1. Dust removal to clean the dust and scale of gold jewelry, the simplest way is to use a soft brush dipped in hot water, and it is best to use a degreasing cotton ball dipped in soapy water and anhydrous alcohol for scrubbing. However, it is not allowed to use abrasive particles (such as toothpaste, polishing paste, fine sandpaper or fine abrasive cloth) for scrubbing to avoid reducing the weight of gold and causing losses 2. Washing of gold jewelry when washing gold jewelry, first put the gold jewelry into the container, then add water to the container, then add a small amount of ammonia, then close the mouth, shake it vigorously back and forth, and then take it out to dry. When wearing gold jewelry, the buckle switch should also be maintained, and a little sewing oil should be dripped to the switch regularly to prevent the micro spring in the switch from rusting 3. Removal of white spots on gold jewelry since some of the cosmetics on the market contain trace mercury (mercury), such as phenyl hydroxy mercury and mercury dichloride, etc., the gold jewelry will appear white spots or turn white after contact. At this time, do not use a knife or sandpaper to polish. As long as the jewelry with white spots or whitening is baked in the fire, and then wiped with a soft cloth, the gold jewelry will restore its original luster.
After wearing gold jewelry for a period of time, some friends think that the gold content is insufficient. In fact, if you don't pay attention to wearing gold jewelry in daily life, it will inevitably make the gold jewelry change color,. Gold, soft in nature, strong in ductility and not easy to be corroded. As gold is a precious metal, generally gold products are often mixed with silver, copper or iron, which can make gold hard, change the color of gold or reduce its high price. Products such as gold sheet, gold foil and pojin are commonly made of alloy materials or only partially made of gold. Gold and copper are mixed, usually mixed with some silver. The cast copper ware is pale yellow, even green. However, after years of burial in the soil, the salt in the soil removes the lighter metal on the alloy surface, leaving a layer of pure gold flakes. The pale yellow will change to a dark yellow, and this gorgeous color should be retained. Pure gold products generally do not have much change, but for alloy utensils, because small voids can be formed during processing, when water enters people, corrosion will occur. For the same reason, it is inevitable that there will be cracks, voids and tiny holes in the gold objects that cannot be seen by the naked eye. Water or water vapor can drill in, causing electrolytic corrosion and constantly destroying other metals except gold. Most of the common corrosion phenomena of gold ware are the result of oxidation of the attached parts (such as copper or silver). The copper oxidizes to form a green film, which can be removed by acids or ammonia. The red film on the surface can be removed with a little hydrochloric acid; If it is a thin gold leaf ornament, it can be flattened by pressing. If it is relatively large and easy to break, it needs to be properly heated and tempered to soften and flatten. Gold jewelry is rarely infringed by external factors. However, all mechanical damage is very dangerous, and the lightest impact can cause distortion, crumple, scratch and damage the gloss of the surface if it is lightly brushed with a rough cloth. The house where gold jewelry is kept must be kept dry and free of dust and air pollutants. The temperature is 18-240c and the relative humidity is 40% - 50%. If conditions permit, the gold jewelry shall be packed in the brocade cover and cotton padded box, and the pieces shall not collide with each other. Do not keep gold jewelry with other metal products. To remove the dust with a soft brush, wipe it with a soft antelope skin. If cleaning is necessary, it can be carried out with ether, gasoline (benzene), neutral soap foam or ammonia (10% concentration), and then washed and dried with distilled water. It is not allowed to wipe with any coating or soft antelope skin.
1. To protect the luster of gold jewelry, you can apply a thin layer of nail polish on it 2. If there is a black film on the surface, use 2G of salt, 7g of baking soda, 8g of bleaching powder and 60ml of water to prepare a "gold ware cleaner". Put the gold jewelry in a bowl and pour the cleaner. After 2 hours, take out the gold jewelry, rinse it with water (preferably not hard water), bury it in wood chips and dry it, and then wipe it with a soft cloth 3. For the ring set with gems, roll a piece of cotton with a popsicle or matchstick. After wetting it in the mixture of toilet water and glycerin, scrub the frame of the gems, and then polish the ring with a flannel cloth. Never scrape with sharp objects such as blades 4. Salt and vinegar are mixed into a cleaning agent, which can be used to wipe pure gold jewelry and keep it fresh for a long time 5. The luster can also be restored by wiping with toothpaste or scrubbing with hot concentrated rice soup
in addition, if the smooth surface of the full gold jewelry is worn, it can be scraped with a polishing pen and an agate knife to flatten the scratches and restore the brightness of the gold. At home, the smooth side edges of agate products can be used instead, which is equally effective. The specific method is to scrape with water or water with household detergent. However, this method can only be used in smooth places. It cannot be used in places with surface treatment such as embossing, sandblasting or sanding. This method is used for the smooth surface of pure silver (925 is not pure silver, at least 99.6% is pure silver)
I hope your gold is as bright as new. Thank you
