Best ultrasonic lp cleaner in 2020 and what surfactant best?

so many new ones.  ps advise
and i read that surfactant is hugely important.  Any expertise on that?
Just got my Degritter.  I had been using the Clearaudio ultrasonic cleaner at my local audio store.  I played and then "rewashed" several (so far) LPs that had been cleaned with the ClearAudio.  The sound is improved.  There is lower noise level, so more articulation, separation of instruments, more natural timbre and tone.  I often wondered what reviewers meant by "veil".  The Degritter lifts the "veil" providing a clarity that is throughout the spectrum. Bass is better and cleaner and treble is "crisp" and "bright" in the positive sense of the terms.
I am using the Degritter supplied surfactant.
Noteworthy:  The unit I purchased was used.  When I received it, it had washed approximately 2740 LPs.  I emailed the company prior to purchase and asked what the duty cycle (life expectancy) of the US generator and pumps was.  The company replied immediately informing me that they warranted the unit for 2 years or 10,000 (yes, ten thousand) washes and that I should purchase the unit.  After 10,000 washes, they would refurbish the unit.  The software is user updatable. Mine had the latest version.

The footprint is about the size of a shoebox, so convenient to place.

Note that nothing touches the surface of the record-- no pads, no rollers.  A mechanism turns the record by its edge.  No water reaches the label. The water is continually cleaned via an inexpensive and easily replaced filter which is if you want, washable. (Took me about 1 minute to change.) The company welcomes you to make your own filter (they suggest the material) if you do not want to buy the precut ones.

The unit is extremely easy to use.  (Easier than the Clearaudio)  Nice manual.  The cycles are very customizable.  Even the heavy wash cycle is nearly silent.  The fan makes as much noise as you want to tolerate-- the slower it blows, the quieter (which can be very quiet indeed, or reasonably loud on full blast), but the slower the longer to dry.  It remembers your preference, so a wash is merely pushing a button.

Since it uses just distilled water (about 700 cc per tank) and a small amount (1-2 ml per tank)  of their surfactant, the cost per record is very little.  (about 1-2 cents per LP-- each bottle gives 50 tanks and a tank is good for 50 records). 

Glad I finally got one.  Highly recommended.
I just received the Nitty Gritty Mini Pro 2 ..  It was never used but from the guy at Nitty Gritty the machine is 10 years old.  I used it on a few records. And then played them ... I think I heard a difference in sound but the crackles pops tics were all still there. I felt like throwing the machine out the window thru the glass...  I don't know what I'm doing wrong. And a degritter and that Kirmuss guy sure the machine is the easy part but then it's like you shave the record manually like 2 times... He's been called the snake oil in the business. Also the vacuum works like any other but the pump and dispenser doesn't really coat the record like your black painting a record with fluid... I don't maybe I should quit LP's and go back to singing in the shower.
I don't have 3,000 dollars for this degritter it sounds like the solution in record cleaning... What I'm dealing with I wrote above... You tell me... Since that guy made that 4000 ultrasonic cleaning machine all this other crap seems dated.
Its been a while since i have been on the site, but IMO, ultrasonic cleaning is very effective and if you don't mind building, they are actually easy to build. As for as solution, distilled water is the primary component as it should be ultrapure. no compromise on it. Second, i like a little 100% isopropyl alcohol if you can get it. No residue from it. 90, 70 or less will have water and may have other components (ie fragrance, etc). you only need a little 1-2%. IMO, the cavitation occurs more readily with a little Isopropyl. A good surfactant/detergent also is recommended if you have real dirty records. I like Triton 100 but tergitol , Kodak photoflow, or even a little dawn dishwashing detergent will work. you do not need much. one or two drops of triton goes a long way. I also like to rinse afterwards just to make sure there is no residues. I will air dry after rinsing with distilled water. Finally, the solution should be warm, about 100-125F that goes into the ultrasonic bath. That helps improve the action of the surfactant. I built a unit for less than 200 dollars about 8 years ago
