Abstract: A cleaning device is configured to include a first cleaning tank that holds water to which a small amount of an additive is added as a first cleaning fluid, a second cleaning tank that holds water, a water-based cleaning agent, an alkaline cleaning fluid, or a hydrophilic organic solvent as a second cleaning fluid, a first microscopic air bubble generation device, a first circulating pump, an ultrasonic wave emitting device, and a carrier device. Hydrophobic oil is removed by a cleaning target being exposed to the first cleaning fluid including microscopic air bubbles sprayed from a nozzle in an interior of the first cleaning tank, after which hydrophilic oil is removed by ultrasonic cleaning in the second cleaning tank.
