Understanding Vinyl Doll Disease

One doll’s decay can quietly damage the rest. Here’s what to look for and how to stop it.

‍

Not all damage is visible at first — and in the world of vintage dolls, one of the more distressing problems we encounter is something often called "vinyl disease", or more accurately, vinyl degradation.

It’s sometimes referred to as the “cancer of doll collections”, and for good reason. Left unchecked, it can quietly spread from one doll to another, causing sticky residue, chemical leaching, and irreversible damage — not just to the affected doll, but to any that come into contact with it.

At My Doll Cottage, Mum has seen it first hand sadly getting rid of many beautiful dolls. Luckily she detected this prior to them entering the museum. There is one lucky survivor why damage was just to her hands and at this stage has not spread further. Mums looking for space to display her in the museum seperately under her own glass dome.

 Here’s what you need to know to spot, prevent, and manage vinyl deterioration in your own collection.

What Is Vinyl Disease?

"Vinyl disease" isn’t an official scientific term, but it's widely used by collectors to describe the break down of poly vinyl chloride (PVC) in vintage dolls. It’s most commonly seen in dolls made between the 1950s and 1980s, though it can affect others depending on material blends.

Over time, the plasticisers (the chemicals that keep vinyl soft and flexible) begin to leach out. This causes:

• A sticky or greasy surface
• Strong chemical or vinegar-like smells
• Discolouration (often grey, green, or mottled patches)
• Bleeding or melting marks on nearby surfaces or dolls

In severe cases, the vinyl becomes brittle, distorts, or oozes, leaving damage on anything touching it.

Can It Spread?

Yes —that’s one of the most concerning parts. Vinyl disease isn’t infectious like a germ, but the off-gassed chemicals released from the degrading vinyl can damage other dolls, especially those stored closely together or touching.

It can also affect:

• Doll clothing (especially synthetics and lace)
• Painted features
• Display cabinets and plastic shelving

This is why we always recommend isolating any affected dolls immediately — just like Mum did when she noticed signs on one of hers.

What Causes It?

Several things can speed up vinyl degradation:

• Heat and humidity
• Poor storage conditions (especially sealed plastic tubs)
• Sunlight or UV exposure
• Age and chemical makeup of the original vinyl

Some dolls were made with materials that were less stable over time, especially early soft vinyl blends or cheap factory batches made in warmer countries.

How to Spot It Early

Check your dolls regularly for:

• Sticky arms or legs
• “Sweaty” or greasy surfaces
• A sour or chemical smell
• Cloudy, rough, or cracked skin (Check her wrists in the close up photo below)
• Any residue left on nearby dolls or shelf surfaces

These are all signs that vinyl disease may be beginning.

What to Do If You Find It

1. Isolate the doll immediately
   
    
   • Keep it away from other dolls
    
   • Wrap it in acid-free paper or cotton cloth (not plastic!)
 
2. Do not store in sealed containers
   
    
   • Let the doll breathe to reduce off-gassing
    
   • Avoid hot or humid spaces
 
3. Use caution with cleaning
   
    
   • Some recommend wiping with 70% isopropyl alcohol, but this is only a temporary      fix and may worsen cracking
    
   • If sentimental or valuable, consider professional conservation advice
 
4. Decide if the doll can be displayed separately
   
    
   • Some collectors keep affected dolls in glass domes or isolated units
    
   • Others retire or part with the doll if it’s too far gone

Mum’s Experience

Due to mums attention to detail and obsession with the restoration and cleanliness of all dolls before they enter the museum she was able to catch the dolls that have had this disease. Mum said you can't not smell the odour with vinyl disease, it's just a matter of understanding what the smell is about. Thankfully, she was able to save this little HP pedigree girl. The disease hasn't spread and mums just thinking of ways to safely put her on display that keeps the collection safe and doesn't take up oo much space.

Prevention Tips for Collectors

• Store dolls with airflow – avoid sealing them in plastic tubs
• Keep out of heat and sunlight – temperature stability is key
• Use acid-free tissue between dolls when storing
• Regularly inspect your collection — especially dolls from the 60s–80s
• Display dolls with slight space between them to prevent chemical contact

Final Thoughts

Vinyl disease is one of those hidden risks that many collectors don’t learn about until it’s too late. But with care, regular checks, and gentle storage, you can keep your collection safe for years to come.

At MyDoll Cottage, we continue to share what we learn as we catalogue and protect our family’s collection — so others can do the same with theirs.
