Please clean your brass, copper and silver jewellery with a soft rag (old cotton T shirt is excellent). You can use a silver cloth, but do not rub too hard to avoid removing patina.

Silver jewellery: for the high-polished work use a silver cloth with some elbow grease. Alternatively, purchase a product called Solvo, made by Autosol, from Halfords (excellent for restoring high finish).
