removing rust from stamps
George Politis
Does anyone have any details on how to do it?
Would bleaching work?

Hi George!
I've heard of collectors using "Milton" tabs... not sure whether for
general cleaning or rust removal though...
cheers

Go to http://www.west.net/~lmevans/apscom/pcpm.htm. This is the home page for
the APS Committee on Preservation and Care of Philatelic Materials. Look in
subsidary page 9, Wet Cleaning of Stamps and Covers, for their comments on
"Tropical stain". I believe that is the same thing ou are refering to.

Some years ago I tried this on some common old Mozambique Co stamps. I
used a dilute solution of a liquid bleaching intended for cloths washing
(I cannot remember the proportion of bleach to water but it seemed
pretty small) and immersed that stamps for a while. It was fairly
successful in removing the rust spots but and it did not destroy the
structure of the paper. It also whitened the paper and brightened the
colors. However, the paper appears much whiter than that of other clean
copies of the same stamps and the colors much brighter and the bleached
stamps look somewhat different. For these reasons I would not consider
displaying them and have stopped doing this. Besides, your collection
also ends up smelling of chlorine.

Considering also that some of the Portuguese colonies have reprints
that are on brighter paper and brighter colors this would definitely
cause a problem! :)

It's my understanding that foxing is an organic growth,
and will continue to spread unless treated. Hydrogen peroxide
seems to be the bleach of choice. I've never had much success
with using it to actually remove the foxed spots, but it
apparently does kill the causative agent.
Maybe more extensive use of the peroxide would remove the
spots. As with all experimental techniques, try it on
cheap or damaged stamps first!

1902-1903 pictorials that are perfect except for a rust spot from a paper
clip on the front. I remember hearing about a product specifiaclly sold
to remove rust (not necessairly "Foxing" or organics) from stamps. I
can't remember what it was though. I guess I should have bought it at
the time. Any help?

remove foxing. Whereas they suggest soaking the stamp for one minute
in the solution, I would suggest less time. Watch the stamp every
instant it's in the solution. When the stain is removed to your
satisfaction, remove the stamp and immerse in a fresh water bath to
remove as much of the chlorine as possible. The chlorine that remains
in the paper will deteriorate the paper over time.
For grins I submitted a few stamps so treated to APEX for examination,
most of them were returned with a "bleached" notation on the
certificate.

Are you referring to Lindner's A & B solutions? I bought them to clean up some
bargain basement foxed stamps but haven't worked with them yet. I believe they
use potassium permanganate which is nothing to play around with. I am told it
is a dramatic process until the final solution is applied. Lindner has a bunch
of chemicals for removing stuck stamps and hinge remnants. Better living
through chemistry but keep out of the reach of kids.

Personally, I use chemical solutions, made for me by my chemist, similar to
those sold, very expensive, by Lindner :
- a 3% solution of potassium permanganate, for 2-3 minutes (no more, it would
"burn" the stamp) in a saucer. Cover the stamp : it will turn all purple, and
the foxing black... don't be frightened... - a % solution of citric acid, for
10 minutes in a cup : the stamps turns back all clear, taking the foxing
away. - Rinse in clear running water, for 5-10 minutes, to take away the
acid.
It is a very efficient process, and normally it works in one time. If the
foxing is too important, you may use it a second time. Better 2 short baths,
than 1 long... ;-)
Some fragile colors (anilin colors especially) sometimes can't stand that
treatment , and disappear, but it works wonderfully on engraved stamps, and
whitens the paper...
You can treat 2 or 3 stamps at a time, but not more.
