Guide: Cleaning Silver Jewellery

What you need:

A bowl.
500ml hot water (but not hot enough to burn)
1 tablespoon of salt.
Some (preferably recycled) aluminium foil.

Method :

  1. Pour the hot water into the bowl.
  2. Stir in 1 tablespoon of salt.
  3. Tear off some strips of aluminium foil and add it to the bowl.
  4. Submerge the jewellery in the solution and leave for 5 minutes. If the silver is heavily tarnished the process may need to be repeated a few times.

How it works:
Silver tarnishes when the surface of the silver combines with sulphur in the air. The black substance created is called silver sulphide. When placed in a saline solution, in the this case the hot salt water, a chemical reaction occurs between the aluminium and silver sulphide, removing the silver sulphide from the silver surface.[
