The fluid that I use (although purchased a large quantity second hand) foams like crazy when it is shaken, so it is more than distilled water. I also use a high intensity lamp to watch the dust fly off the pad when I brush it according to the instructions.
The formulas I use are old and purchased second hand (like the 8 oz bottle of D4, not D4+) foam like crazy when agitated, so it will not be pure water, and I would have to see the reviewer drink it before I believe it is water.
Not a reviewer - the patent says so.
Patent U.S.# 3951841
1. A phonograph record cleaning composition useful for loosening and coagulating particulate matter and inducing fungicidal activity upon the record surface without leaving any evident dry weight residue after usage, and consisting essentially of a fungicide of sodium azide in an amount of between about 0.0001 to 0.001 percent by weight, a nonionic surfactant selected from the group consisting of octyl phenoxy polyethoxy ethanol and nonyl phenoxy polyethoxy ethanol and included in an amount of between about 0.0003 to 0.025 percent by weight, and emulsifier selected from the group consisting of propylene glycol, ethylene glycol, and glycerine and included in an amount of between about 0.001 to 0.0125 percent by weight, an alcohol selected from the group consisting of methyl, ethyl, propyl and isopropyl alcohols and included in an amount of between about 0.01 to 5 percent, and the remaining part of the composition comprising a liquid carrier of water present in an amount of not less than 94 percent by weight, said alcohol being included to make the surfactant more soluable in said water.
2. The invention of claim 1 wherein the water is distilled water.
So---at least 94 percent distilled water by weight - expensive distilled water.
...and this was the "old stuff" that actually seemed to kinda sorta work.
I have used a bunch of record cleaners over 40 years of collecting. The C. Watts stuff was okay in that is did no harm. Original Discwasher sorta worked if used with care. The current D4+ unit is a POS.
If you want to actually do something that results in a CLEAN record - Discwasher is not it. As the saying goes "Been there, Done that, Have the tee shirt"
