Silver ornaments are easy to oxidize in the air to produce black substances, which affect the appearance. Salt water contains chloride ions. After soaking in salt water for a period of time, the surface of silver is reduced to silver ions and then becomes metallic silver. The surface can achieve high reflectivity, so most people use salt water to clean silver ornaments. In the specific operation, you need to prepare a glass, pour boiling water into the glass, and add a proper amount of salt until the salt melts.
When the salt water is cooled to a suitable temperature, it usually takes about 20 minutes to 30 minutes to soak the silver jewelry in the salt water. Remove the silver jewelry from the salt water, rinse it with clear water, and then wipe it with a dry towel or toilet paper. Note that this method is suitable for ordinary silver jewelry, precious silver jewelry or jewelry inlaid with silver gems, and it is forbidden to clean it in this way.
Recommended cleaning methods for blackening silver ornaments;
1, wipe the silver cloth
When the silverware turns black, it can be cleaned with a silver wiping cloth, which is a special tool for cleaning silverware. Wrapping silverware with wiping cloth and repeatedly wiping it for a moment can quickly remove the black dirt on the surface of silverware and restore its original color.
2. Toothpaste
When silver turns black, it can also be cleaned with toothpaste. After applying a small amount of toothpaste to the surface of silverware, dip a toothbrush in water and brush the surface of silverware repeatedly. After the black dirt on the surface is brushed clean, rinse it with clear water and dry the water.
3. Coke
Blackened silverware can also be cleaned with coke. After the silverware is directly soaked in cola for a period of time, the dirt on the silverware surface will gradually fall off. At this time, the silverware can be taken out and washed with clean water.
