I wonder what happened to user @inna? (He was a frequent poster here for a while). What does this have to do with your question? He sent me a somewhat noisy record he had a couple copies of, and was curious to know whether my cleaning methods would produce a better result. (I combine conventional vacuum cleaning with ultrasonic, using a point nozzle type vacuum machine- typically more expensive than a wand type). if @Inna is still around, he can comment for himself- my recollection, not surprising to me, is that he heard more information from the record, but it didn’t necessarily eliminate the noise.
FWIW, I have been able to reduce groove noise type distortion on some copies that I would have attributed to damage of the record, but it usually involves multiple cleanings, using something like AIVS No. 15, pure water rinsing, and ultrasonic --sometimes repeatedly. (And in some cases, the record IS damaged, and no amount of cleaning will help). This is almost always something that involves an older record that was not handled or played with audiophile care, circa the late ’60s or early ’70s.
There’s a ton of stuff here and elsewhere on the benefits of ultrasonic. I like it, but it is not the sole method I use for cleaning- and I find, as I’ve written at length (sorry, I don’t mean that to sound pompous- just people might get bored seeing me say the same thing repeatedly), that the different cleaning methods- manual cleaning fluid application and vacuum RCM plus ultrasonic --are complementary and synergistic in result.
