Our DIY Ultrasonic Record Cleaner


Owen Y

Recommended Posts

Hey guys, haven't had a chance to try this out yet,

I just have too many other things to do ATM.

 

I do plan to connect the two filters that i purchased in parallel, which should effective;y double the water flow rate.

Am am a bit concerned that the pump will not have sufficient pressure to produce a good flow thru these very fine filters.

 

I also have to figure out a mounting solution in case of leaks.

One of those shallow cleaning type tubs should be ok.

 

I'll keep you all posted when this has progressed.

Hi all,

I am just about to assemble my USCM and wold like to ask about the Triton solution.

Firstly, where is everyone getting it from?

Secondly, and more importantly, I have just read the MSDS for this product and would like to know how everyone is storing and handling this stuff?

It isn't good reading re: personal safety and disposal in particular.

Am I over thinking that the very diluted form I would use will be harmful to the environment / waterways?

Yes, I agree, I have studied the MSDS myself.

However, I figure that in diluted form & being pure detergent (without commercial additives such as bleaches, whiteners, brighteners, water-softeners, fragrances, colourings.... ;) ), that the Triton X-100 in diluted form is probably comparatively benign to our environment.

just tried my cleaner today ...kit from[mention=164463]Owen[/mention] Y ... fantastic.. had some records that I had bought second hand and they were barely playable..so bad that I was going to throw them out. Play really well now with barely any noise and some have no noise at all...hard to believe.

 

The ultrasonic bath was about $130 delivered (look around on ebay for the best price). So easy just leaving the records for 15 minutes. Makes cleaning a lot easier than a vacuum machine.

Hi @Toyboyo - that's excellent news.

I tend to clean for 25mins+ now, as the inner grooves have much less immersion time with rotation - see diagram on page 3 of this thread.

 

Hi @benny - quite a few members have purchased from Conservation Supplies in NZ:

https://www.conservationsupplies.co.nz/product/triton-x100-cle01/

There was mention of a NSW supplier but I can't quickly find the link now (shipping was fairly high as I recall).

LOL I never listen that far in to a record .... inner grooves always ignored ;)

 

@Owen Y in Victoria ... https://www.pacificlab.com.au/shop/products/tl125-500m-triton-x-100-lr/1/name  Triton X-100 LR  500ml  AUD$57.05 (Ex GST) BUT $39.50 delivery !!!! they do sell a larger bottle which might be more economic in regards to delivery

Assembly - those who are assembling this kit, it is pretty simple with just 4 screws (+ 3 motor screws), but these notes may help:

 

  1. You should find the following parts - 3 pcs of laser-cut stainless sheet metalwork, a threaded stainless rod with plastic square adapter for the motor drive, 4 red record spacers & a bag containing 2 black 'clamp knobs', 4 stainless button head hex socket screws + spring washers, 1 ball bearing unit.
  2. Strip off the protective plastic from the sheet metal plates.
  3. The large stainless 'baseplate' has 4 protruding nuts under, which should slide under the cleaner tank flange from the short end of the tank - if you have the correct tank.
  4. Attach the 2 upstanding smaller side plates onto the fold-down sides of the main frame, using the 4 screws + washers (align flush the bottom edges of the plates to the baseplate bottom edge) - the correct orientation of the motor plate to the smaller bearing plate is shown in the pic below. (Note, the pic shows a prototype unit & the metalwork has machine marks ;) )
  5. Motor - remove the black attachment plate from the rotisserie motor & use the same 3 screws & spacers to attach the motor to the motor plate (as pic below) - don't overtighten, don't strip the motor plastic threading.
  6. Assemble the record-rod with its clamp knobs & spacers (as pic below) - the little bearing just sits in the cutout in the bearing plate.

Done!

Cheers, Owen

Hi Owen,

 

Your spacers look great - can you tell me how thick they are?

 

 

Thanks,

Andy

Hi @andyr

(Sorry overlooked this....)

From memory - 23mm.

 

Cheers, Owen

http://darklanternforowen.wordpress.com/

 

Thanks, Owen.  They looked thicker than that - which was why I was interested.

 

Can you make them thicker?  (If you use a 40kHz US tank, for optimum cleaning there is supposed to be a 1 1/2" gap between the sides of the tank and the outer LPs ... and the same between LPs.  So one needs 35mm spacers.)

Although hardly conforming to any sort of scientific rigour, my trials with the original "Owen" spacers compared to 10mm spacers, my gut feeling is that there is no appreciable detriment to cleanliness by closer spacers given an increased cleaning cycle time.

As time per lp was nearly equivalent, given that closer spacers meant more lps per clean cycle.

 

Hard to do a proper test as you would need lps of the exact same dirtiness to do a proper scientific comparison.

I'm all for personal experimentation, Citroen, but I also take into account what other people write about.  What I've read says:

  1. cleaning efficiency is degraded when the LPs are less than a wavelength apart.
  2. cleaning efficiency is enhanced by there being more than a wavelength between LPs.
  3. it is probably a good idea to minimise the time an LP spends being subject to the cavitation bombardment in an us tank.
  4. so extra time to compensate for a reduction in cleaning efficiency by having LPs too close together ... is not a good idea.

So I will continue my search for some 35mm spacers.  ( @Owen Y  :winky: )

I guess its a matter of theoretically "ideal" and being practical. 

 

Ideally, I'd clean one record at a time. More than a wavelength apart between lps. So why not just do that and forget about spacers andyr?

 

Practically, I prefer to clean as many as possible for a given cleanliness ratio to time factor. 

 

"it is probably a good idea to minimise the time an LP spends being subject to the cavitation bombardment in an us tank."

PROBABLY, maybe, all conjecture.

 

Again, if you want to maximise your clean, by your research, just do them one at a time.

 

I'm very very happy to be more efficient and willing to risk any trade off by doing more at once for a longer time.

 

Each to their own...

Absolutely - each to their own, Citroen.  I paid extra money for a wide, 60kHz tank - so I could fit 6x LPs at a time, with a 25mm spacer between them (and between the sides).  I did this because it's obviously of benefit to clean 6 LPs at a time - rather than just 1.

 

Now, however, having read some recent posts on the DIYAudio us thread,  I'm just wondering whether I would get better cleaning with, say, 4 LPs in the tank.  Hence my search for 35mm spacers - so I can try this out.

Hi all.  I've been following this thread (and Owen's site) with great interest for some time.  It's time to take the plunge and sort out my own setup.

I was wondering 2 things:

 

1. If anyone in Melbourne wants to sell a setup, then get in touch!

 

2. There has been so much info and experimenting.  I was wondering if those in the know, if they had time, could possibly do a sticky (or similar) that summarizes all we need to know?  This may include:
- best (current) place to buy the Ultrasonic tub

- best place to get the rotisserie motor

- best place to get surfactant

- best combo of space vs number of records at one time

- best temp to set

- best recipes for filty op shop discs, to looked after older ones, to brand new pressings

 

Once a list is made, I imagine it could be updated as people discover improvements or ideas?  What does everyone think?  Such a great project and will only get better as more and more people report in with their successes, failures, and clever tweaks!

 

Thanks for everyone's hard work and I really look forward to getting into it!  Mat

- best place to get the rotisserie motor - Mine came from Kogan.

- best place to get surfactant - I read that Conservation Supplies in NZ no longer ships overseas?

- best combo of space vs number of records at one time - 3 records

- best temp to set - no heating required

- best recipes for filty op shop discs, to looked after older ones, to brand new pressings - the suggested 0.1% to 0.2% Triton X-100 dilution works well, 25 min cycle now recommended.

Hi @Mat-with-one-t - a sticky post or two would be good, but only admin can do that I think.

Some answers above (red text).

Another question.  I note that Triton X-100 seems to have all sorts of subtypes/grades.  Which one are people using exactly?

Just get the cheapest you can find. For our purposes, we do not need laboratory grade.

Let us know if you find this works better @andyr

 

What is the recommended minimum for a 40hz machine?

 

You could temporarily try 10 mm hex bolts to spread the records that extra 10 mm, just for experimentation to see if it is actually better.

 

All good stuff Andy, as I'd not come across this wavelength cf spacing theory before.

      Item Condition: Excellent Shipping Options: Pickup available and you can audition.,Shipping is included in price. Suburb or Town: Essendon State: VIC Payment Method: PayPal / Cash Reason for selling: No longer required Further information: Audio Desk Systeme Vinyl Cleaner Pro: The Audio Desk Systeme Vinyl Cleaner Pro is one of the first and only record cleaning machine that incorporates an ultrasonic cleaning cycle in addition to a more conventional mechanical cleaning via bi-directional rotating microfiber cleaning drums, and the result is the cleanest LP's ever. Unlike other record cleaners, the ultrasonic Vinyl Cleaner bursts millions of microscopic bubbles off the surface of the record all the way to the bottom of the groove, where no fibre is fine enough to reach. And among LP cleaners the Audio Desk System Vinyl Cleaner is unique in using filtered air for drying, rather than one of the static-inducing suction systems employed by other record cleaning machines. This vinyl record cleaner is fully automatic. The purchase price includes the 7" record adaptor kit.
       
      Item conditions excellent - minor cosmetic mark on front control panel (screw has been tightened too much during construction, and slightly cracked the Perspex frame. This in no way affects the operation of the unit, nor is it loose. - see attached photo. All original packaging and manual included, plus 1 x bottle of cleaning solution. Microfibre rollers have only had around 100 cycles.

      Item Condition: Excellent Shipping Options: Pickup available but audition is not available.,Shipping is available at agreed cost. Suburb or Town: Hawthorn State: Victoria Payment Method: Paypal, EFT, Cash on Pickup etc Reason for selling: Looking to upgrade and automate the RCM process Further information:  I have had the Kirmuss since August 2018 (locally bought in Melbourne, 1st owner), probably have done around 400-500 records in this time.  I also bought a Record Doctor v5 at the time to vacuum dry the records that came off the Kirmuss wet.  I found this way worked very well and you could clean a batch of 30-50 records (dependent on water cleanliness) in a few hours  You can clean 2x12 Inch records on the Kirmuss move those to the Record Doctor for vacuum dry and then lay the records out on lint free cloth for up to 1 hour to dry before putting into clean inner sleeves.
       
      The RRP of a new Kirmuss (same model) is now $2800
      Most original items are included, including the cloth, mat, plastic drain pipe, camel hair brush, instructions, a couple of extra cleaning pads, power cord
      Used consumable items originally included:
      1) The included cleaning fluid is included but is 90% gone but it really is not required (used for extra pre-clean).  In the Kirmuss I used a combination of Distilled Water, Isopropyl Alchohol and Kodak Photo Flo 200
      2) Stylus cleaning liquid that i never used, but it is missing
      3) a record cleaning brush supplied is not included
       
      Record Doctor v5
      Selling both together as the Record Doctor is basically a giveaway to use in line with Kirmuss
      includes brush, use guide and a full bottle of record cleaner
      Note the 2nd last photo, shows the plastic liner on one section is loose from MDF in top left corner.  Some glue would stick that back down
       
      Kirmuss is the original double boxes and the Record Doctor comes in the original single box with foam support

      folks, considering an ultrasonic record cleaner... of the more affordable variety... I am not planning to spend on one costing the same as a turntable.
       
      And with more than my own share of home projects going on and plenty on the to do list no interest to be dong anything DIY in this regard.
       
      So what are folks experience with Affordable ultrasonic record cleaning machines of the non DIY variety ...
       
      theres this nobsound one on amazon - any thoughts or experience ? 
      nobsound on amazon
       
      dont want to get one and find a waste of cash ? last thing world needs is more land fill
       
      any good experiences with anything out there (non DIY - please and affordable)

      Item: Okki Nokki MKI  MKII RCM (White)
      Location: Blue Mountains, Sydney
      Price: $520
      Item Condition: Excellent
      Reason for selling: NLR
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
       
      EDIT: This is a MKII and not a MK1, as I first thought. This means it is manufactured in China (not Germany) and has a plastic instead of metal wand. Apologies for any confusion caused !
       
      For sale is a MK II Okki Nokki record cleaner, purchased in 2014 from Krispy Audio. Included in the sale are wands for 12” and 7” records, a clamp, and dust cover. The cover and 7” wand are additional purchases and retail for $115 and $75 respectively, and the 7" wand is unused. The dust cover is a must IMO, as keeping dust from a RCM is pretty important !
       
      The unit has seen mild to moderate use, and there are months where it’s barely used. 
       
      For anyone not familiar with the Okki Nokki, it is a wet - vacuum cleaning system, and works by first agitating debris from the record as it rotates via a brush placed along the grooves. After a few rotations (the unit has forward and reverse) the wand vacuums the liquid away, leaving you with a clean and hopefully crackle and pop - free record. It can’t perform miracles and fix a record retrieved from a dumpster, but for gunk, mould, fingerprints etc... it does a good job.  And with the debris and detritus new records come with, it’s a good idea to clean everything, not just 2nd hand purchases. Your needle will thank you. 
       
      A few months after I received the unit, it had an issue with the vacuum cleaner which was easily fixed by a fuse replacement and was a common problem with this model. It has been trouble - free ever since. 
       
      The original brush is long gone, so you’ll need to grab something suitable. There are plenty of options, and of course you’ll need to arm yourself with a record cleaning concoction. 
      I’ll also throw in a back - up set of spare velvet strips, which attach to the 12” wand and should be changed about every 50 records. 
       
      Shipping is possible as I have the box for the unit, however I don’t have one for the dust cover and so preference is given to local pick-up.
