Thumbs up for ultrasonic record cleaning

They explain the 120kHz on their web site.

As I remember, it's something about the 120kHz making the process more amenable to using simple water and keeping it the right temperature.  They use more power than other machines to approach the cleaning action of the lower frequency machines. 

The higher the frequency, the smaller the bubbles, hence the better to clean small spaces and crevasses.

One of our big problems with vinyl is grease (fingerprints, etc.). It's hard to see plain water being very effective at removing that, irrespective of frequency. I use a lab grade detergent (Versaclean from Fisher Scientific) for surfactant, and  chemistry at 45C.

But this requires a rinse or three.

Michael Fremer reinterviewed Mr. Kirmuss at the Munich show. A lot to think about after hearing the interview.  https://www.analogplanet.com/content/if-charles-kirmusss-record-cleaning-machine-and-regimen-correct...  

Well, I put my money where my laziness is...and ordered the upcoming Degritter Ultrasonic RCM!

Interacting with the folks at Degritter (as well as reading beta user reports) has given me confidence in their product and in their character, so it seems like worthwhile gamble. If it works as advertised it would be the perfect record cleaner for me.

It’s supposed to ship in September. Whenever it arrives, I’ll let people know my impressions.

More info here, with some demos:

FYI: Just a couple days left to get in on the first batch. 

I have a KLaudio and a Loricraft
i have never heard any issues with sonic degradation

I have cleaned a large amount of my rare collection of records. They only sound more refined with enhanced sonics


only better resolved low level resolution, removed tics pops static noise floor, separation of instruments etc

as for the ’hypothetical’ issue
Klaudio did extensive 9 hour continuous tests with yellow vinyl and found no traces of vinyl shavings

I have had the KL since 2013
it has been incredibly reliable
The machine was heavily researched, patented ultrasonic array, etc. F

I don’t find a salesman in a white coat to dismiss a viable urc Using fear of 'improper' variables to sell his wares. Especially when some of his comments are the opposite of physics

hopefully he sells a great urc at a good price
