The use of diquaternary polysiloxanes in detergents for machine dishwashing leads to advantageous effects, especially when the diquaternary polysiloxanes are used in the clear rinsing cycle. Diquaternary polysiloxanes of formula (I) are preferably used in which: Z represents a quaternized nitrogen center; R' and R'', independent of one another, represent a C1-C4- alkyl radical or an aryl radical; M represents a bivalent hydrocarbon radical which has at least 4 carbon atoms, which preferably comprises at least one hydroxy group, and which can be interrupted by one or more oxygen atoms and/or groups of the type -C(O)-, -C(O)O- or -C(O)N-; n represents a number ranging from 1 to 201, and; X<-> represents an inorganic or organic anion. |
