Hi David,

Our ingredients, within proprietary constraints, are listed on the bottles.
After more than 20 years of evaluation & use most of you still question the
safety & thoroughness of a system that has cleaned 10s of 1000s of vinyl,
shellac, lacquer, acetate & Edison Diamond Disc recording & has received
wide positive review & most of you have never personally evaluated.  The
LOC solution is a "do no harm" solution incapable of thoroughly cleaning
phonograph recordings based upon chemistry not jive.  We provided, on
numerous occasions, full disclosure of our products & nothing but excuses
have prevailed.

Furthermore the LOC preservation unit has had multiple samples of these
materials for over 12 years & managed to loose them & never evaluate
them.  It's outrageous that they would now offer such an inferior solution
of their own concoction with little or no long term evaluation.  Somehow
chemistry doesn't matter.

No one can fault the safety of our formulation based upon the chemistry of
the solution with respect to the substrates being cleaned, at least not
anyone with a minor amount of appropriate background.  And the end result,
that is listening to the discs will make you acutely aware of the value of
such cleaning not to mention the total lack of negative remarks about
materials that have been in the international market since 1992.

Somehow none of this matters to most of you as you wait for someone else's
approval.  Hide behind whatever documents you wish but in the long run you
neither preserve recordings by leaving biological feed stocks in the groove
than you can appreciate the real quality of the recording by listening to
it in its original dirty condition.

As a group you're offended by the presence of a commercial enterprise but
with out our efforts how would you be any wiser.  In all candor, I'm
disgusted by the waste of time & effort spent in our efforts to preserve
recorded sound.  An effort that has kept me from cleaning much & listening
to much of my own collection for decades.  It's obvious that I've wasted my
time & efforts.

Many of you hear digital recordings as equals of the best that analog has
to offer.  BULL!!  If you can hear then you don't care but that's not the
measure of a reference point.

The LOC speaks & everyone follows, speak no evil, hear no evil!!  Shame on
you.  It's to bad most of you do not appreciate the one consistent feature
of the history of recorded sound - the sound didn't matter, only that there
was a new product to sell.

Happy listening as the bugs eat away at your prized collections.

Duane Goldman

PS   wait til you hear the results of thorough cleaning of lacquers prior
to plating for a realization that we've yet to hear all analog recording
has to offer.
