Liquid cleaning compositions are disclosed which comprise a nonionic surfactant, a polymer and an amphoteric surfactant according to the formula: R1R2R3N or R1R2R3N+X wherein the substituent R1 is a substituted or unsubstituted, saturated or unsaturated, linear or branched hydrocarbon chain having from 6 to 22 carbon atoms, wherein the substituents R2 and R3 each independently are a C1 to C6 alkyl carboxylic acid group, which may be the same or different, and wherein X is hydrogen. These compositions have the advantage to exhibit improved physical stability.
