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.

I can’t imagine using the Kirmuss system.. . Life is too short.

My understanding is that ultrasonic is not effective on removing grease and oils. Is this correct?

After trying various VPI type machines and a Degritter I use the Gem Dandy. http://hifigem.com/hydraulic-lp-cleaning-apparatusMKII.html. The others work, this is is just as good or better at a fraction of the cost

My records are dead silent. I took one over to a friends the other day and he got up to check after he dropped the needle because he didn’t hear any groove noise before the music started. I apply the cleaning solution then use a hand held steam cleaner to blast them before I rinse them with copious amounts of very hot tap water using the kind of hand sprayer most have on their kitchen sink. , so in my experience all the fuss about hot water is unwarranted. Thin records will actually warp during the process but go back to flat when they cool.

I do have a utility sink in the basement where I can splash some water about without concern. I would not want to do this at my kitchen sink.

BTW to keep my Degritter from getting too warm and going into cool down, as it used up the water in the tank I added ice cubes made from distilled water. You can also purchase a second tank.


Ultrasonic cleaning can be very effective against oils and greases, ...... . BUT, they need some chemistry to both lower the surface tension of the fluid to better wet the record

makes sense, but many claim they are using ultra pure water to great effect which does not make sense if the record has oil (fingerprints) on it. In my experience with an ultrasonic machine and distilled water these fingerprints were not removed.

How does grime get in there without fingerprints? Records are only exposed while playing, Then immediately put into MFSL rice paper sleeves.

What we've been told over the years is that in the process of stamping a record certain chemicals are used to allow the stamper to easily separate from the vinyl. These chemicals should be cleaned from a new record for optimal playback. I have no way to verify that. I do clean all my new records and they sound great so I will continue to do so.
