Definitions

  • the commercially available powdery alkaline or acidic dishwashing, cleaning or rinsing agents are not or only insufficiently suitable for cleaning the so-called "problem areas" of the dishwashers which are at risk of contamination, since they are metered into and dissolved in the cleaning or rinsing cycle of the dishwashers can be, but the do not touch dirty areas at all or touch them too briefly. For this reason, for a long time it was only necessary to manually clean such zones.
  • the detergents used for cleaning dishes are unsuitable for such cleaning because they attack the skin too strongly.
  • Commercial cleaning agents for hard surfaces are also unsuitable for this special application, since they generally contain highly foaming surfactants, the residues of which in dishwashers can lead to various types of malfunctions.
