@maximumheadroom had Kirmuss myself while I didn't have the issues you had it was a PITA to use and had too many "steps" for the process. Kept it one week and sold it quickly at a loss. Live and learn. Now use a keith monks cleaner and couldn't be happier.
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. |
If you handle records properly and remove the dust with a carbon fiber brush properly before each play, the need for a RCM seems to be greatly reduced. I guess if you buy a lot of used records that are very dirty, it could come in handy. How does grime get in there without fingerprints? Records are only exposed while playing,Then immediately put into MFSL rice paper sleeves. I tried a RCM a while back (forget what type-around $700) on my oldest records (although they were in very good shape) and could not tell the difference after they were cleaned, playing them immediately before and after. I remember a long time ago an engineer who ran a high end audio shop told me not to put any liquid on a record - just use a carbon fiber brush and it has worked for me for 40+ years. |
I cleaned a number of Blue Note originals ( some of them scratched and therefore VG to VG+ copies) on the Kirmuss. I used only distilled water, nothing else. The results were interesting, a slightly cleaner looking LP, but SQ was exactly the same as prior US clean. ( I had cleaned all of these on my prior VPI 16.5). Here's the thing, IF you are collecting older pressings, the probability that they are scratched and noisy is very high, no record cleaner can address this.Period. The Kirmuss method will not stop the record from sounding noisy if it is scratched or otherwise marred. Nothing will, IME. |
@herman, Ultrasonic cleaning can be very effective against oils and greases, and the lower frequency units such as the Isonic/Kirmuss at 35-40 kHz are preferred. BUT, they need some chemistry to both lower the surface tension of the fluid to better wet the record & soil and to add some detergency to emulsify/clean oils and greases. |
