Definitions

  • the invention is directed to a cleaning method comprising a alkaline and an acidic purification step and one or more others alkaline and / or acidic cleaning steps, in particular for mechanical Dishwashing in commercial dishwashers, in particular Starch deposits are excellently removable.
  • a base based alkaline solution an aqueous alkali hydroxide solution is presented.
  • To this basic solution can then be added as needed one or more additives.
  • the Dosage of these additives is usually proportional to the addition of the base liquor or timed. If desired, the dosage of the additives can also depending on the timing of the laundry through the machine befördemden Chain done.
  • a dosage of additives or the Increasing the additive concentration due to the detection of the share Additive in the base liquor via sensory detection of a tracer in the Additive is included, possible.
  • a cleaning agent Low alkaline cleaner especially based on phosphate or Nitrilotriacetic acid or its salts (NTA)
  • NTA Nitrilotriacetic acid or its salts
  • the object of the present invention was to provide a solution create when cleaning in commercial cleaning machines or even in Household machines of the formation of a starch coating on the Wash laundry sustainably prevented and / or degrades existing starch coverings, or and not necessarily the use of enzymes, bleaches, or extremely high alkalinity.
  • the subject of the present invention is a A cleaning method according to claim 1 comprising an alkaline and an acidic Purification step and one or more other alkaline and / or acidic Cleaning steps, in particular for machine dishwashing in commercial dishwashers.
