Hints & tips: If your grinder becomes difficult to grind, particularly on a fine setting, trying clearing the mechanism by loosening the knob underneath the mill to the coarsest setting and twist the top. This will free any large salt crystals that may have become lodged. Retighten the knob to the desired setting but be sure to never fully tighten the knob. Clean grinders with a damp cloth, do not submerge in water. Disclaimer: product comes unfilled.
