depending on the materials’ construction, makeup, and type
of dyes or inks used during printing.
These five
deacidification and vacuum companies specialize in preservation of all kinds of
materials, from books and newspapers to maps and other unique documents.
