Improved microemulsions having a lower level of solvent, a lower level of oil, a more robust formulation and/or exhibiting equivalent if not better performance on fatty soils can be obtained by simultaneous selection of specific surfactants, specific oils and specific solvents. When all three of these components are selected in the manner described herein, a synergistic benefit is attained. The present invention provides a liquid, aqueous cleaning composition in the form of a stable emulsion having a dispersed phase diameter of 10-100 nanometres comprising:
