The invention belongs to the technical field of metallic copper surface clearing processes and particularly provides a metallic copper surface scale treatment process. The metallic copper surface scale treatment process comprises the following steps of: preparation work, chemical polishing, water washing, laying, drying and washing liquid maintenance; a removing device adopted by the process comprises a polishing module, a material frame, a laying module and a drying module; the polishing module comprises a box body, an ultrasonic wave generator, a heating tube, a water tank and a closing plate component; the two sides of the box body are each provided with a sliding chute which is matched the closing plate component in a sliding manner; a permanent magnet is fixedly installed at one end of the closing plate component; a position, corresponding to the sliding chutes, of the outer side of the box body is provided with a guide rail; the guide rail is slidably connected with a pulling magnet; and the pulling magnet slides in order to open or close the bottom of the box body. According to the metallic copper surface scale treatment process provided by the invention, air flow is fed viathe material frame so that a part is rolled over in the washing liquid, and thus the shortcomings of manual rollover are overcome; and the utilization rate of the washing liquid is increased by adopting a process that the washing liquid is isolated in a layered manner and the washing liquid containing precipitate dirt is independently removed.
