1. Reasons for silver jewelry turning black It is normal for silver jewelry to tarnish due to natural phenomena. This occurs because sulfur and oxides in air and other natural media can corrode silver to some extent.When silver jewelry is worn for a long time, sulfur combined with silver forms a black silver sulfide film on the surface. It initially appears as small spots, which gradually spread into patches as the sulfidation phenomenon intensifies. This is commonly referred to as silver tarnish, turning black and affecting the surface luster of the silver jewelry. People often mistakenly think it's discoloration. The chemical reaction equation is: 4Ag+H2S+O2=2Ag2S+2H2O 2. How to clean silver jewelry after sulfidation? Squeeze a little toothpaste, add some water to create rich foam, wipe with a soft cloth until shiny. Use a soft bristle toothbrush to clean gaps, then rinse with water.For complex components and chains, you can soak them in toothpaste water with foam and gently rub repeatedly before rinsing with clean water.When sulfurization is severe, you can use professional silver cleaning solution for cleaning.Although silver cleaning solution is claimed to "not damage silver," it is still a chemical preparation. It's recommended not to use it unless absolutely necessary. 3.How to maintain silver jewelry daily? The best way to maintain silver jewelry is to wear it daily, as human body oils can give silver a warm and natural shine (of course, there are exceptions where someone's sweat contains substances that turn silver black).When wearing, wipe the surface of the silver jewelry with a soft cloth or silver polishing cloth every day to maintain its luster and dryness.When not wearing, gently wipe the surface with a soft cloth to remove moisture and dirt, then store in an airtight bag to prevent oxidation and tarnishing due to air exposure.
