Hello Shelby,
Your project for removing accession numbers from objects is indeed a challenge. It entails at least two instances of "it depends" for each item. From one point of view, it could become a conservation treatment for every procedure to avoid harming the object, assuming that the number can be removed. In the best scenario, easily-removable materials were applied to stable and impermeable surfaces -- one can only hope. Other scenarios might well include resistant materials applied to delicate substrates. it is easy to envision the damage: abrasion, tidelines and staining on paper; damage to clear finishes or paint on organic materials; rips and tears of textiles; ad nauseam.
I suppose that one could take the attitude that the objects in question are not (or soon won't be) permanent collections, so, how careful do you need to be when removing old numbers? I am not recommending free reign with scrapers, strong solvents or other aggressive treatments, mind you. Alternatives to complete removal of the accession numbers might include removal of the covering layer (if any) and the number itself, if the base layer (if any) cannot be removed safely. I suppose that obscuring the number with new opaque layers of something is an alternative. Sometimes museum staff even send an object out of the collection with the accession number intact, thinking, "Does it really matter?" I don't have a good answer to that, assuming that the applied number is very resistant to removal.
In my own experience, deaccessioned items were sent out the door with our accession numbers only partially removed, or merely obliterated. We balked at the thought of removing patina, surface coatings, or any bits of original materials by mistake. I doubt that we ever sent away any object with a complete accession number on it, but I wonder what the consequences might be if we did. Perhaps other folks on the listserv have better answers about that.
In any case, there are seldom any easy answers, and I apologize for taking so long to express that. Good luck in this project!
Best,

Subject: Object ID Removal
Hi All,
My museum just implemented a new Collections Policy that is leading to a redefining of our collection. We are in the process of some mass deaccessioning of items that simply don't relate to our story. These items have been marked with our object ID number, and I am looking for advice on how to remove that number without causing harm to the objects. Do any of you have any experience with this that would be able to share insights with me or know of any resources I can look into?
Thanks!
Shelby
