Polishing method: If the surface of the golden ball is scratched by a hard object and some tiny scratches appear, you can wrap the rough silver wiping cloth or polishing wheel with a soft cloth for polishing, and then gently wipe it with a small amount of moisturizing oil or baby oil to remove the scratches on the surface.
