Salt Grinder Stuck? How to Unstick It
A stuck salt grinder is almost always damp salt clumping the mechanism. Here's the two-minute rice-and-dry fix, and how to stop it seizing again.
PUBLISHED JUL 3, 2026
A salt grinder seizes for one reason far more than any other: damp salt has clumped around the mechanism. Salt pulls moisture from the air, sets like mortar, and locks the rotor. The fix is quick.
The two-minute fix
- Empty what pours out freely.
- Dry the mill open overnight so the moisture evaporates.
- Grind dry white rice through it — the rice scrubs the ceramic core and absorbs the damp residue.
- Brush and refill with dry, coarse salt.
If the top nut is what’s stuck rather than the mechanism, that’s usually salt in the thread — wrap it in a dry cloth for grip and work it gently (never pliers on wood). More in the not-working guide.
Stop it happening again
- Fill only dry, coarse salt — never damp or flaky finishing salt (see what to put in a salt grinder).
- Keep the mill off the stove’s steam path — humidity is the real culprit.
- Store it somewhere dry; our storage guide has the details.
A well-kept ceramic mill — like the ones in our wooden ranking — should almost never seize. If it’s still stuck after drying and the rice trick, the core may be worn out.
Frequently asked questions
Moisture. Damp or flaky salt, or a mill kept over steam, clumps and cements around the mechanism. Use dry coarse salt and keep the grinder away from the stove.
Empty it, let it dry overnight, then grind a spoonful of dry white rice through to scrub and absorb the residue. Brush out the mechanism and refill with dry salt.
That is usually salt in the thread. Wrap the nut in a dry cloth for grip and work it loose gently; avoid pliers, which crush a wooden top.
