So the question is; how can we slow this down? - Contact with water: Not a good idea. But it is unlikely to cause permanent damage. Just make sure to dry it afterwards. - Swimming pool: Chlorine is a harsh chemical, so if you accidentally forget to remove your jewelry before taking a dip, make sure you rinse and clean it thoroughly afterwards. - Contact with sweat: The chemicals in our bodily fluids accelerate the tarnishing process of silver and can leave colored marks on the skin. The best thing to do is to rinse and dry your jewelry. - Chemicals in lotions and perfumes can also cause silver jewelry to tarnish.
