Dishwasher salt is a particular grade of granulated, crystalline sodium chloride intended for use in dishwashers. Like water softener salt. dishwasher salt regenerates ion exchange resins, and removes the calcium and magnesium ions that characterize hard water. Dishwater salt granules are larger than those of table salt; the granule size ensures that the salt dissolves slowly, and that fine particles do not block the softener unit.
Dishwasher salt is 95% sodium chloride; an anticaking agent (e.g. sodium ferrocyanide or potassium ferrocyanide) constitutes the remaining 5%.
Alternatives are also being developed for dishwasher salt. TU Eindhoven developed a water softening polymer as an alternative.

“I’m not a dishwasher anymore. But I’m still from Sangamon Street.”

“Well, I know you haven’t had much experience writing and none at all in pictures. But I’ve heard about you. It all sounded like you’re just the man I wanted for a story about the Navy. I don’t want a story just about ships and planes. I want a story about the officers.... I want this story from a pen dipped in salt water not dry martinis. Do you know what I mean?”
—Frank Fenton, William Wister Haines, co-scenarist, and John Ford. John Dodge (Ward Bond)
