The most simple and basic way to maintain your jewellery and keep it ready to wear is to gently wipe off excess make up and skin oils after each wearing. Use a nub free, 100% cotton cloth and gently wipe the piece clean using only the soft pads of your fingers. Store in jewellery’s tissue or a soft bag before putting in jewelry box.
To help retard tarnish on sterling silver, wrap the piece in those jewellery's tissue paper and place it inside a plastic zip lock bag and seal.
Never use anything but 100% cotton as a polishing cloth since paper, polyester, and coarse fabrics often contain wood fibers or synthetics. These materials may impart fine scratches in the metal, especially on sterling silver.
Don’t forget to take off your fashion jewellery before bathing and sleeping. Swimming especially in salt water with costume jewellery is not recommended too.
