A method for treating a surface of a metallic part in particular of a turbomachine includes a step of shot-peening a surface of the metallic part using metallic beads and a step of cleaning the surface of the metallic part after the shot peening. The cleaning comprises step includes applying a magnetic cleaning paste to the surface of the metallic part in such a way as to remove any residues of metallic beads.

Smoothness of glass is improved. A polishing slurry (A) contains amorphous carbon and water, and a total amount of the amorphous carbon and the water is equal to or more than 90% of the whole polishing slurry in terms of mass ratio.
