The best method ever for cleaning records was sold for a while back in the
early 'eighties by Audio Empire (the "gold-god" turntable people). It
consisted of a tall, black plastic container with an "applicator" head on
top
and was filled with a thick viscous liquid that smelled vaguely of
photographic stop-bath. To use it, you turned the container upside down
and
squeezed until a blob of the liquid appeared on the applicator pad. You
then
applied the pad to the record in a circular motion until the entire side
was
coated (except for the label area). You then set the record on a towel or
other soft surface with the wet side of the record up. Left a few minutes,
the goop would dry to a solid film. Next, one took a piece of scotch tape
and
ran it from next to the label all the way out to beyond the edge, pressing
down hard for good adhesion. Then, holding on to the piece of tape, one
smartly pulled up the tape which would pull the film of dried goop off of
the
record. If any was left after that, just use another piece of scotch tape
to
dab the remaining pieces, but if you coated the record side well, it
always
came up in one piece.
The result was a record that not only looked but WAS clean as a whistle!
Records that had that gray, dull surface appearance before the "treatment"
were ****ny new looking after the film was peeled off. The peeled film
looked
like a clear negative of the record itself. It gets down to the bottom of
every groove, following even the smallest, most delicate undulation of
each
groove, surrounds and traps even the smallest piece of detritus, and
whisked
it away when peeled off. The record sounded clean too. Often quieter than
when new (because the goop also removed any mold release compound left
over
from manufacturing). I've never seen a more effective record cleaning
system.
I've literally made used records that were unplayable because of surface
noise become as quiet as its possible for a phono record to be!
I sure wish that it was still available.
