  • the use of the care product according to the invention in a water-soluble envelope has the advantage that, in contrast to the usual bottles, which are closed with a wax seal, which only dissolves at high water temperatures, the pre-proportioned dosage units are already available at lower temperatures and therefore possibly earlier in the Sequence during the cleaning process or during the rinsing cycle.
  • a dosing unit that is pre-proportioned in this way also generally takes up less space than one of the commercially available bottles that have been used up to now, which either have to be hung in the machine or placed in the cutlery basket. It can also be placed anywhere inside the dishwasher.
  • a dishwashing method in particular an automatic dishwashing method, in which a care product according to the invention is used is disclosed.
  • a method for cleaning dishes in a dishwasher in which the care product according to the invention is metered into the interior of a dishwasher while running through a dishwashing program before the start of the main wash cycle or during the course of the main wash cycle, is also disclosed.
  • the agent according to the invention can be dosed or introduced into the interior of the dishwasher manually.
  • the filter (in two parts) was weighed dry.
  • the beef tallow and pasta sauce were placed directly in the dishwasher and a commercial dishwashing detergent (Somat 7, Henkel, DE) was placed in the dispenser. Then a cycle with the intensive 70°C program was run. The filter was then removed, the remaining water was allowed to drip off for 30 minutes and the amount of fat built up was determined using a scale.
