A degreasing cleaner composition, which can efficiently remove oil from an oil-deposited material to be cleaned containing:
(A) 40 to 95% by weight based on total composition weight of at least one alcoholic compound selected from the group consisting of (a) a water-soluble polyol having 4 to 10 carbon atoms and at least two hydroxyl groups, (b) a water-soluble monoalkyl ether compound in which one hydrogen atom of the hydroxyl groups of the (a) polyol having 4 to 10 carbon atoms is substituted by an alkyl group having 1 to 5 carbon atoms, (c) a water-soluble monoacyl ether compound in which one hydroxyl group of the (a) polyol having 4 to 10 carbon atoms is substituted by an acyl group having 1 to 5 carbon atoms, and (d) 4-methyl-4-hydroxy-2-pentanone, and
(B) 5 to 60% by weight based on total composition weight of water.
