Record Cleaner Advice?

@antinn did a good job of summarizing what is available as a "one button" type pop in the record and walk away type ultrasonic. @keegiam- you are astute enough to appreciate that the ultrasonic cleaning is not a complete solution and if you are buying used records (not necessary bargain bin/Goodwill sourced cast-offs), you may need to resort to manual cleaning (in combination with ultrasonic). The high cost of made for LP ultrasonics is what drove people to the DIY camp- which was, as far as I know, already involved in ultrasonic cleaning of LPs before the Audio Desk was first commercialized.
I think most of us experiment a bit, and based on results, find a method or series of methods that is effective and meets the needs of the user for both efficiency and cost.
Although the Monks was around circa 1970, and the VPI and Nitty Gritty came to market in 1981 if memory serves, my take is that it was only after the Death of Vinyl™ that people really began using RCMs more broadly since they were buying used records, including a lot of the audiophile stuff recommended by HP, Sid Marks and others (older RCA dogs, Mercury Living Presence, Decca, etc).
I honestly don’t know why I got sucked into the record cleaning area as a subject of interest. I had arranged to visit the intake facility of the Library of Congress located in Culpeper, Va. mainly to talk to them about cleaning, but the archives, old equipment, new technologies to read fragile media and the shelves of material on deposit and awaiting intake and accessioning fascinated me. I eventually published a piece on that visit which was one of the first of many on the topic (the recording cleaning part was really subordinate to story of the facility itself, but later installments on record cleaning followed).

Keegiam,
My answer to your question is different than Neil's.  For the ongoing maintenance of records that are in good shape to begin with I will continue to rely upon my VPI.  These machines do a more than adequate job of preservation, are extremely reliable and very easy to use.  Mine cleans in both directions under power, which I like, but even their most basic model 16.5 can clean counterclockwise manually.  All have a very effective vacuum drying system.  Current price for a 16.5 is about $650.

Well I need to interject here
My Vibrato, assembled in SC. Works on 80khz, (4) transducers, has a frequency sweep function, a heater. Retail is $875.00

Just had it refurbished. It's unclear if Louis will continue making these.

This site sells 132-kHz units -  CleanerVinyl Ultrasonic Record Cleaning.  I know of at least person that uses their 40-kHz unit for pre-clean and then the 132-kHz unit for final clean.  The individual has some physical limitations and this setup can pretty much clean anything.  

1. Step 1 - 40kHz; use the Tergitol 15-S-9 at 0.05 to 0.1%; for your 6000 mL tank that is 3-6 mL (no benefit for >6 mL/0.1%). For his 6000 mL tank he just adds 60-70 drops. This concentration will develop a wetting solution and micelles that will provided detergency. When he removes the record - gives it a few seconds to drain into the tank. As a wetting solution it will drain very quickly - this will minimize carry-over to the 132kHz tank.

2. Step 2 - 132kHz; use the Tergitol 15-S-9 at 0.01%; for his 6000 mL tanks that is 0.6 mL - to keep it simple just use 10 drops. For the 132kHz this is the final polish and the amount of Tergitol 15-S-9 is only to achieve a 'wetting' solution. You want the US and low surface tension fluid to do the work - he should not need detergency at this level.

I had an old nitty gritty that I thought did a good job. Then I purchased a Degritter and the improvement is clearly audible. I’m cleaning old records that I thought were clean but didn’t sound so good so rarely played them.  after using Degritter they now are wonderful. At first I used the included cleaning solution that came with the machine and was very happy with results. Now I’m trying Tergikleen to preclean records then using Degritter with just demineralized water. Not sure if it is better than the included solution but trying on different records. Highly recommended
