Finding ultra-pure water locally...

.
Sonically, there is a major difference between using "Ultra-Pure" water and R/O and distilled water.
.
I did a comparison between rinsing an LP using Ultra-Pure water vs. tripled filtered water that was then distilled 8 times.
.
The rinse was done on a record that had been first cleaned with a 3 step process using Record Research Cleaners followed by a 4 step Audio Intelligent process all done on a Loricraft RCM.
.
I took water that was triple filtered (ceramic/charcoal) and then re-distilled 8 times (each time the water was charcoaled filtered except the final & 8th time so as not to allow any charcoal particulates to enter the water).
.
I used my filtered/distilled water as a rinse (3 times) and then played the record. I then re-rinsed the record with the Ultra-Pure Water, listened again and there was quite stunned by how much better the Lp sounded (more detail , extended highs, and blacker backgrounds).
.
The Ultra-Pure rinse was audibly far better than my supposed very pure water.
.
“Ultra-Pure Water” is far different than R/O or distilled and easily worth the trouble and expense to obtain.

Yuo may be able to buy reverse osmosis water from an aquarium shop. The one I use for my fish tanks sells RO water for $0.25/gallon.

John,

You'll find everything you need to know (and LOTS more) on this thread: Finding Pure Water for Record Cleaning posted by user Justin_time. It is one of the great gems of this site, and a true magnum opus!

Thanks again, Justin_time, for a great piece of work (and I don't even "do" vinyl).

I believe John adams sunnyvale is asking about a product that has undergone an extremely more rigorous purification process than either RO or distilled water commonly available for sale in grocery stores. The ultrapure water is likely used in special laboratory processes. John, you might consider determining the uses for the ultrapure water, then contacting local area firms who do that type of work to determine their source. If you are simply looking for a gallon of the stuff to try, maybe one of the firms would sell you a gallon. If you are looking for a long-term source, maybe if you find out what supplier the local firms use, you could set up your own account with that supplier and they could drop off an occasional shipment to your residence or workplace since they already deliver in the area. Or, you could see what Albert comes up with and order from the source he uncovered. Let us know how it works for you.

I own an aquarium shop in Michigan. We use RO water in our reef tanks. I also use the water as a rinse on my VPI record cleaner. It works very well. I don't know anything about ultra-pure water, but I find it difficult to believe that it can be significantly superior to RO-DI water in purity. I regularly check our RO filter with a TDS (Total Dissolved Solids) meter. Our water fluctuates between 0-4 mineral PPM... I don't think that anything purer will make a significant difference for record cleaning applications. Laboratory applications? I wouldn't know...

Our shop sells RO water, 39 cents per gallon... We don't ship the stuff.

Cheers,

Ivan
