Absolutely - unless you go to the extent of rigging up a 1 micron filter, to take the gunk out of the solution.  My filter circuit goes out of the tank's stopcock, through a 12v pump, the cartridge filter and then back into (the top of) the tank.  I found (by listening) that I no longer had to vac the wet LPs, to get quiet sides.

So do you just vacuum the LPs or do you have a special LP vacuumer?

@Owen Y I think it may be the adhesive holding the shakers to the bottom of the tank.

 

It's mandatory to vac dry after the US machine! After cleaning over 400 records and varying my method to get best results, and trying to keep it as economical as reasonably possible, I use the 5 litre bottles of demineralised water from Bunnings, 5 ml of Ilford photoflo, and 35 deg. heat for 15 minutes in the machine. Records are only cleaned 1 at a time as I don't think the machine has the gumption to do more, regardless of the technicalities involved. The record is then removed from the machine and instantly vac dried. I've amazed quite a few people as to how well it works. Doing 1 record at a time has by far been the greatest improvement of any of the variations I've tried.

Youse are a patient dogg.....

Normally a special machine. The Record Doctor V is one of the cheaper machines around and is used by many here. https://www.analogplanet.com/content/record-doctor-v-vacuum-cleaning-machine-lets-your-fingers-do-walking

 

You can buy or make attachments for your regular vacuum cleaner but I have to say that the convenience of an all-in-one solution (like the record doctor) makes it much more convenient.

400 lps for 15 minutes is still only 100 hours use before dead.

 

Not really very good, if you ask me.

Like I said, I think the US modules are detaching from the tank. It still makes all the noises.

 

While on the subject of cleaning, do we have a method of removing poly bag haze? For the most part it's ugly and harmless, but some bags, especially the MOFI ones, really do some audible damage.

I have had my Ultrasonic Bath  since August 2016 and have used it for about four or five hours nearly every week,so about 500 hour, with no problem.

I even brought a second one when offed one cheap, just in case, but have not needed it.

 

Mine is set at 45 degrees for fifteen minutes and unless records are exceptionally dirty, I clean four at a time.

Yes it will clean one record at a time quicker and better but IMO, most records do not require this.

I thought the MoFi ones were a one off batch years ago?

There is no way to remove the haze.

There have been treads on here with some one suggesting you could polish it off but it did not work.

The hazing is cased by PVC outer sleeves and exposure to heat causing the chloride to off gas.

Polish would be removing the surface, not something I would recommend on a record.

I don't want to side track this thread 

But you are of course dead right. The guy was very serious though.

Some one on here did try it and ,not surprisingly, it did not work.

What cleaning fluid were you using (that you had to rinse off)?

 

And what was your cleaning machine?

 I use an Ebay US tank. The fluid was (off the top of my head as I haven't done it for a few months)

 

- 5L tap water,

- 50-100ml isopropyl alcohol,

- and 10-20ml ilfotol

Interesting!  IMV, the surface noise was because all the cr*p that the US process blasted out of the grooves is in suspension in the water - so when you let the record surfaces dry … the water evaporates and the cr*p gets left behind at the bottom of the grooves.

 

I avoid this by putting a 1 micron filter on my tank - others, instead, do a vacuum at the end of the US process.

 

It would seem from your experience that a clean-water rinse also removes the cr*p from the grooves … so how do you go about the rinse process?

 

And can I suggest a slight change to your mixture:

  • 5l water
  • 250ml IPA (5%), and
  • 5 - 10ml Ilfotrol.  (Just enough to make the water 'sheet off' the surface when you lift the LPs out of the tank; if the water runs off in rivulets - rather than a continuous sheet - you need more Ilfotrol.)

Thanks Andy. I suspect that is not so much crap in the water but rather too much ilfotrol.

I mostly just wet vac my records now unless really dirty as the US cleaning is a bit of a process. I don't have a dedicated place for it so I set it up in the ensuite for a whole day of cleaning. My wife understandably gets a bit antsy when I do this as it takes over

I think you're correct about too much Ilfotrol. I US at 35 deg c so don't use isopropyl as it would just evaporate away. Earlier on I did, but I have found no difference without. Water rinsing after isn't an option as our water supply is way too hard. I don't even drink it.

@andyr I'm curious: what's the benefit of the isopropyl alcohol?

 

I always used it with my Nitty Gritty wet/vac machine, Murray - so I just kept on using it with my US tank.  Alcohol attacks the contaminants that might be on the LP surface.

 

Although the %age is much less (for my US tank) as I read somewhere that the flash point of a 5% IPA solution may be reached at just above US tank temperatures!  (I used to use between 1/3rd and 1/2 IPA for my Nitty Gritty solution.)

 

Interesting point t-mike makes about the 35 deg temperature evaporating the alcohol.  I'd never thought about this - but I'm sure Mike is correct.  So I need to keep adding IPA to the tank as the cleaning cycles progress!  :lol:

 

Is there an easy method I can use to measure the %age of alcohol in the solution?

      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

      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.

      Item: RCM Sensor 2 Phono stage + Kuzma Stabi-S Turntable (with PS2 speed controller) + Stogi-S Tonearm + Lyra Delos Cart
      Location: Mount Martha VIC, 3934
      Price:
      RCM SENSOR 2 = $3800  - SOLD (TT still available)
      KUZMA STABI-S TT + STOGI-S tonearm + PS2 Upgraded Power supply + LYRA DELOS MC Cartridge = $6750
      (comes with free perspex dust cover, as per photos)
      Package Deal: $10K (RRP for this setup is approx 15K. Please note I prefer to sell this whole package COMPLETE)
      Item Condition: 9.5/10
      Reason for selling: Have purchased a new car and need funds for that.
      Payment Method: Cash on Pickup or Bank Deposit. Paypal is my last preference and you will need to pay an extra 3%.
      Preference given to local pickup VIC buyers.
      I can send interstate at buyers expense, but very much prefer not to because of risk of damage.
      Extra Info: I bought these last year from Sonic Purity in May 2018, so this gear is approx 1 year old.
      The sale is somewhat regrettable, however I have other priorities now.
      The RCM Sensor 2 phono stage is magic and extracts every detail from the Cartridge while giving strong bass.
      (Has Furutech Connections, and external latest power supply)
      There are many reviews online about the phono stage and many who have heard it will confirm its high reputation.
      It has a multitude of loading and gain options.
      https://sonicpurity.com.au/store/phono-stages/rcm-sensor-2
      The Kuzma Turntable is equally amazing in sound and build quality.
      Latest 2018 30mm thick platter!
      https://sonicpurity.com.au/store/turntables/kuzma-stabi-s
      It has the upgraded power supply which means you don't need to change pulleys etc to change the speed.
      The speed controller has a digital display.
      It comes with Stogi-S tonearm, and LYRA DELOS cartridge. (has had little use, but is run in. I honestly don't know the hours)
      Those who know this cartridge can tell you that its super detailed in the high frequencies and still has gorgeous midrange and strong bass.
      Cartridge azimuth has been painstakingly set up by Rom at Sonic purity, using computer software.
      I look after my equipment with a lot of care and live in a smoke free / pet free home.
      Auditions are welcome at my home only for SERIOUS BUYERS.
      Upon sale I always make donations to SNA.
      Thanks for watching.
      Cheers,
      Paul.
      Happy Easter to all.
