Dishwasher salt, which is coarse-grained sodium chloride (table salt), is used to regenerate the resin in the built-in ion-exchange system. The coarse grains prevent it from clogging the softener unit. Unlike certain types of salt used for culinary purposes, it does not contain added anticaking agents or magnesium salts. The presence of magnesium salts will defeat the purpose of removing magnesium from the water softener. Anticaking agents may lead to clogging or may contain magnesium. Table salt may contain added iodine in the form of sodium iodide or potassium iodide. These compounds will not affect the ion-exchange system, but adding table salt to the dishwasher's water softening unit can damage it.
