|Wire Crochet set (tutorial here)|
I lined a baking dish with aluminum foil, then poured in a few teaspoons of baking soda and salt. Then I filled it with water from my instant-hot tap (you can boil water separately and pour it in), stirred it up, and put my jewelry in. It can take a few minutes, but I could see the change right away. Bright, sparkly silver with no damage to my turquoise or pearls, and no chemicals.
