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.

@bigtwin,

+1 Amen.  My thoughts completely.  Once cleaned, the only thing that belongs in the groove is the stylus.  If you are curious I expanded upon this thought here - https://www.whatsbestforum.com/threads/timas-diy-rcm.26013/post-740686.
But, but, but, but...blowing or gently exhaling on a record before play? Wouldn't it be better to use one of those small personal fans, instead? I would think a person exhaling, even gently so, on a record would have the propensity for depositing, sooner or later, fine atomized droplets of saliva, vapor, CO2, O2, Nitrogen and whatever else comes out of one's lungs... no? I understand and respect the zeal to achieve and maintain pristine grooves but blowing on a records seems counterproductive.
Right. Do not even so much as breathe near your precious vinyl. This will raise humidity levels unconscionably high, possibly even getting moisture on the vinyl, necessitating another year of slow gradual careful drying. For this reason records must be stored in a cabinet outside the listening room where no people ever enter. There should be a small slot in the wall close to the turntable through which only the selected record is removed WHILE SLOWLY INHALING so as not to risk contaminating with your breath.

The thought of anything less, no I cannot even go there. https://youtu.be/VKcAYMb5uk4?t=8
@oldaudiophile,

I use the Orbit HEPA Blower https://photosol.com/products/orbit-hepa-blower/, which has a suction-side HEPA filter and a silicone air-bulb, to blow lint off the stylus. Not enough air flow to remove dust/lint from the record.  However, some people use the Amazon.com : Giottos AA1900 Rocket Air Blaster Large - Black : Camera Cleaning Kits : Electronics to remove dust - its moves more air.  

Otherwise, as I wrote in the book "VI.11.c" I use the Kinetronics™ Tiger anti-static lint-free microfiber cloth Anti-Static Tiger Cloth | kinetronics as a swipe (just lightly touching the record surface) to essentially brush/dust the record to  remove surface lint and particulate without penetrating the groove. Also, the orange color of the cloth allows easy observation of any fibers that may be deposited from the cloth.  The  Kinetronics™ Tiger Cloth can pickup dust/lint but being anti-static it does not tightly hold the dust/lint - so a quick shake (arm reach away from the record) and the dust/particulate is dislodged from the cloth (as verified with UV light).  This keeps the cloth clean for next use.  
@miillercarbon, too funny!  Loved the video clip! If no one ever enters the vinyl inner sanctum, how do the records get there? Automation? Level 4 Lab protocols? Then again, the slot in the wall would violate those protocols. Perhaps retro-fitting an old jukebox for the wall transfer would be an acceptable trade-off. Gotta watch The Andromeda Strain again!

@antinn, that Orbit is a neat little device. No pun intended! The Tiger Cloths are interesting, as well. I've been using another brand in my cleaning process but only to absorb most of the fluid after cleaning, without wiping. After that, I just prop the records up for complete air-drying. That Clean Room sponge was/is intriguing, as well.
