Removing self-adhesive stamps from paper requires a different approach than traditional water-soluble gummed stamps, as their adhesive is designed to be permanent and resistant to water. The most effective method typically involves using a specific type of solvent.
The most reliable way to safely remove self-adhesive stamps from paper without causing significant damage to either the stamp or the paper is by carefully using a solvent designed to dissolve the stubborn adhesive.
Unlike older stamps that could simply be soaked in water, self-adhesive stamps utilize a strong, water-resistant glue. Attempting to peel them off dry will likely tear the stamp or the paper. Soaking them in water is generally ineffective and can damage the stamp's ink and the paper it's attached to.
Using a Solvent (Like Bestine) for Removal
A common and recommended method involves using a solvent like Bestine (Heptane solvent) or similar stamp-specific removers. These solvents work by dissolving the adhesive bond between the stamp and the paper.
Here's a step-by-step guide based on expert recommendations:
- Preparation: Work in a well-ventilated area. Place the paper with the stamp on a clean, protective surface. You'll need an eyedropper, the solvent (e.g., Bestine), and possibly some tweezers.
- Apply the Solvent: Use an eyedropper to "suck up" a small amount of Bestine and apply it, a few drops at a time, to the envelope side - as opposed to the stamp side - of the piece. Applying to the back allows the solvent to soak through the paper and reach the adhesive layer from behind.
- Apply Sparingly: Use it sparingly. You don't need to flood the paper. A few drops at a time are sufficient.
- Allow Soaking: Allow it to soak through the paper, which becomes translucent quickly. This translucency indicates the solvent is reaching and starting to work on the adhesive.
- Gentle Separation: Once the paper becomes translucent around the stamp and you can see the adhesive loosening, gently try to lift the stamp from a corner using tweezers or your fingers.
- Reapply if Needed: If the stamp doesn't lift easily, apply a few more drops of solvent to the back, targeting the areas that are still stuck. Be patient and avoid forcing it.
- Cleaning Up: Once the stamp is removed, there might be some residual adhesive on the stamp or the paper. Often, the solvent helps lift most of it. Place the removed stamp face down on a clean surface to allow the solvent to evaporate completely and the stamp to dry flat.
Why This Method Works
Solvents like Heptane are non-polar chemicals that effectively break down the non-polar polymer chains in the self-adhesive glue. Unlike water, which can damage the paper fibers and ink without affecting the adhesive, these solvents target the glue specifically, allowing for cleaner separation. They also evaporate relatively quickly, minimizing long-term exposure and potential damage once the stamp is removed.
Important Considerations
- Ventilation: Solvents produce fumes. Always work in a well-ventilated area, preferably outdoors or near an open window.
- Flammability: Solvents like Bestine are often flammable. Keep them away from open flames or sparks.
- Paper Type: While this method is generally safe, very thin or fragile paper might still be susceptible to damage. Test on a less valuable piece first if possible.
- Stamp Ink: Most modern stamp inks are resistant to these solvents, but exercise caution, especially with older or unusual stamps.
- Alternative Solvents: Other products marketed for stamp removal or art cleanup (check that they specify safe for paper/ink) might contain similar effective solvents. Always check product instructions.
Comparison: Self-Adhesive vs. Gummed Stamps
| Feature | Gummed Stamps | Self-Adhesive Stamps | Removal Method |
|---|---|---|---|
| Adhesive | Water-soluble gum | Strong, synthetic, water-resistant | Water soaking |
| Ease of Use | Requires moistening | Peel and stick | Easy |
| Removal | Relatively easy (soaking) | Difficult (requires solvent) | More complex |
| Damage Risk | Low (if done carefully) | Higher (peeling, improper solvent use) | Requires care/specific method |
By carefully applying a suitable solvent like Bestine to the back of the paper, you can successfully detach self-adhesive stamps for your collection while preserving their condition and the paper they were attached to.
