I was able to track down Geoff recently, and I'm sharing this
information he sent me with the list ... maybe helpful ... etc.
This was his reponse to my question if there was any other
commercially available detergent solution that could be used to clean

There is a good reason that I recommend Labtone (and only Labtone)
cleaning wax cylinders. I tested a number of lab detergents and
consumer-type cleaning agents for cleaning wax cylinders in
for transcribing the 3000 cylinder collection at the University of
California P.A. Hearst Museum (then called the Lowie Museum)at
I was dealing with a mixed collection of commercially cut cylinders
had been shaved and reused (of many different wax compositions),
Dictaphone cylinders of various types, Ediphone cylinders, etc.
the things I wished to remove by cleaning were mold residue, all
unidentified grunge, and compounds leeched/exuded out of the wax over
The requirements were simple; the cleaning process had to be: low-
(we had little equipment or money), simple to accomplish, without
critical operations, thorough and effective so that all the
were removed, and leave no chemical or physical residue. Labtone,
formulated to remove organic residues from glassware and rinse clean,
the job very well. Other lab detergents did not remove the
as thoroughly, and/or left some sort of residue (usually a
wetting-agent). Consumer-type detergents contain a whole host of
chemical agents intended to be residual, such as wetting agents,
or color enhancers, glycols, etc. Photo-Flo, a wetting agent used
photographic processing, did not clean very well and also is intended
remain on the surface.
I used Labtone solutions (about 1%) to clean 3000+ cylinders at
and the same process was used by the Library of Congress Folk Life
Project to clean their 9000+ cylinders, and Indiana University
of Recorded Sound used it to clean 7000+ cylinders. Both these
collections also borrowed and used the same transcription deck I had
built and used to transcribe the collection at Berkeley. A similar
project in Ireland specified the same cleaning process, although it
have used non-contact transcription technology; unfortunately, it was
As far as I am aware, there has not been any cleaning agent suggested
a replacement for Labtone since I first used it in the 1970's. I and
others have also used it for a wide variety of disks, including
aluminum, glass, Bakelite, and others (but not shellac, which can be
sensitive to water). I still use it for CD's.
The procedure is quite simple:
1. Mix up a tepid solution of Labtone in purified water. Add
dissolve the Labtone until the solution feels slippery.
2. Dip the cylinder into the solution to wet it (hold it with
fingers in the mandrel hole, but don't let it go).
3. Dip a piece of polyester velveteen (about 3x6") into the
to become saturated.
4. Lift the cylinder above the solution and gently drag the
velveteen around it so that the pile of the fabric gently "scrubs"
the grooves. The idea is to let the weight of the saturated fabric
do the physical cleaning -- do not press or rub the cylinder with the
5. Dip the cylinder and examine to see if it appears clean. You
repeat the cleaning with velveteen as may be necessary.
6. Rinse the cylinder thoroughly in clear tepid running tap
7. Final rinse in a container of purified water or pour purified
water over the cylinder to remove any residue from the tap water.
8. Blot (not wipe) the exterior of the cylinder dry with a soft
lint-free cloth (old handkerchiefs work well) or high-quality soft
paper towel. The cylinder will not be wet after rinsing, but will
have some water droplets on it.
9. Stand the cylinder on-end on several layers of paper towel to
the interior air-dry.
You can obtain Labtone only from VWR, although it is possible that
independent lab suppliers can order from them for you. Their website
is <www.VWR.com>. Search on "Labtone". The smallest size is 8 lbs,
#21850-027, @ $36.15 plus shipping and handling.
This will be relatively expensive, but it really is the best
for the use. As I indicated, Labtone is great for vinyl records and
CD's, as well, and you can use it in your kitchen, perhaps for
glassware, also!!! I use it regularly for cleaning eyeglasses, as
as it removes grease but leaves no streaks, halos, or smudges on
Best of luck. Feel free to share this message with others who have
