Abstract: Nowadays, common ornaments include gold, silver, platinum, jade, diamond, pearl, etc. Do you know how to clean these kinds of jewelry? If you are not clear, let's take a look at the following methods. The following describes in detail the maintenance methods of gold, sterling silver, platinum, pearl and diamond jewelry, as well as the maintenance details.
1. How to Clean Gold Jewelry?
The discoloration or fading of gold jewelry is closely related to human sweat. 99% of human sweat is water, and the other 1% is waste and harmful substances in the human body, such as chlorine, lactic acid, urea ammonia, etc. After contacting with silver and copper in gold jewelry, these substances will produce chemical reactions, producing silver chloride and copper sulfide, and showing dark chemical salts. This chemical salt often falls from gold jewelry, polluting the wearer's skin and leaving a very obvious black stain on the skin. At present, cosmetics have also become one of the indispensable "roles" in people's life. If it is smeared on the skin where gold jewelry is worn, it will undoubtedly provide an opportunity for cosmetics with chemical substances and gold jewelry that are most afraid of chemical corrosion to "get together without family". The results can be imagined. Some cosmetics also contain some fine hard particles, which can form another type of dirt, thus wearing gold jewelry. Regional environmental factors may also make gold jewelry lose its bright color. For example, in relatively dry areas, there is more original fine dust in the air, which will form a "human body sandpaper" after infecting the human body. It can abrade gold jewelry into extremely fine debris and produce local black stains. It is worth mentioning that talcum powder or skin cream also contains similar particles, which will also make gold jewelry pale as above.
Treatment: Brush with soapy water mixed with a little alcohol, rinse and dry.
2. How to Clean Sterling Silver Jewelry?
Generally, the sterling silver ornaments sold on the market are 925 silver, not 999 silver. Because 925 silver is alloy silver made by adding other metals, 925 silver is also recognized as sterling silver internationally, with a proportion of 7.5% alloy and 92.5% silver. The ornaments forged from such sterling silver are stronger and less easy to wear and deform. The real 999 silver is as soft as pure gold. Only the ornaments made from alloy sterling silver can be durable, It will not deform after wearing it for a few days, and the surface is worn too much and needs continuous polishing.
How to Maintain Sterling Silver Jewelry?
The biggest cause of silver oxidation is oxygen in the air, so blocking the air is the best way to maintain it. For example, put silver jewelry in a sealed plastic bag and then put it in a jewelry box to block the contact between the air and silver. When silver oxidizes, you can use silver washing water or silver wiping cloth to polish the silver jewelry, but the silver washing water is more lethal, so you can use silver wiping cloth to wipe as much as possible when you have to, If you use silver washing water to wash the silver, you should immediately pick up the water and rub it gently, clean the chemical substances on the surface, and dry them with a hair dryer, otherwise, the oxygen in the water will accelerate the oxidation of the silver! In addition, soak it in 90-degree alcohol for 12 hours, dry it after wiping, or squeeze the toothpaste on a dry cloth to directly wipe it.
3. How to Clean Platinum Jewelry?
When you do housework, do not let the platinum jewelry you wear get stained with oil or bleach. The oil will affect the luster of the jewelry, and bleach may cause spots on the jewelry. Although young people want to be conspicuous, they must not wear platinum jewelry and gold jewelry at the same time, because gold is soft. If it rubs against each other, gold powder will adsorb on platinum, making platinum yellow and affecting its unique pure luster. If frequently worn, platinum jewelry should be cleaned once a month as far as possible to maintain its shiny luster. It can be cleaned with a special jewelry cleaner or cleaned by yourself. The correct method is: Rub the toothpaste on the towel, rub the platinum jewelry back and forth with your hand to remove the fine lines and dirt on the surface, then clean it with diluted household detergent, and then rinse it with clean water, and the luster can be restored as new. If your platinum jewelry is inlaid with diamonds, it is recommended that you send the platinum jewelry to the jewelry store every year for inspection, timely professional cleaning, and repair, so that the platinum diamond jewelry can always be worn. Just like beautiful flowers and plants need careful care, your platinum jewelry needs your careful care to spend a good time with you.
4. How to Clean Pearl Jewelry?
Although the color of the pearl is beautiful, it can not stand the test of a long time. Generally, after several decades, pearls will become ordinary yellow and lose their beautiful luster. This is what the saying goes: "Old pearls are yellow.". Why do pearl ornaments turn yellow after being used for a long time? This is mainly because the physical properties of aragonite minerals that make up pearls are unstable, and they will become ordinary calcite over a long period of time. Aragonite and calcite have the same chemical composition, but their crystalline morphology and luster are different. This is the reason why pearls change color. After the pearl turns yellow, there are some remedies, namely, soaking it in dilute hydrochloric acid, which can dissolve the yellowing shell, so that the pearl can regain its brilliant and charming color. However, if the color becomes very strong, it will be difficult to reverse. You should wear pearl jewelry after makeup, because any beauty products (powder, foundation cream, etc.) will damage the pearl, including perfume and hair gel. After wearing, the pearls should be soaked in clean water, washed, dried, and then stored, otherwise the pearls will turn yellow easily.
5. How to Clean Diamond Jewelry?
Add water and washing powder to the container, put your diamond ring in water for 10 minutes to soften the dirt on it, then brush it with a toothbrush, rinse it with water and then rinse it with 90 ° alcohol, and finally take it out to air. Turquoise jewelry: Be careful when wearing turquoise jewelry. It can absorb grease. Do not wear turquoise jewelry when you wear sunscreen or cream. Because once turquoise is dirty, it is difficult to restore it to its original state.
