Ultrasonic Record Cleaner 40 v 80 v 120 kHz

@jwr159,

No I do not use UT. I do not clean enough records, and convenience is not something that is a priority to me. The manual process leverages chemistry (detergents & acid, Liquinox, Citranox & Tergitol) especially the acid that you would not use with the other cleaning processes and with the right brush and the right technique achieves a very clean record. But the manual sink method is technique sensitive and is not convenient and much beyond cleaning 6 records at a time is not practical. It’s pretty much as the book end of Chapter XII states:

XII.16 The final chapters of this book will discuss machine assisted cleaning methods: vacuum record cleaning machines (RCM) and ultrasonic cleaning machines (UCM). It’s important to consider that machines are generally developed for two primary reasons – reduce labor and improve process efficiency. Process efficiency can mean faster (higher throughput) and/or higher probability of achieving quality or achieving a quality that manual labor cannot produce. Manual cleaning in the appropriate environment with appropriate controls can achieve impressive levels of cleanliness, but the labor, skill, time and probability of success generally make it impractical for manufacturing environments. But for the home audio enthusiast, depending on your attention to details, adopting machine assisted cleaning may or may not yield a cleaner record. However, the ease of use and convenience provided by machines can be very enticing and cannot be denied.

But, let me stress, as the book Forward states - All cleaning procedures specified herein are presented as only “a” way to clean a record. No claim is made there is only one way to approach the process. In the final analysis, the best cleaning process is the one that is best for you.

Good Luck

Kirmuss sonic results competes with the best ultrasonic RCMs, but it's labor intensive. 

Audio Desk - long term established excellence, but pricier than the comparable Degritter.

Degritter - does it all for the most reasonable price

The Audiodesk_Pro is a very low powered UT device.  The manual Audiodesk_Pro_Manual-2018-7-Inch-Kit.pdf (galibierdesign.com) indicates an overall power of power 90W (which include the rollers) and a volume of 4.5-L which at best yields 20W/L but more likely 60W UT power for 13.3W/L.  Comparing against other 40-kHz machines, the HG max power is 60W, but the UT power is ~50W in 0.4L = 125W/L while the king of the hill, the KLAudio is 200W in 0.78L = 256W/L (the KLAudio is a beast).  However, the smaller tanks need more power because the ratio of tank surface area to volume is high, while the Kirmuss 35-kHz is about 165W and about 6.5L = 25W/L (it uses the same basic UT tank as the Isonic P4875 https://questforsound.com/pdfs/iSonic-catalog-P4875+MVR10.pdf.  

Speaking of iSonic, which of these two options would do a better job?

@jwr159 I am a long term user of Vinyl as a Source Material.

I am today a total advocate of the Manual Cleaning method supplied in Neil Antins PAVCR shown in the Link in earlier posts.

I am not going into the ’vs-this -- vs that’ debate.

Using the Guidance in the Document for Manual Cleaning combined with a 'few tips' from others contributing in another thread, along with my own teaks to the method. The Manual Cleaning Method has left myself with Vinyl LP’s that I now Class after having owned for 40ish years as being ’ PURIFIED’.

I am actually convinced the PURIFIED is an audible quality able to be detected

I now clean Albums that are Brand New Purchases and know what an improvement that is to be had on some.

Following Neil’s Guidance in the Document will achieve identical results, the tweaks referred to are really methods used for the applications of the Solutions and Rinse Methods.

As for a Tweak, I use a modified Lazy Susan to mount the LP, this is positioned over the Kitchen Sink. I also use Different Coloured Baby Scalp Brushes, for the different treatments for the solutions to be applied. A bowl is used as a DW rinse bowl for each of the coloured brushes, where I dip the brush clean, prior to each new solution to be brush treated when applied, this is a measure to improve on avoiding cross contamination. It suits my way of thinking this one as a practice.

I also use a Horticultural Gardeners Pump Up Pressurised Bottle for all DW rinses of the Vinyl LP. Again select the preferred Nozzle Setting and Jet Power Rinse the LP, totally suit my way of thinking.

Back to Neil’s Guidance, on old Vinyl Albums, I found the White Vinegar Treatment created an Album that had the edge in quietness.

More Important, when familiarised and organised, if the Space is available, 10 Albums are easily able to be cleaned in a Hour, with the first Three to Four Albums being ready to be replayed or put into the sleeve within 30 minutes of the cleaning having occurred.
