Why Silver Jewelry Turns Black and How to Clean It

Silver jewelry turns black due to a reaction where silver reacts with sulfur compounds in the air, forming silver sulfide. This process is more common in wetter areas. Below are some professional cleaning methods and simple home remedies to restore its shine.

Professional Methods

Silver Jewelry Cleaner

Follow the directions for use of a commercially available silver cleaner. Generally, you will need to leave the jewelry in the cleaner for some time and wipe it clean with a soft cloth.

Ultrasonic Cleaning

For more expensive and intricate pieces, opt for ultrasonic cleaning at a professional jeweler. Ultrasonic cleaners can reach difficult-to-clean places and break down stubborn dirt.

Electrochemical Reduction

This advanced method is suitable for heavily oxidized jewelry. Electrolysis is used to strip off the layer of silver sulfide from the affected surface. This should be left to professionals.

Home Remedies

Aluminum Foil Method

  1. Boil water in a pot and add a couple of tablespoons of baking soda or salt.
  2. Add aluminum foil to the bottom of the pot and place tarnished silver jewelry on top of it.
  3. The chemical reaction between the silver and aluminum will assist in removing the black silver sulfide.
  4. Wait for about 10 minutes, then take out the jewelry, wash with warm water, and wipe dry with a soft cloth.

Toothpaste Polishing

  1. Apply cheap white toothpaste (non-abrasive).
  2. Use a bit of this on the silver piece, lightly buff with a soft-bristled brush or cotton swab.
  3. Rinse in warm water and pat dry with a soft cloth.

Lemon Juice and Salt

  1. Combine salt and lemon juice to make a thin paste.
  2. Spread the paste over the surface of the silver and leave for a few minutes.
  3. Wash off with warm water and dry with a soft cloth.

Potato Boil Water

  1. Place a few slices of potato in a pot of water to boil.
  2. Once boiling, place the silver ornaments in it and let them soak for about 30 minutes.
  3. Carefully clean the jewelry with a dry and soft cloth to remove the oxidation layer.

Tips

  • Always test any cleaning method on a hidden part of the jewelry before applying it to ensure it does not damage the jewelry.
  • When clean, dry the jewelry well to ensure no moisture is left behind, which could cause further oxidation.
  • Store the jewelry in a bag with minimal exposure to air, which also slows down the oxidation process.
  • Some silver jewelry is intentionally aged to achieve a vintage look, which can be very fashionable. Be sure to distinguish between naturally tarnished pieces and those that have been deliberately treated for a unique style.
