1. A form of granulated sodium chloride used to soften the water in dishwashers.
   • 1997, Nicola Bates, Paediatric toxicology: handbook of poisoning in children, page 132:

     Dishwasher salt is sodium chloride (salt, see page 326) and is used to prevent scaling of the machine, not in the dishwashing process.

   • 2007, Nigel Saunders, Exploring Chemical Reactions, page 27:

     Very pure sodium chloride is also used as dishwasher salt. This keeps the built-in water softener working and stops the plates from getting white deposits on them.

   • 2011, Nduka Okafor, Environmental Microbiology of Aquatic and Waste Systems, page 232:

     This is the method of operation used in dishwashers that require the use of “dishwasher salt.” The salt is used to recharge an ion exchange resin, which itself is used to soften the water so that limescale deposits are not left on the cooking and eating utensils being washed.
