Degritter brand ultrasonic record cleaner

So then you've tried the machine he uses and know from experience it is inferior?

FYI @millercarbon the cleaner in question is an Odyssey MKV, very well regarded and similar approach to the Monks and Loricraft machines although the Odyssey is built to Teutonic tolerances 😉. Personally I like the speed and simplicity of my US machine but I might like to have a Monks as well for those discs needing a real deep clean 😜

@millercarbon,

Forgive me if I'm wrong but judging by your post above, you don't have personal experience with US cleaning, and you're ready to recommend the Walker fluid without personal experience.  All the while, ready to question others' experience?

I use a Monks Omni and ultrasonic. The results are synergistic. I talked to the Degritter people when they first announced the machine a couple years ago, and suggested that coming in at a low price point might give them a real edge in the market. At the time, the person I spoke with was not optimistic about keeping the price down, but wanted to build a better machine. Perhaps they have done that.
In the meantime, an awful lot of people have hopped onto the DIY bandwagon, and not just for lower cost. The feature set can be better, and if you add a circulation pump and filter, you can really optimize what you are doing. I know @slaw has gone this route, @Terry9 has done so, as have a few others. Rush Paul wrote that seminal article bringing together a lot of the learning on the DIY Audio thread (a vast undertaking to read). Tima has contributed several articles on the subject as well, including some thoughts on filtration and water purity.
The high frequency used by the Degritter is, as far as I know, novel among the current crop of US machines used for record cleaning.
The Walker fluids are fine. I get the same results from AIVS #15 and reagent grade 1 bought in bulk and it takes far less time than the 4 steps involved in the Walker Prelude kit.
I hope these folks can bring it to market and succeed, in spite of the price.
Too bad the Odyssey is no longer made. I would have bought one. The Monks is pretty well made, relies on a German dialysis pump and has a sort of classic British engineering vibe to it (no, it doesn’t leak oil and the lights don’t go out). There’s the Loricraft too, and I think Fremer wrote up at least one other point nozzle at a lower price point.
In my estimation, you don’t need fancy equipment to get the job done. Most of it is about method/process and good practices. An all in one machine that works with the push of a button has yet to be made cheaply.
