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.

Drubin,

The Axiom everything matters especially applies to cleaning records and the sonic results that are yielded.
.
I use a separate brush for each fluid and or rinse that I do. I don't want to cross contaminate from one step to another. Using "Ultra-Pure" water matters dramatically in each step (either as part of the cleaning solution or as a rinse).
.
Using a strong vacuuming machine (Loricraft or other) is important in that you need to remove all of the cleaning/ rinse solutions off of the record to take the impurities /dirt/ mold out of the grooves.
.
My great preference is the AI solution system as I have mentioned before. Walker's system is quite good as well. The more resolving your system the more you will appreciate the value of good cleaning / rinsing solutions and a great machine.
.
Good Luck
