However, it won't make "silk purse out of a sows ear"!
Any excessively tarnished/blued or particularly dirty areas will benefit from a polishing and produce a pleasing shine, but the cloth won't entirely remove these imperfections/patina. It's better to keep on top of things and adopt a regular maintenance/polishing schedule, all things with benefit, but some items will benefit more than others. Recommend item!👍
