It tends to tarnished over time, so it requires cleaning every now and than. You may use a polishing cloth or baking soda with foil: Put the silver jewellery on top of the foil and pour moderately hot water over it. Add a couple of tablespoons of baking soda to the water and swish it around to dissolve it. Let the silver jewellery soak for about 20 to 30 minutes. Rinse it well and dry it with a soft towel. You may keep your silver jewellery in a sealed plastic bag to slow down the process of tarnishing. Each item is gift box wrapped inside of a bubble envelope.
