Record Cleaning Machines


Has anyone out there done an A/B comparison of the cleaning results or efficacy using the Degritter ultra sonic record cleaning machine which operates at 120 kHz/300 watts and an ultrasonic cleaner that operates at 40 kHz/300 or 380 watts (e.g. Audio Desk; CleanerVinyl; the Kirmuss machine; etc.)?  I have a system I put together using CleanerVinyl equipment, a standard 40 kHz ultrasonic tank and a Knosti Disco-Antistat for final rinse.  I clean 3 records at a time and get great results.  Surface noise on well cared for records (only kind I have) is virtually totally eliminated, sound comes from a totally black background and audio performance is noticeably improved in every way.  Even though the Degritter only cleans 1 record at a time, it seems significantly easier to use, more compact and relatively quick, compared to the system I have now.  I'm wondering if the Degritter's 120 kHz is all that much more effective, if at all, in rendering better audio performance than the standard 40 kHz frequency.  I don't mind, at all, spending a little extra time cleaning my records if the audio results using the Degritter are not going to be any different.  I'm not inclined to spend three grand for a little more ease & convenience and to save a few minutes.  However, if I could be assured the Degritter would render better audio performance results, even relatively small improvements, that would be a whole other story.

Nice clip MC, as usual you are always spot on with the hilarious exaggerations from movies or TV shows.

@oldaudiiophile - I didn’t imply that the fan would hurt anything. I was just saying that if you don’t ever wet the record, you wouldn’t need a fan to dry it. You answered my question about frequency of cleaning, thanks. So I would buy a RCM, clean my records once and then forget about it unless I got a dirty used record (which wouldn’t happen)? No thanks.

 Like I said, I tried it on a wet RCM a couple years ago on 40 year old records played hundreds if not a thousand times and could not hear any difference before or after, nor did the salesman trying to sell me one. I think it was like $700, maybe a VPI? Maybe an ultrasonic would be better, but if I don’t hear any surface noise, are you saying the SQ improves with better dynamics, bass, clarity, etc. after being cleaned? I find that hard to believe if the record has been well cared for and has been brushed for dust, but I accept that you heard it.

That’s why this forum is so great, we can respectfully disagree knowing in this hobby it is very rarely cut and dry. A little comedy never hurts either to counteract the network news hysteria of the day.
@sokogear, it's all good!

Some folks with 35 kHz to 80 kHz ultrasonic RCM are comfortable cleaning records more than once. For now, I'm in the one & done camp with my 40 kHz machine until or unless I find the sonic performance of a record I've cleaned has deteriorated. So far, that hasn't happened. If it ever does, I don't think I'd risk a repeat cleaning on those records in my collection that are irreplaceable. I'd likely experiment with a record I know I could get a good re-pressing of. However, 120 kHz machines, like the Degritter, are purported to be more gentle. As such, some audiophiles are very comfortable running records through machines like that multiple times. This is another reason why the Degritter intrigues me. However, like you, I gotta hear it to believe it. I'm not inclined to shell out 3 grand for the Degritter or a machine like it if I can't be reasonably assured I'll get better sonic results than I'm getting with the machine & system I'm using now. The system hardware I'm using now cost me less than 400 bucks 4 years ago. Even if I added the cost of all the extra doodads I use in my system (e.g. fluids; microfiber cloths; etc.), I'd still be under 450 bucks. I could order a Degritter from Music Direct, do an A/B, see/hear for myself and send it back if it failed to impress. They have a great 60 day return policy. Don't know if they have a restocking or return fee, though. I'd have to check that out. Still might be worth it. It's looking like this may be the only way for me to satisfy my curiosity, unless I can find a local audio shop with a Degritter who cleans customers' records as a demo.

Next time you've got about 45 minutes to blow, have a look at this:

@oldaudiophile years ago when I was looking at a 40khz unit (which I bought) I scoured the internet regarding the safety of ultrasonic cleaning.  I read a report of an audiophile who took a record he didn't care for and cleaned it ultrasonically over 100 times with a similar unit. He never saw any debris in the tank and reported no loss of sonic quality. So, I think we are ok with multiple cleanings if necessary.  I have cleaned my records with several different modalities and have never noted a degradation in sonic quality, only improvements.  I did recently purchase a Degritter and use it as a final step and believe I see an improvement in sonic texture and imaging, not so much pops and ticks.  These lps have meticulously cared for and cleaned prior to the degritter and if you have a revealing system, I think you will be pleased. If you have a local dealer a test drive might help, but the improvement will unlikely be earth shattering with an lp that is already cleaned.  I have a very revealing system and have seen improvements with records that have already been cleaned with a VPI, 40 khz US, and a clearaudio double matrix.  There is a utube video from Suncoast Audio demonstrating the improvement with a Degritter on an lp that was previously cleaned with the double matrix.  Hope this helps.
Hi, I just received Kirmuss and do agree with some comments above that water becomes hot too soon and one of my records (out of about 40 cleaned so far) wasn't sitting in the slot properly and there was risk of damage but I noticed and resolved this quickly. It appears from videos that it's better to insert records while machine is working. Process is a bit time consuming but perhaps based on condition of specific record you can make changes to it (here I'd like to hear feedback from other owners). One cycle with surfactant maybe enough for many but some might require 4-5 times. Also I'm skeptical about steps after wiping out record and typically finish cleaning process with applying Furutech destat. I can afford more expensive cleaner but generally think about it as of waste of money as with proper experience can get desired results from Kirmuss.
@orthomead, thanks for the info and feedback! Truly appreciated! With regard to the issue of a revealing system, I certainly do not have a Mikey Fremer state of the art system. However, my MAC amp, Revel F206 and Mofi Ultradeck & Mastertracker are as revealing a system as I've ever owned.

I've just recently found a shop about 2 hours' drive from me that has a Degritter on demo they use to clean customers' records. I'm going to explore that. I'm going to bring a couple LP's I've already run through my US cleaning process, a coupe I haven't and see/hear what happens when I spin them on my TT. If the comparative sonic results are a significant enough improvement over what I'm achieving now with my lash-up RCM system, that will spur me into doing battle with my financial comptroller (i.e. She Who Must Be Obeyed). I'll report back in to let everyone know what comes of this. Push come to shove, I suppose I could use my present USRCM as a final rinse and use my Knosti as a pre-cleaner for the old records I inherited.
