A hard surface liquid cleaner composition containing (a) a polyalkylene glycol monoalkyl ether, (b) amine oxide, (c) at least one type selected from a group consisting of C8-18 aliphatic acids and salts thereof in the amount of 0.001-15% by mass, and water. The mass ratio of (c)/((b)+(c)) is 0.001/1 to 1/1. 60-100% by mass of the (a) component is a dipropylene glycol (C4-8 alkyl group) monoalkyl ether. The pH at 25 DEG C is 8-14. This hard surface liquid cleaner composition not only exhibits strong cleaning power against cooking oil buildup, but also remains in a uniform liquid state with no turbidity or separation, and furthermore, has the effect of exhibiting excellent wiping and rinsing properties of a cleaner.
