Kirmuss 'In the Groove' Ultrasonic Record Restorer - Upscale Audio Edition

I would avoid the kind of thing you see on Amazon for $160; these are made for cleaning jewelry and other assorted items, and I wouldn’t expect them to last very long; I’d stick with one that is made only for cleaning records.

@larsman You aren’t making any logical sense here. There’s no difference between the way US machines operate. Transducers create bubbles, the bubbles clean. That’s it. The only difference is in the frequency used, and many jewelry cleaners use the same frequency as the majority of $4000 cleaners.

Records can easily be cleaned in a commercial jewelry cleaner and jewelry can easily be cleaned in a Degritter. It’s all the same. You’re paying for cosmetics and, I don’t know, prestige?

I did a lot of research before getting into US and bought a $180 machine on Amazon, added a Vinyl Stack (rip) and it has worked flawlessly for six years. The entire setup cost under $400.

@larsman If the DeGritter isn't an US machine then why is it repeatedly described as such on the DeGritter website?

@terry9 What did I say that's misleading?

@larsman US is a common abbreviation for ultrasonic, bud. It has been used many times in this very thread. 

@terry9 You're trying way too hard and, like many people in this hobby, you're way too deep in the weeds.

I wasn't giving a Ted Talk on US machines. I was specifically responding to an assertion by @larsman that US machines made to clean jewelry are somehow unfit for cleaning records, which is absolutely ridiculous. In response to his assertion, I stated that all ultrasonic machines clean via cavitation and there's no reason that a machine made for jewelry can't clean an LP. I kept it simple because @larsman seemed to be having trouble with basic facts.

But yes, the kinds of machines that he was disparaging are the same machines that US enthusiasts have been using for many years specifically because they meet the criteria espoused by Neil and others. They have sufficient power to clean at 40kHz. They do the job they are designed to do, which is clean. They were recommended when I got interested in US cleaning and they're still being recommended. 

As far as QC, I very, very clearly said that I've used the same unit for six years with no issues. What more do you need? Video of it operating for the entire six years? Sorry, bud, but I didn't have the foresight.
