につながるという問題が生じる。In the above-described cleaning apparatus, a batch process is performed in which an amount of members to be cleaned that can be stored in a barrel is put into a cleaning tank at a time, and after the cleaning is completed, the members to be cleaned are removed. Therefore, a barrel and a device for taking the barrel in and out of the cleaning tank are required, which causes a problem that the equipment becomes large and the cost increases. Further, if a cleaning liquid that separates and floats a substance to be cleaned (for example, oil) from the member to be cleaned is used, when the barrel is taken out of the cleaning tank, the substance floating near the upper surface of the cleaning liquid reappears on the member to be cleaned. This causes a problem that the member to be cleaned cannot be efficiently cleaned. In order to solve this problem, it is conceivable to use, as a cleaning liquid, a solvent that dissolves a substance to be cleaned or a surfactant mainly intended to form an emulsion by colloidalizing the substance to be cleaned. However, this type of cleaning liquid has a problem that when cleaning the member to be cleaned, the cleaning performance is immediately reduced, so that a large amount of cleaning liquid is consumed and a large amount of waste liquid after use is treated, leading to an increase in cost. Occurs.
