To provide a cleaner composition that has excellent removing power of fine particles and can be reused after used for cleaning, and a cleaning method using the cleaner composition.SOLUTION: A cleaner composition contains a hydrocarbon solvent (A), a compound (C) of general formula (C-1), and water (W). The difference in boiling points between the hydrocarbon solvent (A) and the compound (C) is 30°C or lower. In the formula (C-1), R1 and R2 independently represent a C1 or 2 alkyl group or alkenyl group, X is a single bond or a C1 to 4 divalent aliphatic hydrocarbon group, where, the number of carbon atoms of R1, R2 and X is 4 or more.SELECTED DRAWING: None 【課題】微粒子の除去性に優れ、かつ、洗浄に用いた後に再利用が可能な洗浄剤組成物、及び当該洗浄剤組成物を用いた洗浄方法の提供。【解決手段】炭化水素系溶剤（Ａ）と、一般式（Ｃ−１）で表される化合物（Ｃ）と、水（Ｗ）とを含有し、前記炭化水素系溶剤（Ａ）と、前記化合物（Ｃ）との沸点の差が３０℃以下である、洗浄剤組成物。式中、Ｒ１及びＲ２は、それぞれ独立に、炭素原子数１又は２のアルキル基又はアルケニル基である。Ｘは、単結合又は炭素原子数１〜４の２価の脂肪族炭化水素基である。但し、Ｒ１、Ｒ２及びＸの炭素原子数の総数は、４以上である。［化１］【選択図】なし
