PROBLEM TO BE SOLVED: To obtain a liquid detergent composition which is suitable for cleaning dust-free garments by controlling the content of an inorganic cation in a composition mainly comprising nonionic surfactants and the pH at a specified concentration, each to a specified value or lower. SOLUTION: The content of an inorganic cation in a composition mainly comprising nonionic surfactants represented by formulas I and II is controlled to 500 ppm or lower; and the pH, when the composition diluted to a concentration of 0.2%, is controlled to 8-10. In the formulas, R1 and R3 are each an 8-20C prim- or sec-alkyl or alkenyl group; R2 and R4 are each an added ethylene oxide unit; n is 5-6 provided, when the average number of moles of an added nonionic surfactant in a largest amount is n1MAX and the total amount of nonionic surfactants of which the average number of moles is in the range of from n1MAX-2 to n1MAX+2 is Xi, Xi>=55 wt.%; R5 is an added propylene oxide unit; m1 is 5-20; and m2 is 1-4.
