Normal everyday use and external agents such as air humidity, temperature, pollution levels, contact with cosmetics and skin perspiration can all contribute to reduce the shine of steel, silver and leather surfaces, and change the original appearance of the surface finishes that characterize some models. You can simply preserve the shine of your jewelry using a soft dry cloth or non-abrasive products specially designed and used to clean jewelry. Most of the products on the market for jewelry cleaning can be used without risks as long as they are applied properly, although you should be careful while using products that contain ammonia, alcohol, acids or chemicals that may be too aggressive.
