You may be concerned about tarnishing your plated jewellery further by cleaning it. Even so, you should be cleaning your jewellery from time-to-time to keep it looking its best. Avoid rubbing the jewellery and simply clean it in warm soapy water.
- Remove all plated jewellery when doing pretty much anything that involves heat or moisture...so...bathing, swimming, exercise....and anything else you can think of where the jewellery may get wet.
- After bathing/showering, wait until you're dry before putting on your plated jewels and apply all lotions and perfumes on before putting the jewellery on. Different chemicals in lotions and perfumes can seriously tarnish jewellery. It's best to avoid any tarnish with plated items as they aren't as easy to clean as silver and gold pieces.
- Store gold plated jewellery in the box it came in. Don't throw it in your jewellery box with everything else as the friction of rubbing up against other metals can wear away at the layer of gold. And leaving it lying around increases the risk of tarnishing.
- Don't sleep in your plated jewellery for the same friction-y reasons!
- DON'T use any abrasives to clean your plated jewellery! So, ignore all the advice online to use baking soda or a toothbrush to clean your plated items! Anything abrasive will remove the layer of gold or rhodium.
