Claims19
A method for washing or cleaning stains comprising a step of contacting a fabric comprising stains with washing or cleaning agents having a compound of general formula (I),
- in which A represents —Q—(CH2)n—Q, —(CH2)m—Q—(CH2)p— or
- Q represents O, N(R5) or N+H(R5) X−, R1, R2, R3, R4 and R5 represent, independently of one another, hydrogen or a straight-chain or branched unsubstituted alkyl group having 1 to 4 C atoms, X− represents a charge-balancing anion, and n represents a number from 1 to 10, and m and p represent, independently of one another, numbers from 0 to 7.
