Yaa I’m aware of the threat of moisture to cardboard. Again, I’m not recommending a particular treatment for these discs. Rather, I work alongside paper conservators, we’ve employed their expertise on paper and adhesives where relevant, and with additional information (composition of the disc would indeed be crucial), I’d be happy to consult!

Simple light application of distilled water with a dampened pad removed it easily. It was the least of our problems as 24,000 78s arrived badly packed, 8,000 broken. For every near mint Bessie Smith found (8) there were 10 Blues and R+B trashed. Bye Bye the Jimmy Witherspoon's. Hurts so bad… b.george

Rather, my paper lab colleagues have been able to offer their expertise on a few audio projects where papers and adhesives have been involved, so curious what others have encountered! If you’re able to learn more about the disc, paper and adhesive formulations I’d be happy to consult with them. Good luck!

The caveat (first) is that there are different types of adhesives, some are water soluble some are not, which is what Bryce is getting at I am guessing. In our case we have used the process to remove lacquer disc labels affixed with water soluble adhesive that feature non-water soluble ink when the label covers grooves. There is a gore text sheet that can be trimmed and damp blotter paper against the gore-tex. It is similar to the damp blotter pack on this page: https://www.conservation-wiki.com/wiki/PMG_Humidification,_Drying_and_Flattening. We used reverse osmosis water. One can also use mylar sheet trimmed/with cut outs, over the gore-text (or under) to targer specific areas. There are some different concerns than when applying it to disc as opposed to photographs, but the cons section is relevant, including the one:

Too little water in the system and the photograph needs long periods of time that may be detrimental to it. Too much water in the system and the photograph can become too saturated or wet with water, beyond dampness."

>>>>> IMHO, It may not be worth the time required, unless there is something particularly unique or special about the disc. But it may be an opportunity to test process. We developed/used it for laquer and very rare discs that were in good shape and featured no cracking. Even with water soluble adhesive it may need to set for several hours to possibly overnight (in our experience).
