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.

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.
@bigtwin - I'm sure the spit that hits the record when you blow on it doesn't help with the cleaning. Carbon fiber bristle record brushes (not the thick ones) sweep the dust off and have a blade (if you want to call it that) that removes the dust from the brush when you sweep it over that. I'll do a main sweep for a couple revolutions, clean off the brush and then do an angled sweep towards the middle of the record and then the blade sweep. If your records are not generating surface noise and you bought them new or are not trying to resuscitate an uncared for used record, then IMHO you don't need a RCM.

As far as using a fan @oldaudiophile, you shouldn't get the record wet unless as I mentioned, it is dirty. 

I do use a leaf blower.....WHEN DRYING MY CAR! Dirt on a towel will scratch the paint.

The dust on a record doesn't come from the road. Unless you handle the record like a gorilla and/or use paper or junky sleeves, it should stay the way you got it if you keep the dust off of it. Unless you have a ton of dust in your air, a carbon fiber bristle brush does the trick. I do keep the records in MFSL rice paper sleeves, and jackets in clear poly sleeves, and MFSLs have a folder that the record goes into that then goes in a jacket. 

For the ultimate in OCD, the original UHQRs  (DSOTM, COTC, FP, SPLHCB, IR, TFTT and a classical one) have the sleeve, the folder, the jacket, and then a box with 2 foam inserts to hold the record into the box. It also includes a frequency response graph inserted into an envelope on the inside of the box and the number of the pressing on an authenticity certificate and the actual jacket. Probably would cost $200 these days (before all the scalpers bought them and jacked up the prices). They just started making extra large poly sleeves which fit these and other small box set releases, so I use them on these prized records. So 5 steps just to put the record back and then one more to put it back in the cabinet! They sound pretty good too. Especially Finger Paintings, Sgt Pepper, and Crime of the Century.
