Natural and synthetic rubber and plastic deteriorate continuously.
Vinyl degradation doll.
Degradation during service life or after careless disposal is a chemical change that drastically reduces the average molecular weight of the polyvinyl chloride polymer.
It is therefore important for custodians of collections to be aware that by properly controlling the agents of deterioration the lifetime of these materials can be extended.
Including the eyes putty.
The trick is to clean off the coating.

Exposure has also been associated with brain tumors.
All of us humans leave behind traces of our own sweat and oil when we play with a doll for any length of time.
Since the mechanical integrity of a plastic depends on its high average molecular weight wear and tear inevitably weakens the material.

The vinyl used in dolls is a soft porous material.
Baby wipe your doll.
If the doll has just a light smattering of grime and looks a tad grungy you can wipe down its skin with baby wipes.

Pvc will probably last forever.
Now compare that to 10 plays of wax cilinder.

All polymers are subject to degradation based on environmental factors such as but not limited to heat uv light and moisture.
I ve seen this happen before to client s things especially old toys dolls and game console controllers.
I tried cleaning it with rubbing alcohol which didn t.
