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.
I just tried this on my Tiffany’s heart and ball chain and realized after I started boiling the water I was out of baking soda…put the vigenar and salt in the boiling water anyways and poured into the pan. Wosrt thing that I figured could happen would be it wouldn’t work and I wasted a little vinegar and water..as i pourd the steaming hot liquid into the pan I WATCHED it get cleaned instantly. This works without the baking soda! I wished I had taken a video of it! Coolest thing to see happen! Thank you!
