Dishwashing salt is a special class of granulation, crystalline sodium chloride intended to regenerate water-softening circuits from household or industrial dishwasher. Similar to water-softening salts, dishwashing salts regenerate ion exchange resins, secrete calcium and magnesium ions inside them that characterize hard water. Salt water salt grains larger than table salt. The size of the granule ensures that the salt dissolves slowly, and that fine particles do not block the softener unit.
In some countries, especially in Europe, dishwashers include built-in water softeners that remove calcium and magnesium ions from water. Dishwashing salt, which is a coarse sodium chloride (table salt), is used to regenerate resins in the ion exchange system present in them. Coarse grains prevent it from clogging the softening unit. Unlike certain salt types used for culinary purposes, it does not contain any additional anticaking agents or magnesium salts. The presence of magnesium salts will defeat the purpose of removing magnesium from water softeners. An anticaking agent may cause a blockage or may contain magnesium. Table salt may contain additional iodine in the form of sodium iodide or potassium iodide. This compound will not affect the ion exchange system, but adding table salt to the dishwasher dishwasher unit may damage it.
If the dishwasher has a built-in water softener there will be a special compartment inside the dishwasher where salt will be added when needed. The salt compartment is separate from the detergent compartment, and is generally located at the bottom of the wash cabinet (this is under the bottom basket). In most dishwashers, the automatic sensing system will notify the user when more dishwashing salts are needed.
If the dishwasher has run out of salt that regenerates ion-exchange resins that soften water, and the "hard" water supply, lime deposits can appear on all items, but especially in the glass.
