Buff a pea-sized amount of a finer-grit diamond paste on the surface.
Try to spread the paste around the center of your project, then rub it in with a cloth. Continue buffing the surface until you’ve polished and rubbed the entire surface. By the time you finish, there shouldn’t be much visible paste on your project.
Clean off any excess with a baby wipe.
Take another baby wipe and clear away any leftover residue from the diamond paste. Keep wiping until the surface looks and feels smooth.
