Dust cloths

My references were to tests during the 80's. The LC and NARA info
was picked up at conferences.  In print there is the following:

from American Archivist, v.46, #4, p. 473:

    Dust Cloths Tested.  Michele V. Cloonan has recently been
    involved in the testing to two dust cloths:  Chicopee's Stretch
    'N Dust and Guardsman Chemicals' One-Wipe.  Informal testing was
    begun during the cleaning of the Newberry Library's collections
    in 1982.  Laboratory testing of these cloths, however, was not
    possible until Winter of 1983. These tests, carried out by
    Walter C. McCrone Associates, were designed to demonstrate
    whether or not the two dust cloths left harmful residues on
    leather, paper, or book cloth that would contribute to the early
    deterioration of library materials. Similar tests had been
    executed by McCrone on other cleaning products for the Library
    Technology Program of the American Library Association in the
    late 1960s.  The most recent test made use of microscopic
    examination, phloroglucinol tests, pH determination, color
    change, the Elmendorf tear test, and the M.I.T. folding
    endurance test.

    The test results indicated that there was no significant
    difference between the samples treated with a dust cloth and
    those that were not treated with any cloth.  Therefore, both
    Stretch 'N Dust and One-Wipe can be safely recommended to
    librarians who need to clean their collections.

    The Newberry Library provided the leather and paper samples, and
    Bill Minter the cloth Samples.  A more detailed analysis of the
    testing will appear in an upcoming issue of "The Abbey
    Newsletter:  Bookbinding and Conservation."
