First of all, I don't work for the Library of Congress so I wasn't aware of
any conflicts that you have with their preservation lab. Second, I wasn't
criticizing your products, only pointing out that all products, whether
made by a commercial company or developed in a conservation lab needs to be
evaluated by a chemist to ensure that they "do no harm." I welcome any
product that meets this standard that helps us do our jobs better.
And yes, I do wait for somebody else's approval on conservation treatments
for recordings because I am neither a chemist nor a conservator. I can't
tell a potential donor that we clean our discs with Ivory liquid. They
would understandably have a hard time taking our program very seriously if
