It’s very simple to store air dry clay. Once you open a packet of air-dry clay, like the Crayola brand that comes in a tub, it’s important to remember that this material naturally hardens when exposed to air. That means you need to protect it from unwanted air contact at all times to keep it soft and workable.
Here’s how you can best store your air dry clay.
Storing Clay
While you’re crafting, only take out the amount of clay you need and immediately wrap or cover the rest. Leaving the clay uncovered, even for a short time, can cause the edges to dry out and become tough to mold. If you notice that happening, you can try kneading in a tiny bit of water to soften it again, but prevention is always easier.
When you’re done working on your project, make sure to store any leftover clay properly. Wrap it tightly in plastic wrap (like cling film or Saran Wrap), pressing out as much air as possible. Then place the wrapped clay in an airtight container, a ziplock, or a resealable plastic bag for extra protection.
If you live in a dry climate, you can also add a slightly damp paper towel inside the bag or container to help maintain moisture. Stored this way, your air dry clay will stay soft and ready for your next creative session.

How long can you store air dry clay?
I’ve stored air-dry clay this way for long periods —up to several months in some cases and up to a couple of years. And it has stayed perfectly usable. The key is keeping it well-sealed and away from heat or direct sunlight. If the clay feels a little stiff after long storage, I simply knead in a small amount of water, and it softens right back up.
