This method works great on sterling, silver, gold, costume jewelry metals.. But do be careful if you’re got a lot crystals glued into a setting and limit soaking to no more than 90 seconds – or you might melt the glue. Also, don’t immerse natural pearls in this solution – it’s too caustic. It is however, fine for most gemstones and this homemade jewelry cleaner works wonders on cubic zirconia (CZ stones)! And in case you’re wondering ….it also works fab for cleaning silverware, silver frames or any silver home decor!
If the jewelry is very dirty or very tarnished – like silver or gold – then you may need to repeat the process so just add a little more baking soda and more boiling water – but make sure it’s boiling, that’s key! You can also use a toothbrush to get in all the nooks and crannies of detailed jewelry. Be careful with precious gems, stones and metals.
