All sterling silver will tarnish naturally over time, just like every other piece of silver jewellery you own. But when it comes into contact with substances like perfume, salty air, sulphur, skin creams, hairspray, chlorine, and an acidic sweat pH, it will happen much more quickly. The wearer’s sweat and maintenance practices have an impact on how much tarnishing (oxidisation) takes place. Therefore, Tarnishing is not a manufacturing flaw.
But even if your sterling silver has tarnished over time, you can easily restore and refresh it at home with products like baking soda in warm water, non-gel toothpaste and gentle toothbrush or silver washing liquid. To refurbish your silver at home, there are numerous DIY options. This is the appeal of precious metals as well as their capacity for sustainability.
During usage, it is possible that your silver will accidentally react in ways you can’t fix on your own. In scenario where the DYI methods recommended above may not work, which is very uncommon; OR you just want to renew jewellery after long term use for freshness and are not into DIY, please visit a local silversmith to have your silver refinished & renewed. It is a common routine silver owners do to have their old silver professionally refinished and plated.
