How to Protect Stamps from Damage
Stamps are damaged mainly by damp, light, heat, careless handling and well-meaning "improvement". To protect them, keep them cool, dry and out of strong light, handle them only with tongs, store them in acid-free materials, and never clean or alter them. Understanding each kind of damage, and the simple step that prevents it, is the surest way to keep a collection in fine condition, and to protect its value.

Damage, cause and prevention
| Damage | Cause | Prevention |
|---|---|---|
| Foxing, sticking | Damp | Keep cool and dry |
| Fading | Light, sunlight | Store out of strong light |
| Curling, dried gum | Heat | Steady, moderate temperature |
| Toning | Acidic materials | Acid-free, archival storage |
| Marks, thins | Careless handling | Use tongs, handle gently |
| Lost value | Cleaning, "improving" | Leave stamps as they are |
The kinds of damage, and how to prevent each
Most harm to stamps falls into a few kinds, and each has a simple safeguard. None of the safeguards is difficult or costly.
Know the threat, apply the remedy, and a collection stays sound for a lifetime.
- Damp and foxing. Moisture is the greatest enemy. It causes "foxing", the small brown spots seen on old paper, sticks stamps to pages or each other, and disturbs gum. Keep stamps cool and dry, and never store them in a damp loft, garage or cellar.
- Light and fading. Strong light, above all sunlight, fades the colours that give a stamp its appeal, and faded colour cannot be restored. Store and display stamps away from direct light.
- Heat and dryness. Heat and temperature swings curl stamps and dry out gum. A steady, moderate temperature keeps stamps flat and sound.
- Toning. Acidic paper and poor materials cause "toning", a yellowing or browning of the stamp over time. Acid-free, archival storage prevents it, as our guide to storing stamps explains.
- Handling damage. Fingers, bending and ordinary tweezers all mark or thin stamps. Always use proper stamp tongs and handle gently, as our guide to handling stamps describes.
- Pests. In poor storage, damp and insects can attack paper and gum. Clean, dry, sealed storage keeps pests away.
The damage you do yourself
It is worth naming the damage that comes not from neglect but from good intentions. Trying to clean a stamp, peel it from paper while dry, flatten a crease, or "improve" its appearance almost always does harm and reduces value, often severely. The single best thing you can do for a stamp is to leave it as it is. Our guide on whether you should clean stamps explains why, and our guide to removing stamps from paper shows the only safe way to take a stamp off its paper.
Protecting value, not just stamps
Condition is value
Behind all of this lies a simple truth: protecting a stamp's condition is protecting its value. A stamp's worth depends heavily on its state, so damp, fading, toning or careless handling do not just spoil a stamp, they cost money, as our guide to what affects a stamp's value explains. The good news is that prevention is easy and cheap: a cool, dry, dark place, acid-free materials, tongs, and the discipline of leaving stamps untouched. These few habits preserve both the stamps and their value for a lifetime.
A simple protection checklist
- Keep the collection cool, dry and out of strong light.
- Store it in acid-free, stamp-safe materials.
- Handle every stamp with tongs, never fingers.
- Keep stamps flat and supported.
- Check now and then for any sign of damp.
- Never clean or alter a stamp. Our guide to storing stamps sets out the practical storage that achieves this.
Frequently asked questions
Mainly damp (causing foxing and sticking), strong light (fading), heat (curling and dried gum), acidic materials (toning), careless handling (marks and thins), and cleaning or "improving", which reduces value.
Keep them cool, dry and out of strong light, store them in acid-free materials, handle them only with tongs, keep them flat, and never clean or alter them.
Foxing is the small brown spots that appear on paper kept in damp conditions. It is best prevented by keeping stamps cool and dry, since it cannot be safely removed.
Yes. A stamp's value depends heavily on its condition, so damp, fading, toning and careless handling all reduce value as well as spoiling the stamp.
