To Wash Or Not To Wash, That Is The Question.

I collect 19th century U.S. issues. I have a large stash of used stamps to sort through, grade, inventory and plate. But one thing I am unsure about is washing the stamps.

A large number of my used stamps are dirty. The grime makes the image less attractive, mutes color, and makes the stamps harder to plate.

So...my question, focusing on older 19th century stamps, would you you recommend washing the stamps, or is the danger of damage or loss of design too great? Is washing effective.

If washing is recommended, what is the best option to be as gentle as possible?

Thanks to anyone who replies. Figured this was the best place to look for advice.

Each stamp must be decided by a experience collector or dealer . There is no one answer to a lot containing many stamps . Cheaper stamps under ten dollars I would soak in water with a little soap for a few minutes . More expensive stamps it is by the stamp to judge .

I've liked the results every time I have soaked stamps to clean them. I've saved some stamps I thought were junk and I have discovered repairs to stamps that way too! I usually soak to remove old hinges.

A picture or two would help give more solid advice.

I once washed a Black Jack stamp that had several heavy hinges on the back. Since it was used, I wasn't concerned about the gum. When I washed it, the stamp fell apart. Apparently, those hinges had been holding multiple pieces together.

alub. I've had something similar happen. If we are talking blackjack value level... I soak one at a time in a small clear cup so I can watch the action and hope to not be disappointed! I have discovered some pinholes this way too. rogdcam, I have a photo somewhere of soaking better stamps, but buried in the digital junk drawer. I'll be on the hunt!

@rogdcam, I'll take a couple images and post, but to be even more specific, I am working to plate all my US #9s and work toward a full Plate 1L, so I am primarily focusing on my 1c 1851 Franklins. The run the gambit from dingy to plain dirty. None of them are on a cover or a piece. I figured if I cleaned them up a bit, I may be able to get a clearer look at the original design, making it easier to plate.

@rogdcam, here's an example of a US #9 that I think would be worth cleaning up a bit. This one has a bit of grime all along the edges. Is it worth washing to clean up and bring out some more clarity with the ornaments? Sorry for the delay in posting.
