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

Good morning-

I've recently acquired for collections a very large painted wooden sign that was installed for 60 years in a local bar. The sign, and the bar, are legendary.

The sign was painted by hand, and while it was sealed originally, decades of light, smoke, and environment have created a layer of what I am calling "bar deposits."

Any ideas about a gentle cleaning? I'm concerned about the use of liquids, as only the top surface was painted or sealed. I'm not trying to restore it to its original, just to clean the top layer a bit, and prevent further damage by these ethnographic deposits.

Thanks
