Hi Amber,
we have forwarded your request to the German specialist for cleaning art
and artefacts, Dr. Dipl.-Rest. Paul-Bernhard Eipper, and he says: "Every
object is different. So it would not even be enough to post a photo
here. But, if nothing stands in the way, I would normally say: I would
prefer a solution of Marlipal 1618/25 [now: Emuldac], 0,00025% in tap
water, 25 °C, used with care with a micorporous sponge." Never use any
household or cosmetic products (including the household or car cleaning
sponges).
I may add: Also in this case it needs a conservator keeping his/her
knowledge up to date. As the term conservator is not protected and some
restorers do not update their knowledge or cling to secret cleaning
mixtures, there are "different" approaches worldwide.
This may be usefull, too: http://www.museum-aktuell.de/download/d_90.pdf
