Subject: [pure-silver] Cleaning Brown Bottles
Someone gave me several nice old Kodak brown glass
bottles. One of
them was crudded up beyond use, but the others are almost
usable.
I say "almost" because there is some residue on the inside
that will
not come off with repeated hot water/soap/rise cycles. (I
believe
they may once have held D-76.) The bottle opening is,
perhaps
about 20mm but the bottle diameter is probably around
80mm. This
means it's kind of difficult to get into the bottle to
scrub it
out in any reasonable manner.
Any ideas out there of how to get the residue out of these
bottles
or should I just toss them into the garbage?

I already suggested BB shot.
FWIW, Kodak tray cleaner is a standard chromic acid
glass cleaner
Kodak TC-1
Water.............................1.0 liter
Potassium dichromate.............90.0 grams
Sulfuric acid, concentrated......90.0 ml
Use full strength. Swirl this around in the vessel, then
pour out and rinse well. The solution can be re-used many
times.
This is not strong enough to cause immediate burns but
should be kept off the hands.
Kodak TC-3 Tray and hand cleaner
Solution A
Water........................1.0 liter
Potassium permanganate.......2.0 grams
Sulfuric acid, concentrated..4.0 ml
Store solution in a stoppered glass bottle away from the
light.
Solution B
Water.........................1.0 liter
Sodium bisulfite.............30.0 grams
Sodium sulfite, desiccated...30.0 grams
The solutions A and B can be used for cleaning several
vessels but should be discarded after use.
An acid fixing bath may be used in place of Solution B
but it is important to wash thoroughly to eliminate hypo
from the tray or hands.
Cleaning Trays: To remove stains due to silver, silver
sulfide, and many dyes, pour a small quantity of Solution A
into the vessel and allow to remain for a few minutes; rinse
well and then replace with a similar volume of Solution B.
Agitate so as to clear the brown stain completely, they wash
thoroughly.
Cleaning Hands: to clean stains from the nails and skin
remove rings from the fingers and dip the hands in Solution
A contained in a glass or other suitable vessel, gently
rubbing the stained areas. Rinse briefly in running water
and immerse in Solution B to remove the brown color; then
wash thoroughly, preferably in warm water.
