I love projects where you have an immediate improvement (painting, cleaning, etc.) I have several plain silver chains that are severely tarnished & I did not feel like using my stinky jar of silver cleaner. It only takes a quick dip in the liquid & they look like new but the fumes coming off of that stuff are vile (maybe that is from the sulfuric acid?) I also had a large silver spoon that desperately needed help, so I looked online & picked out the easiest method with the least ingredients I could–and it worked!
I lined a 9 x 13 glass baking dish with aluminum foil. Then I set one silver chain and the silver spoon on top of the foil. I boiled 8 cups of water & added it to the dish. Next I sprinkled 1/2 cup of baking soda on top of the water (the water will bubble a little.) I let it sit for 5 minutes, then I removed the silver pieces, rinsed them with cold water, and polished them with a soft cloth (an old t-shirt.) I poured the baking soda water down the drain & threw out the aluminum foil. The necklace only required one treatment, but the spoon was more tarnished and required three treatments.
This is natural, easy way to tackle your tarnished silver–just be sure that the silver pieces are not overlapping each other & only treat jewelry without any stones. There was a bit of a metallic odor that faded quickly but nothing like the chemical jewelry cleaner I have used in the past!
