Removing ink from postage stamps, particularly postmarks, is a practice sometimes undertaken by collectors to clean or preserve the stamp itself. The method largely depends on the type of ink used and the stamp's age and condition.
One common approach, especially for non-permanent inks, involves using simple cleaning agents.
Methods for Removing Stamp Ink
When attempting to remove stamp ink, particularly postmarks, gentle methods are crucial to avoid damaging the stamp paper or its design.
Using Soap and Water
Based on common practice in philately and as supported by collecting information:
- Most non-staining inks can be washed off using mild soapy water.
This method is generally suitable for water-soluble inks often used in postmarks. The process typically involves:
- Preparing a shallow container with cool or lukewarm water.
- Adding a small amount of dish washing detergent mixed in the water to create a mild soapy solution.
- Gently placing the stamp into the solution, often face down, allowing it to soak briefly.
- Carefully removing the stamp and rinsing it with clean water.
- Placing the stamp face down on a clean paper towel and blotting gently, then allowing it to dry flat under a light weight between absorbent papers.
Caution: Avoid rubbing the stamp while it is wet, as this can easily damage the paper fibers and design.
Using Specialized Stamp Cleaners
For inks that are not water-soluble or for more delicate stamps, specialized Stamp Cleaners are available from philatelic suppliers. These products are formulated to dissolve ink residues with less risk to the stamp's integrity compared to harsh chemicals. Always follow the product instructions carefully and test on a less valuable stamp first.
Important Considerations
- Ink Type: The success of ink removal heavily depends on whether the ink is water-soluble or permanent.
- Stamp Value & Condition: Attempting to remove ink can potentially decrease a stamp's collector value, especially for rare or valuable items. Older stamps can be fragile and easily damaged by soaking or cleaning.
- Postmarks: Some collectors prefer to keep stamps with their original postmarks as they are part of the stamp's history and can add interest.
- Handling: Always use stamp tongs when handling stamps, particularly when wet.
While mild soapy water is effective for many common non-staining inks, success is not guaranteed for all ink types, and there is always a risk of damaging the stamp.
