。(Effects) The present invention includes an immersion cleaning device containing a strong alkaline cleaning solution, a liquid draining device that injects an air jet stream toward the mold to be treated, and a neutral cleaning fluid directed toward the mold to be treated. A liquid injection type cleaning device that sprays high-pressure water is arranged in order, and each device is connected by a conveyance device. After the mold to be treated is immersed in a strong alkaline cleaning solution, the alkaline cleaning solution adhering to the mold is removed by an air jet. The mold release agent stuck to the mold surface is removed by spraying a neutral cleaning solution at high pressure towards the mold to be treated, so the mold to be treated is immersed in a strong alkaline cleaning solution. By doing this, the stuck mold release agent is swollen, and then the swollen mold release agent is peeled off from the mold surface by high-pressure jetting of a neutral detergent solution, so that the specified product precision can be achieved without scraping the mold surface.
