  • Dishwashing detergents have many requirements to fulfill. They must thoroughly clean the dishes, have no harmful or potentially harmful substances in the wastewater, allow the draining and drying of the water from the dishes, and should not cause problems when operating the dishwasher. Finally, they should not lead to aesthetically undesirable consequences on the good to be cleaned. Especially in this context is the glass corrosion.
  • Glass corrosion is caused not only by mechanical effects, for example, by juxtaposition of glasses or mechanical contact of the glasses with parts of the dishwasher, but is mainly promoted by chemical influences.
  • certain ions can be released from the glass by repeated mechanical cleaning, adversely altering the optical and thus the aesthetic properties.
  • Glass corrosion has several effects. On the one hand, one can observe the formation of microscopically fine cracks, which are noticeable in the form of lines. On the other hand, in many cases one can observe a general cloudiness, for example a roughening, which makes the glass in question look unaesthetic. Overall, such effects are also subdivided into iridescent discoloration, scoring and surface and annular opacities.
