Re: [ARSCLIST] Record cleaning fluid recommendations?

[ajs6f@xxxxxxxxxxxx]

There have been a number of positive anecdotal reviews of this offering
(the Disc Doctor fluid) provided to the list. I'm wondering if anyone
out there, particularly Mr. Goldman, can provide some kind of data
comparing this against an example of the popular distilled water /
Photoflo / surfactant combinations? Microscopy or any kind of
quantitative measurements? If the sentence:

is a claim of special quality for this particular product, is there
some kind of objective historical data to demonstrate this?

I checked the www.discdoc.com website to no avail, but perhaps these
things are available elsewhere, or by request?

I'll be amongst those waiting with interest for the more detailed
commentary.
