Rinse aid
Rinse aid is a liquid for the dishwasher that improves the drying of dishes . It contains non-ionic surfactants , which reduce the surface tension of the water so that it can run off without droplets, as well as organic acids such as citric or lactic acid to form complexes of calcium and magnesium ions ( hardness builders ) and to neutralize alkali residues, as well as solvents, preservatives , solubilizers and possibly fragrances or bitter substances.
The dishwasher dispenses a few milliliters of rinse aid into the last wash cycle. Therefore, the final rinse cycle is also known as rinse cycle called.
Dishwashers usually allow the amount of rinse aid to be set in the wash cycle. On the one hand, excessively high doses of rinse aid can lead to streaking or traces of smell on the items to be washed, and on the other hand, lime stains can increasingly appear on the items due to insufficient rinse aid delivery.
