PURPOSE:To make a dewaxing treatment in a short time by disposing a synthetic resin inside cell contg. a member to be dewaxed and dewaxing liquid into an outside cell contg. constant-temp. water, and displacing the member to be dewaxed while irradiating an ultrasonic wave to said member by an ultrasonic wave oscillator provided in the outside cell. CONSTITUTION:The synthetic resin inside cell 1 made of a PE, etc., is disposed in the outside cell 1 made of a stainless steel. The constant-temp. water B and ultrasonic oscillator 3 are put into the cell 2. The member 5 to be dewaxed and the dewaxing liquid A are put into the cell 1. The ultrasonic oscillation from the oscillator 3 is propagated to the constant-temp. water the inside cell dewaxing liquid member S while the position of the member S to be dewaxed immersed into the liquid A is changed by a member displacing device 4. The member S and the particles of the liquid A repeat the vigorous collision by the powerful accelerating power generated by the ultrasonic resonance of the member S and the cavitation, etc., generated on the member surface, by which the member S is dewaxed in the short period.
