Thumbs up for ultrasonic record cleaning

You may find this explanation of different purification processes helpful:  [url]http://www.emdmillipore.com/US/en/water-purification/learning-centers/tutorial/purification-techniqu...[/url] The source is a manufacturer of equipment used in labs and hospitals.
In my interview with the LOC, the preservation specialist suggested the D/I was sufficient for records, the main objective being to remove mineral content. 
I've been told you can buy reagent grade II at places like Cosco. 
The reagent grade 1 cannot be shipped to a residence. It's also more costly. I now only use it to mix fluids and for rinse steps on the Monks. I used standard supermarket distilled in the US machine. 

This discussion, has been most helpful for me.

I only hope others will find it in a similar way.

Thanks so much to terry9!

I apologize for digressing, but JA and his buddy Kal Rubinson still insist that Benchmark DAC's are among the best and yet consumer after consumer on the various audio Boards express their regret for having bought one.

AFAIK, I have never reviewed or commented on the Benchmark DAC in Stereophile.
