Signs iodized salt has gone bad
- Caking or damp clumps from kitchen humidity.
- A musty smell from absorbed odours.
- Faded iodine benefit after long open storage.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store iodized salt
The salt itself never spoils, but the added iodine slowly off-gasses in light and in an open container, so the table-salt benefit fades over time. Keep the lid closed and the box out of direct light to hold onto the iodine longer.
