Home made jewelry cleaner...I tried it & worked quite nice on my bridal ring set! Items you need: Piece of aluminum foil, boiling water, baking soda, salt, heat safe bowl.-Fold up a piece of aluminum foil & put in bottom of heat-proof bowl. Sprinkle some salt & baking soda at bottom then place jewelry in bowl. Sprinkle more baking soda & salt. Pour boiling water over the top until it covers jewelry. Jiggle jewelry to loosen dirt. Let sit for a while. Remove & rinse jewelry in cold water.
