Abstract

Die Erfindung betrifft ein Verfahren zum Flüssigreinigen eines Gegenstandes mit einer reinigungsaktiven Flüssigkeit, die zwischen 99 und 65 Gew.% Wasser und wenigstens eine organische Komponente mit Molekülen mit lipophilen und hydrophilen Gruppen enthält, wobei die Art und Konzentration der in der reinigungsaktiven Flüssigkeit enthaltenen organischen Komponente derart ist, daß die organische Komponente mit dem Wasser ein Azeotrop und bei der bei der Flüssigreinigung herrschenden Temperatur eine Mischungslücke bildet, wobei die reinigungsaktive Flüssigkeit während der Reinigung durch mechanische Agitation im Zustand einer Emulsion gehalten wird.The invention relates to a method for liquid cleaning an object with a active cleaning liquid containing between 99 and 65 wt.% water and at least one contains organic component with molecules with lipophilic and hydrophilic groups, the type and concentration of those contained in the cleaning active liquid organic component is such that the organic component with the water Azeotropic and a mixture gap at the temperature prevailing in liquid cleaning forms, the cleaning active liquid during cleaning by mechanical Agitation is kept in the state of an emulsion.
