Record Cleaning Machine ~ Ultrasonic vs. Rest

As title suggests, those of you who have switched to Ultrasonic RCM, did you find records that were previously suffered from dust and grime or noise now spins clean as whistle.

I am currently using a Pro-Ject VC-S2 with their recommended cleaning solution to clean my records which requires some efforts on my part. I don’t mind the process but still can’t get some of the records to play cleanly. Does this mean, user error or some records are just inherently noisy and buying an Ultrasonic machine like Degritter Mark II or KL Audio won’t make them play any quieter.

Did you find a process that works well for those stubborn noisy records. I don’t mind assuming the role of a pro dishwasher for handful of records..LOL!

At the end of the day, I am looking for this process to be fully automated thus my desire to consider an Ultrasonic machine that does it all.
