If the previous owner played a dirty album they literally ground the grunge into the bottom of the groove area and there it remains impacted into the vinyl.Ultrasonic will not remove this material. It has a physical bond to the vinyl that is not broken by ultrasonic action.
Ultrasonic will remove the light dirt, but unless you utilize vinyl cleaning agents in the bath you will not remove the oxidation that builds up on vinyl over time.
I have tried ultrasonic and I have tried pressurized water jets. These still do not dislodge the impacted debris.
Luckily, I have found some wonderful 1 mm upholstery velvet that provides gentle scrubbing action to removes a great deal of the impacted debris. It is not perfect. Some albums are still noisy but are playable.
Mechnical scrubbing action is a more successful way to break the impacted material loose as well as remove the surface oxidation from the vinyl substraight.
