Can I use Vaseline to soften polymer clay?

Polymer clay is a versatile and popular medium used by artists and crafters to create a wide range of projects. Its pliability and ability to hold intricate details make it a favorite for sculpting and crafting. If you’re working with polymer clay that has become slightly firm or hard, you might have heard about using Vaseline as a potential softening agent. In this article, we’ll explore the concept of using Vaseline to soften polymer clay and provide insights into its effectiveness and potential considerations.

The Nature of Polymer Clay

Polymer clay is composed of polymer particles, plasticizers, and pigments. The plasticizers in the clay give it its flexibility and malleability. When polymer clay becomes firm or hard, it may be due to factors such as air exposure, improper storage, or the passage of time.

Using Vaseline to Soften Polymer Clay

Some crafters have experimented with using Vaseline (petroleum jelly) as a way to soften polymer clay. The idea is that applying a small amount of Vaseline to the clay and kneading it can help reintroduce moisture and flexibility, making the clay easier to work with.

Potential Benefits:

  • Increased Pliability: Vaseline may help soften the clay, making it easier to knead, shape, and sculpt.
  • Restoration of Texture: The added moisture from Vaseline might help restore the smooth texture of the clay, especially if it has become slightly dry or crumbly.


  • Residue: Vaseline can leave a residue on the clay’s surface, which may affect the finish and appearance of your final project.
  • Long-Term Effects: The long-term impact of using Vaseline on polymer clay is not well-documented. Over time, the Vaseline could potentially interact with the plasticizers and affect the clay’s properties or durability.
  • Alternative Solutions: While some crafters have had success using Vaseline, there are alternative methods and products specifically designed for softening polymer clay, such as clay softeners or conditioning oils.

Best Practices

If you decide to experiment with using Vaseline to soften polymer clay, here are some best practices to keep in mind:

  • Use a minimal amount of Vaseline to avoid excessive residue on the clay.
  • Knead the clay thoroughly after applying the Vaseline to distribute it evenly and ensure consistent softening.
  • Consider testing the technique on a small piece of clay before using it on a larger project to gauge the results.
  • Be cautious and aware of any changes in the clay’s texture, pliability, or appearance over time.


While using Vaseline to soften polymer clay may offer a temporary solution for firm or hard clay, it’s important to approach this technique with caution. Consider the potential effects on the clay’s properties and appearance, and be mindful of alternative methods and products specifically designed for conditioning and softening polymer clay. As with any crafting technique, experimentation and careful observation will help you determine the best approach for achieving the desired results in your projects.
