gather all you supplies.
here's the necklace I want to clean. see how dirty the back is? in few minutes it will shine.
cover a bowl with aluminum foil.
put in the bowl 2 teaspoons of baking soda.
put your piece of jewelry into the bowl.
pour boiling water and…
watch the foam.
after 20/30 seconds take out the necklace.
wash it under cold running water, wipe it, and…
