Sterling Silver is defined as 92.5 percent pure silver, making it more valuable and precious than simple silver-plated jewelry pieces. Like all metals, sterling silver is prone to tarnish and it scratches with heavy use. Sterling must be polished and buffed to be restored to its original luster. Removing scratches from sterling silver can be done from home, but deeper scratches and gouges should be sent to a professional to be vigorously polished and buffed to restore the original shine.
Mix a tablespoon or so with a few drops of water until a thick, goopy paste is formed. Make sure all water is appropriated into the baking soda so it's no longer grainy prior to using.
Use a polishing cloth or pure cotton rag to apply the baking soda paste to the sterling silver bracelet. Rub the paste into the bracelet with vigor until the silver begins to shine. Check the silver after several rubs to see if the scratches have faded.
Wipe the polished bracelet dry with a clean, dry polishing rag or pure cotton cloth. If scratches remain, repeat Step 2 and buff dry again until the scratches are gone.
Take a bracelet with deep scratches that do not respond to home polishing to a jeweler or jewelry repair specialist. The jeweler will use a special polishing machine to remove some metal from the bracelet to disguise the scratches.
