Thumbs up for ultrasonic record cleaning

Another way to describe how much of an improvement this has made...

I have, waiting for me around 30 newly purchased lps.
I'm finding myself gravitating towards my older lps to hear them like I've never heard them before.This is on my (free day)!

How's that.........?

Is pharmacy distilled a higher standard than Walmart distilled?

@slaw 

I don't know. But I trust them to meet spec.

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!
