Jewelry care
Silver
Silver should be kept absolutely dry.
The safest and most effective way to polish sterling silver is to wipe it gently with a soft cloth.
You can clean your silver jewellery with soap and water or with baking soda and water. You can make a paste from baking soda and water, apply a small amount onto a cloth or tooth brush and scrub gently. After you’ve given your jewelry a good cleaning, you can finish the process by using a polishing cloth that’s specifically for sterling silver.
Gold
To keep its shine, you should clean your jewelry regularly with a solution of 10-parts warm water and 2-parts dish soap. A few extra tips: Soaking is the key: per Real Simple, you should soak your gold jewelry pieces for 3 hours and then scrub them gently with a very soft brush.
