PROBLEM TO BE SOLVED: To provide a cleaning method which can clean a wide range of dirt from organic to inorganic one, can suppress occurrence of water stain after cleaning, and enables repeated use of a cleaning agent composition.SOLUTION: There is provided a cleaning method which includes: a cleaning step of applying a physical force to a cleaning agent composition made from two phases of an organic solvent (A) phase and a water (B) phase to form W/O macro emulsion, immersing a substance to be cleaned into the formed W/O emulsion, and cleaning the substance to be cleaned; a draining step of immersing the substance to be cleaned into a draining tank made from the organic solvent (A) phase, and draining the substance to be cleaned, after the cleaning step; and a rinsing step of immersing the substance to be cleaned into a rinsing tank made from the organic solvent (A), and rinsing the substance to be cleaned, after the draining step, where the organic solvent (A) phase is excellent in draining property.SELECTED DRAWING: None 【課題】有機から無機までの幅広い汚れが洗浄可能であるとともに、洗浄後に水シミの発生を抑制することができ、かつ、洗浄剤組成物の繰り返し使用が可能な洗浄方法を提供する。【解決手段】本発明の洗浄方法は、有機溶剤（Ａ）相と、水（Ｂ）相の２相からなる洗浄剤組成物に、物理力を付加してＷ／Ｏマクロエマルションを形成し、形成したＷ／Ｏマクロエマルションに被洗浄物を浸漬して洗浄する洗浄工程と、前記洗浄工程後、前記有機溶剤（Ａ）相からなる水切り槽に前記被洗浄物を浸漬して水切りする水切り工程と、前記水切り工程後、前記有機溶剤（Ａ）相からなる濯ぎ槽に前記被洗浄物を浸漬して濯ぐ濯ぎ工程と、を含み、前記有機溶剤（Ａ）相は、水切り性に優れることを特徴とする。【選択図】なし
