Premium distilled water for ultrasonic record cleaner


I have a kLaudio lp200 ultrsonic record cleaner

I recall a few comments on reading threads about some special high grade distilled water

i can't seem to find anything via an audiogon search
klaudio says plain distilled is what they use

woukd anyone like to chime in with recommended top grade distilled waters
what properties make these special water brands stand out and the advantage to the sound of the records

a link or two would help

on a side note Klaudio is having a sale on their silencer and I went ahead and bought one
anybody using this silencer?

thanks

I don't purport to claim some 'magic' improvement in sound as a result of water (or even fluid for that matter). What I do hear is the difference between an old record that has an unknown history of contamination (including previous haphazard cleaning) and one that has been properly cleaned. My experience has been - using only ultrasonic was insufficient for some records, that multiple cleanings using different methods yielded an improvement and that the results are often more in the method than any particular product. Since many of these records are from the '50s and '60s, some are quite valuable, and I listen to them (I'm not just a collector), I want to achieve the highest state of playback as possible. In addition, since I don't want any chemical residue from fluids to remain on the record over time--which can potentially interact with inner sleeve material, etc.- I want to do my best to preserve them. Thus, the reason for using high grade water in various rinse and cleaning cycles. As I originally noted, it may be overkill.  I have no commercial interest in any product or company. My explorations of various cleaning methods are published, along with my visit to Culpeper and interview with the preservation folks at the LOC re cleaning. I do not believe that any of this borders on the absurd but you are free to decide otherwise. The only caveat I would make in evaluating cleaning methods and products is to perform some comparisons using different cleaning methods and combinations- something that is not easy to 'test' scientifically, since every record is sui generis in its pressing quality and history of contamination and multiple cleanings, even using the same method, usually yield some improvement up to a point. 

nice insight Whart

I to am there to play - not collect records

The ultrasonic brings so much more detail to the recordings and removes nearly all the pops and static on even new records.  I also have to buy a lot of used records that sometimes are vg grade. The Klaudio nearly always brings them up to a excellent level sound wise.


Having a solution that might squeeze more out of this is worth doing.

It's not bragging rights, it's protecting and enjoying your recordings

I run the ultrasonic record cleaning service Record Genie and use 2 Klaudio machines, plus 2 Audio Desk machines. I also have a VPI 16.5 which is useful for pre-cleaning very heavily soiled or moldy records before doing any ultrasonic cleaning steps.

Audio Desk recommends using only "supermarket" distilled water for some reason, but I was curious about using purer "lab grade" water in the Klaudio machines in the hope of getting even better results. I've always used distilled water from CVS (which is also filtered to 0.5 micron) but just like Whart, I bought some NERL "lab water" from Optics Planet.

I bought 3 grades of NERL of varying cost. The 2 lower grades came in 5-gallon "cubitainers" (LDPE bladder in a cardboard box) at about $8 and $12 per gallon. The top grade came in 6 x 1-pint bottles and was more than twice as expensive. This was back in 2013, and the water had to be delivered to my business address because lab water is (or was) restricted from being delivered to a residence since it is required for certain illegal manufacturing activities!  

I asked some of my customers if they would like to try "lab grade" water, and clearly marked those records as such, running one Klaudio with CVS water, and the other with NERL water. Only one of the half-dozen customers that I worked with on this "testing" expressed a preference for the records cleaned with the more expensive water. I didn't charge anything extra for using the more expensive water.

In scientific terms, I'm sure my "experiment" was seriously flawed due to a tiny sample size if nothing else (only 6 customers) and I've gone back to using CVS distilled water in my Klaudio machines since then as I couldn't really justify the additional expense of the lab water.

One other thing, I use a TDS meter (total dissolved solids) to measure how clean the water is, rather than just using a "fixed interval" of x-records between water changes. It's quick and easy to drain a beaker-full from the Klaudio's drain spout every 10 records or so, and pour it back in afterwards, with the small funnel. A quality meter only costs about $60, so I highly recommend using one to ensure consistent and repeatable results..     
Dave- I think the 'uber' expensive stuff has labels like 'ultra pure' and goes beyond the so-called Grade or Type 1 Water; never tried it, b/c it is crazy expensive. (I think it may be used for injectable solutions, among other things). Yeah, they still require a business address- I used to use my law firm, which seemed to foreclose any question. I like your idea of using a TDS meter (which you mentioned in another thread), particularly if folks aren't pre-cleaning and rinsing records before putting them into the ultrasonic. I'm not surprised by the outcome of your experiments. For what it's worth, the pricing of some of this lab water is all over the map in the States, depending on the supplier and quantities--costs more for multiple smaller capacity bottles (obviously, just for packaging and handling) than larger quantities. I don't use enough of it to justify a water purification system. I think the better investment would be a small nuclear reactor in my backyard for cleaner power. Haven't checked  government regulations on that front. Be well,  :)

The impetus to use hyper clean water for record cleaning predates the ultrasonic machines.

That's a thread from 2008 that discusses the topic and NERL water.  Part of the problem with buying fancy water is the cost of shipping it while buying enough to be cost effective.  And of course some brands charge a lot more;  generally water from record cleaning solution manufacturers is much more costly. Five gallons is roughly 44 lb. to ship (unless the container is glass, then it's lots more.)   In '08, I was buying 5gal of NERL 9805 Reagent Grade Water at $34 shipped, but I could have paid more.  It pays to shop around.  And be cautious about interpreting different grades and costs as one being superior than the other.  Compare the labels.
