I'm cleaning out my child's playroom and found a bunch of old Play-Doh containers. Some are still sealed. What's the shelf life?

The shelf life of Play-Doh varies according to whether it is sealed or unsealed:

Sealed Play-Doh containers, when properly stored in a cool, dry place, should be safe to use.

However, unsealed Play-Doh is more likely to dry out or become contaminated with dust, dirt, or mold if not stored properly. Examine unsealed Play-Doh for visible signs of mold or mildew, and discard if found.

If the Play-Doh has an unpleasant odor or feels crumbly and dry, it is likely past its prime and less enjoyable to use. You can try adding water and kneading it, but if it does not return to a good consistency, discard it.
