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.

Makes sense, the ad I found list 4 gallons in a case and a price of $105.95. and I can't figure if that gets all four gallons.
If it turns out to be $423.80 plus shipping for four gallons I will be forced to pass. I'm going to call tomorrow and ask for clarification.
FYI, The text says:
Our Price $105.95
Size 1 gallon
Qty/CS 4
Unit Case of 4
I appreciate your input and clarification. Also hope this ultrapure grade of water does not turn out to be $105.95 a 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). - |
Hi Albert: I just did a quick web search, coming up with Nerl Diagnostics Reagent grade with those numbers on the Nerl website without pricing and another website offering the Nerl water for sale with pricing.
If I'm not mistaken and reading the priced website properly there is no difference between the -1 and the -5; those numbers appear to be product numbers specifying the amount of water and number of containers (ie. 4 x 32 oz bottles vs 1 x 1 gallon or 5 gallon for example) but the reagent grade water appears to be the same whether -1, -3 or -5.
That being said, the Nerl site appears to show three grades of water with High Purity appearing to be the lowest, the Reagent Grade next and the "best" being described as "Safe and Sure Ultrapure Water". Unfortunately I could not find any pricing on the Nerl website or any other website that offered the "Safe and Sure". So that might warrant a bit more investigation and if the price was not outrageously more than the Nerl Reagent Grade (I would expect that it probably wouldn't be, at least in audiophile terms!), might be the one to go for. |
HDM, any idea about difference between 9800-1 and 9800-5 grades of Reagent grade water?
I looked on the web and there are several companies that sell this. |

You can buy a jug of distilled water at any reasonably stocked drug store. |
Ultrapure/lab grade/triple distilled/reverse osmosis water are NOT the same thing.
For example, while reverse osmosis is effective in removing a wide range of impurities including ions and distillation is another technique to head water in the right direction, ultrapure water (also known as Reagent Grade water) will typically involve 6 other processes including, softening, activated carbon filtration, micro/ultrafiltration, ultraviolet radiation, and deionization all done in a certain order to achieve "ultrapure" status.
Ultrapure is a step above Pure/Analytical Grade water and two steps above Pure/Lab Grade water. In my experience, Ultrapure is great for cleaning records. |
*Reverse osmosis water filtration system
- easy to install
- cheap in a long run
- DRINK AND SAVE - not only money. |
I have heard automotive stores carry it, although I have not checked myself. |
Not an expert here but wouldn't boiling water then running it thru a charcoal filter work? |
Any Pharmacy will likely have distilled and often including deionised water too and usually pretty cheap. I can get 4 L = 1 gallon worth for $2.00. |
To my knowledge the purest water (h2o, nothing else) is from a reverse osmosis filter. Aquarium stores sell it as it is used to top off salt water / reef tanks as water evaporates, but adds no minerals, chemicals, or anything else that may hurt the tank. They call it RO water, and in my area I pay about 50 cents per gallon.

If I were you I would investigate a reverse osmosis system for your home from a local vendor that installs on demand RO systems for drinking water. You could have a tap installed straight off the unit so the water is not traveling through household plumbing. I know that lab grade RO systems provide water that is much, much, better than any water that can be produced by distillation. I assume the home units are pretty good too. Purified water, once its dechlorinated, can go septic pretty quickly, so you want a system that produces it as you need it. |
