Not wanting to start a flame war here but: Because I do work for museums
and other institutions, I cannot use anything that has unknown
consequences. Any chemical that evaporates will leave behind a film or,
at least, a measurable amount of residue. This can be a big No-No for
archivists. The chemicals & procedures that I use for the cleaning of
media have to be cleared by the institution that I am doing the work for.
