How to Remove Stamps from Envelopes Without Damaging Them
Soaking stamps off paper is simple when you know the steps. Here is how to remove used stamps safely, and when you should leave them on the envelope.
Many collections begin with a stack of old envelopes. Removing those stamps the right way protects their condition and their value. A torn corner or a thinned back can turn a nice stamp into a space filler, so it pays to be patient.
First, Decide Whether to Remove It at All
Not every stamp should come off its envelope. Leave stamps on the paper if the envelope is a first day cover, has an interesting postmark or cachet, or shows unusual postal history. In those cases, the whole envelope is the collectible. (Learn more in our guide, What Are First Day Covers and Why Do Collectors Love Them?.)
Never soak unused stamps with original gum. Water removes the gum, and collectors pay a premium for it.
What You Will Need
- A shallow bowl or dish of lukewarm water
- Stamp tongs (fingers leave oils that can stain)
- Paper towels or blotting paper
- A heavy book for pressing
Step-by-Step: Soaking Stamps
1. Trim the Envelope
Cut around each stamp, leaving a small margin of paper. Do not cut too close, or you risk clipping the perforations.
2. Sort Before Soaking
Separate stamps on colored or heavily printed envelopes and soak them on their own. Dyes can bleed and stain every stamp in the bowl.
3. Soak Face-Up
Float the stamps face-up in lukewarm water. Most will begin to release within 10 to 20 minutes. Let the water do the work and never pull a stamp off the paper.
4. Lift Gently with Tongs
Once a stamp slides away freely, lift it out with tongs. If any gum remains on the back, give it a quick rinse in clean water.
5. Dry Face-Down
Lay the stamps face-down on a paper towel. After they are damp-dry, place them between clean paper towels under a heavy book overnight. This keeps them flat and prevents curling.
A Note on Self-Adhesive Stamps
Modern self-adhesive stamps can be tricky. Many do not release cleanly in water and can be damaged by soaking. When in doubt, leave them on a neatly trimmed piece of envelope. Plenty of collectors mount them that way.
Common Mistakes to Avoid
- Using hot water, which can fade colors
- Peeling stamps off before they float free
- Drying stamps face-up, which can cause them to stick to the towel
- Handling wet stamps with your fingers
