1. Prepare the electrode polishing box, remove the backing adhesive of the polishing cloth, stick it inside the electrode polishing box, pour the polishing powder (0.05um) onto the polishing cloth, wet the polishing powder with distilled water, and mix it into a paste. 2. Place the electrode vertically on the polishing pad, draw an "8" shape or a circle clockwise or counterclockwise, or a straight line left or right, and polish it. At this point, it must be noted that the electrode must be perpendicular to the polishing cloth. After polishing, rinse the electrode surface clean with distilled water
