Hi Terry - If you meant that my statement about trying to cause damage intentionally did not pan out in this instance, I have no problem being 'inaccurate' about that. :-). I had not tried to damage a record in the way you described and was speculating. You are to be congratulated for conducting the experiment and reporting on it! Although it is a single test, it seems to be good news.
When you say you "let it cook for more than an hour" I took that to mean you let the record simply sit in the USC subjected to constant cavitation
Was the ultrasonic frequency constant throughout? What was the frequency? And what was the water temperature? I suspect the water temperature rose as the US machine operated. Did you use only water or a solution? Can you say what machine you used?
This seems to be relevant news and adds to what we're learning about cleaning records via a US machine. I'd like to suggest you document your experiment and observations and present that here as a new post for more to see. Thanks for the follow-up.
