All sterling silver will tarnish over time, but it will happen much faster when it comes into contact with agents such as perfume, salty air, sulphur in the air, skin creams, hairspray, chlorine, sea water, perspiration, medication excreted through the skin, and acidic skin ph. Hot and humid conditions also stimulate tarnish. The amount of tarnishing (oxidation) that occurs is dependent on the skin and care habits of the wearer.
To clean tarnish, gently scrub your jewellery with a soft toothbrush in diluted soapy water. Dry thoroughly then gently buff with a jewellery polishing cloth. This helps to remove the dirt and grit that may gather between the links of your necklace causing wear and tear. A twice yearly professional clean will ensure that your jewellery always looks beautiful and wears well. Wear your sterling silver jewellery regularly. Your body oils and the normal buffing of your jewellery against your clothing help to minimise tarnishing.
