Dear shaker-ga:
Is it possible that “erobially” is misspelled. I have found many sites
that offer “recipies” for cleaning solutions in the care and
restoration of old documents, like the following site that gives you
step by step instructions using Calcium chloride solution and Sodium
carbonate, but none with the description "alkaline solution #
BB161879ZBC".
Can you possibly provide more information, alternate spelling, so that
I may find the product that you seek?

A few questions:
Are you sure that this is the exact combination of letters and numbers
for this alkaline solution?
How did you hear of this product? Have you seen it yourself?
Are you aware of a company that makes this product? (I was thinking
that "BB" could stand for a company name.)
Do you know specifically what this product contains?
In general, any additional information that you have about the product
might be helpful.

I am sorry, it's a typo: It should read " the cehmical components on
these papers are very poisonous and highly Toxic; It is EROBICALLY
COMBINATED therefore serious measures must b taken while cleaning to
avoid inhalation. Use gloves and nose mask"
A Tester alkaline solution # bb161879zbc was not provided. Maybe you
can use bb alphabets for #2 and z for 9 and b andc for #2 and try
getting an answer...?
Thanks,

Did the instructions you have quoted come from the manufacturer of the
alkaline solution to which you are referring? If so, what is the name
of the manufacturer? If not, where do the instructions come from?
Also -- do you need that particular formula of alkaline solution, or
could you use another alkaline solution that is suitable for cleaning
old papers and stamps?

Greetings. I believe the solution chemicals for which you search are
only available to a licensed chemist.
Using "cleaning solution old stamps" as my Google search phrase, I
discovered a site called JUNIOR PHILATELISTS ON THE INTERNET and the
site is located at http://www.ioa.com/~ggayland/junior/watermarks.htm
In the text, the author, Ken Stewart, writes:
"You will eventually hear some old timer talk about the old days and
Carbona. Carbona was a dry cleaning product that contained
carbontetrachloride. Carbon tet in large quantities or in low exposure
over long periods of time is liver toxic. You cannot get it anymore
unless you are a chemist. It was a nice solvent because it was not
flammable. Carbona was replaced as a watermark fluid for a number of
years by benzene. You can’t get benzene anymore because it can cause
leukemia after long periods of exposure. (You get exposed to benzene
in small quantities every time you pump gasoline unless it has been
removed from that recently.) It is also not good for your health if
you breathe a lot of it over a long time. What this is leading to is
that all solvents are toxic if you breathe enough of them. Use
ventilation if you do more than a couple of stamps. It is your health
that you will wreck if you are stupid."
On searching "Carbon tetrachloride formula" I discovered these
warnings at http://www.ilpi.com/msds/ref/ccl4.html :
"If you are actually using carbon tetrachloride in your workplace,
definitely have an MSDS on hand and take every precaution you can to
eliminate and/or minimize its use. If you must use it, use appropriate
personal protective equipment (PPE) and try to confine the material to
a fume hood if possible."
and
"Carbon tetrachloride was widely used as an industrial solvent before
its health hazards were well-known. It is sometimes used as an
intermediate in the manufacture of other chemicals, and it has a
terrific degreasing ability. This latter property also resulted in its
use by the dry cleaning industry in the 20th century, but this
practice has long been abandoned."
Searching "buy benzene", I found a link to a site called ChemConnect
http://www.chemconnect.com/ stating they connect buyers and sellers
of chemicals worldwide.
Please, if you do find either of these cleaning agents (or the one for
which you asked) be very, very careful. If you find this
clarification encompasses your answer, please post so here and I will
repost this as an answer and claim the fee.

I do not have the name of the manufacturer. The company sent me these
notes and stamps gave me the instruction on the alkaline solution to
clean them. It's Skyway Inc out of Geneva, Switzerland. I tried to cal
them but to no avail.
It's a pH 8 to 8.5 mixture of Calcium Chloride saturated solution and
Sodium Carbonate saturated solution. That is just my guess, it may not
be the right combo though.....
thanks,
