This cleaning solution is to de-tarnish silver: line your sink with aluminum foil, add 1/2 c table salt, 1/2 c. baking soda, fill with hot water, then dump in all the silver. Let sit for about 30 min.
I put in some silverware that I found at a junk/antique and it did a nice job of removing a good layer of the tarnish. For a truly nice shine, I did need to finish off with some silver polish. Overall, though I was pretty impressed by how much tarnish it really took off. The biggest tip is to be sure to let it soak for at least 30 minutes.
