2. Avoid direct contact between platinum jewelry and highly volatile substances such as perfume and hair gel.
3. If the platinum loses its luster due to stains and dust after wearing for a period of time, just soak the platinum in a neutral detergent diluted with warm water and clean it, then take out the flannel and dry it.
4. Avoid putting platinum jewelry together with other jewelry, especially diamonds, because their hardness will lead to mutual friction and scratches, so they should be stored separately in cloth boxes.
Bian Xiao suggested that platinum jewelry should be sent to a professional jewelry store for cleaning once every six months. In addition to cleaning, the platinum surface will be covered with tiny wear marks due to long-term friction, which will also reduce the brightness. Polishing the platinum surface with platinum cloth on weekdays can have a polishing effect and restore the original beautiful and bright light of jewelry.
The reason why gold turns black
1. After a long time, gold jewelry loses its luster. Daily wear or environmental factors may make gold jewelry lose its bright color. For example, in dry areas, the air contains a lot of fine dust, which will form a kind of "body sandpaper" after being polluted by human body, which can grind gold jewelry into extremely fine debris and appear local black stains. It is worth mentioning that talcum powder or moisturizer also contains similar particles, which will also overshadow the above-mentioned gold jewelry.
Countermeasure: It is safe to clean gold wares with ultrasonic wave. Don't wear gold ornaments to swim in the swimming pool. It is too hot to store gold ornaments. When cooking, be careful not to damage your gold ornaments with hot smoke.
2. Reasons for the blackening of gold ornaments: harmful substances such as chlorinated substances, lactic acid and urea ammonia discharged by human body will contact with silver and copper in gold ornaments to produce chemical reactions, resulting in dark black silver chloride and copper sulfide. This chemical salt sometimes falls from gold jewelry, and also pollutes the wearer's skin, leaving a very obvious black stain.
Countermeasure: Cleaning with mild soap and soft brush (baby toothbrush can also be used) is the easiest way. Do not use toothpaste containing abrasives. Water column can also replace soft brush. After cleaning, the gold ornaments can be dried with an old towel made of cotton thread or put on a towel to dry naturally.
3. The gold in gold jewelry will be worn less and less, but the consumption of this quality is invisible to the naked eye. At present, cosmetics have become one of the indispensable "roles" in people's lives. If it is applied to the skin wearing gold jewelry, it will undoubtedly provide an opportunity for cosmetics containing chemical substances and gold jewelry that is most afraid of chemical erosion, and the result can be imagined. Some cosmetics also contain some fine hard particles, which can constitute another kind of dirt, thus wearing away gold jewelry.
Countermeasures: Avoid contact between gold ornaments and cosmetics and skin care products. You'd better get rid of your gold ornaments before you go to the barber shop. Shampoo may also consume your gold.
