Another cause is actual corrosion of the non-gold alloys, silver or copper which is mixed into the gold. Perspiration and smog fumes attach these metals and are evident as tarnish that rubs off on the skin. A suggestion is to remove jewelry often and use absorbent powder, free of abrasives on skin that comes in contact with jewelry. You should remove your jewelry before using soaps, cleaning compounds, or detergents, and clean your jewelry often. The word originated with the portable clocks that were carried by the town watchman as he made his rounds.
Gold is both versatile and very easy to keep looking beautiful for years to come.
Its worst enemy, however, is chlorine. Repeated exposure can weaken gold's structure, eventually leading to breakage. Try to keep your gold jewelry away from chlorinated cleaning products, swimming pools and Jacuzzis. To clean, use your jeweler's recommended solution or lukewarm, soapy water. Rinse with clear water, then dry and polish with a soft chamois cloth.
