I agree with Duane that we are beyond the use of household chemicals for
cleaning discs. Every time I see the topic of cleaning discs raised on
ARSClist, I am reminded that as archivists, when we clean discs, we are
performing conservation treatments, regardless of our training. According
to article VI of the "Code of Ethics of the American Institute for
Conservation of Historic and Artistic Works"

"The conservation professional must strive to select methods and materials
that, to the best of current knowledge, do not adversely affect cultural
property or its future examination, scientific investigation, treatment, or

We should abide by these principles, even (especially) if we aren't
conservators. I would argue that archivists have the same responsibility
not to use household chemicals without having them tested first. With all
due respect to collectors (who have rescued many recordings when the
archival profession wasn't paying attention) household dishwashing
detergent is not an acceptable way to clean recordings, especially when
there are other, better options. Dawn and Ivory liquid probably contain
harmless ingredients, but without assurances and testing, we shouldn't use

I can't speak for Duane's products, but any manufacturer that sells
products to the archival community should provide full disclosure on what
active and inactive ingredients are in the product and what testing has
been done to ensure that these products will "not adversely affect cultural

As I have pointed out on this list before, the Library of Congress has
created a recipe for a wonderful cleaning product that has been tested by
their conservation scientists:
Some archival supply firm should make this and sell it, since the main
ingredient is difficult to obtain in small quantities.
