This was used by a number of archives, including LOC, until the freon issue arose. They were then closed down.
You might check the article to see what solution they are using and, perhaps, share that info with the rest of usn's.

I see in the latest edition of Playback (the bulletin of the British Library Sound Archive) the mention of an ultrasonic bath for disc cleaning.
I have never heard of such a thing; though it might be safe for vinyl, it seems to me that such a process would wreak havoc on a vintage recording. And even on a vinyl record you have a label to worry about.
Does anyone know how this is used at the Archive?
