And in case you're wondering where the water comes from in rock salt, remember that sodium chloride is a powerful desiccant, it'll literally remove water from the air and turn it into salt water -- which is also why it's used as a food preservative, because it very thoroughly dries it (and any bacteria it might have, too)

This basically does happen in places with high humidity. It doesn't become "full" of water, but the salt clumps together enough to become impossible to shake out of the container. One remedy is to mix the salt with dry rice, which is either more of a desiccant than salt or has a mechanical effect that breaks up the clumps.

just like glitter clumping, it’s a common stripper problem.
Well that’s what my Nan used to say

There is a humidity difference between your kitchen and an underground mine.

The top of the shaker is often covered with water droplets where I live due to the salt residue collecting moisture from the extremely humid air.

Where would this be? That sounds like variations in temperature are causing condensation. I have lived on a literal island in the ocean, 500 meters from the pounding waves, and have had my salt clump a bit, but never dissolve itself into salt water in the container, even though dew and condensation was on everything at least some part of almost every day.

Many restaurants put rice in the shaker to help break up clumps that form when it a absorbs moisture.
