Thumbs up for ultrasonic record cleaning


My Cleaner Vinyl ultrasonic record cleaner arrived today and it’s impressive.

Everything I’d read indicated that ultrasonic was the way to go, and now I count myself among the believers. Everything is better - records are quieter, less ticks and pops, more detail etc.

All my records had been previously cleaned with a vacuum record cleaner and were well cared for. Nonetheless, the difference is obvious and overwhelmingly positive.

@Labpro–– Although much of this thread is devoted to DIY methods, many of us have had the Audio Desk. I owned one before the "Pro" was introduced, and based on the recommendation of some early adopters, reduced the amount of "fluid" I put into the bath- not so much for cost-savings but to reduce the potential for fluid residue. Honestly, I could not hear artifacts from the cleaning on the original AD, at least when using just a capful, rather than a whole bottle of the fluid. (Robert Stein, the importer, may disagree, but he’s not a disagreeable person).
I have shared some records with a collector friend who has the "Pro" version, he loves it, and the records sound fine when played on my system, many states away from him. In a couple instances, I have done more intensive cleanings for him, but no rigorous comparisons of before and after. My take is that you should be satisfied with the performance of the AD, and there is some benefit to the ’no work’ approach.
There were some (ahem) issues with the early AD machines and most of us moved on. I bought the KL before AD introduced the "Pro" model, but the KL doesn’t allow for a surfactant. So, it’s trade-offs. Much of the attention on DIY is cost savings over the commercial US record cleaners, but some is getting better results than what those provide through a medical/lab grade US system, the use of surfactant, control of temp, frequency, de-gassing, filtration and other features or variables that you cannot control on the ready made for LP cleaning units.
My main issue with the AD when I owned it wasn’t the residue of the fluid, but that it didn’t do as good a job on problem records- I buy a lot of used, rare vinyl, some of it in less than pristine condition (not beat up copies, but ones that benefit from more intensive cleaning, combining manual cleaning, point nozzle vacuum and ultrasonic). Others may have a different view, but assuming you are dealing with new records or older records that were well maintained by audiophile types, you should not have any issues over cleaning quality.
Hi Whart,
Thank you for the thoughtful and thorough feedback.

I like your idea of starting of with less fluid, then experimenting from there.

Also, I'll probably keep my Clearaudio Smart Matrix Pro cleaner, to address the tough-to-clean records.
Thanks again,
Labpro
For those following all the different "opinions" on 
what frequency works best etc I came across this site
from another forum.
Which shows in real world usage that
as ultrasonic frequency increases bubble size increases.
And as frequency decreases intensity/force increases.

Higher frequency may in fact not be the best after all.

@totem395 - Tomtem- i think you misstated the article which (correctly as I understand it) says that higher frequency = smaller bubbles. The theory, so far as record cleaning goes, is those smaller bubbles may do more to get into the grooves. But they are less powerful than the larger bubbles generated by lower frequencies when they implode.
I think the folks on the DIY Audio site have experimented to some degree with cleaning effectiveness of different frequencies. I like the idea of having a machine that provides alternate frequencies. It is a good article in talking about frequency and power. Thanks!

The VERY interesting Degritter brand Ultrasonic cleaner is scheduled to become available in January 2019, at what retail price I don’t know (last I heard, a little over $2,000). It operates at 120kHz, for reasons explained on the company’s website.

Whart is correct; the higher the frequency, the smaller the size of the bubbles, and the less powerful (put another way, the more gentle).
