西山 5 Anyone who has worked at with jewelry knows you can not remove deeper scratches with a weak abrasive (polishing cloth) it takes steps of polishing for that type of thing. These are great for the final steps of polishing after getting out all the scratches or if something has tarnished a bit to shine it back up. Which is exactly what a it is suppose to do. I work a lot with jewelry so I’ve purchased them 4 times as it’s a very handy item to have.
