Wearing silver will keep it looking nice, as once silver is put in a drawer, or in hot pools, it starts to oxidize/tarnish. To remove any tarnish use a silver cloth or silver dip. All your jewellery can also have a good general clean in warm soapy water and scrubbed with a soft tooth brush. You may even want to bring it in to us, or to your local reputable jeweller, for a sonic and buff every now and then to keep it looking really nice.
