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

@ljgerens While I don't necessarily advocate for using tap water, others including Neil Antin do. I offered it as a possible remedy to rinse detergent if used in the US machine.   In my post I recommended rinsing with Distilled water after using tap water.  Since the water beads on the vinyl surface, there should be little transfer of contaminants to the record surface unless allowed to dry.  A distilled water rinse eliminates the problem, since the contaminants are clearly water soluble. Using detergent without a rinse would create a much bigger problem.  

If I remember correctly, Neil suggested that I use a final rinse consisting of a distilled water spritz (my regime included a distilled water bath). Has he changed his mind? Or are my marbles disappearing?

For context, mine was a special case, in that I had access to running purified water for a first rinse, second rinse in a distilled water bath, third rinse spritz.

@terry9 On page 43 of Neil's book, he demonstrates with pictures rinsing with tap water using the label protector handles and mentioned the distilled water rinse/spritz using nalgene bottles.  Marbles intact-at least in this context!

@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.

I don’t think that being accurate is "trying way too hard." But YMMV.

I guess things have changed a lot in 10 years - because 10 years ago it seems there were lots of misc US machines running at less than 40KHz. I’m not in a position to measure everything, so I need to take most specifications on trust. Guess I’m a little less trusting of everyone selling on EBay. Again, YMMV.
