Method For Cleaning, Rust Removal And Watermark Clarifying

I'm looking for a simple method or methods for stamps over 50 years old
1] cleaning stamps
2] neutralising rust/foxing on stamps
3] cleaning back of stamp so that the watermark can be seen

Tony

Hi txstamp, no message with your reply OR do I have to do something to see it?

Hi there !

My comment is that this will be interesting to watch, as cleaning of stamps is a highly controversial, and complex subject.

Usually the answer is "don't", but foxing and similar issues are real problems that collectors run into, and what to do about these, once they've happened, are real problems, often without good solutions.

It really depends on what type of stamps - used or mint. If they are mint I would suggest leaving them alone. If they are used and have paper or hinge remnants on the back, soak them in warm water until the paper or hinge float off. Warm water generally will also clean a lot of other "crud" off of dirty stamps.

Tony - do be careful if soaking surface-printed GB Queen Victoria stamps, as it will damage the colours.

Good conservation stewardship is to use clear, clean, cool water. There are other things that can be done to make a used stamp look better/cleaner but this moves you into 'restoration' as opposed to 'conservation'. It is like getting a nice antique desk, refinishing it will make it look better but also makes permanent changes that can never be undone.

Don without creating a disagreement, why are you recommending cool water? I personally have found that cool water takes at least twice as long for the gum to release any envelope or package paper. The longer a stamp soaks in water the more likely I have found that colour will bleed, especially with red stamps or coloured envelopes. Anyway I'd appreciate hearing why. Thanks.

I agreed that warm water is faster, but warm water is more likely to cause fugitive inks (stamp or envelope) to go into solution. I also think that some folks will see 'warm water' and think hotter is better. Given that this is a large public community and very 'experience diverse' members, I think posting the safest method is the best approach.

We should also mention that folks should change their soak water often, allowing the solution to become filled with gum and other contaminates can coat the stamp with all kinds of crud.

Absolutely,
Flirt with warm water at your peril.

Not worth soaking any stamp on coloured paper, observe patience and seek another copy. You may cut around the stamp, 5mm border and scan
if you wish.

Neutralising foxing can be done, Google philately foxing and get advice from reputed Philatelic conservators.

Whilst a stamp is in cool water, can be the best time to see a watermark. Otherwise use Watermark fluid.
