Should I start another thread on cleaning this? We're not sure where to start.
I'm not sure if this method works with silver plated things, but for .925, .999, or other silver, I would recommend using the method below. I've heard a lot of people talk about how well it works, and the times I've used it, it has worked well for me, too.
Step 1.
Start boiling 2-3 cups water
Step 2.
Line a pan with aluminum foil & add in enough baking soda to cover a small area, about an inch bigger on all sides than what you will be cleaning.
Step 3.
Put your silver into the middle of your baking soda.
Step 4.
Add more baking soda, enough to cover your silver so it can't be seen.
Step 5.
Pour in the water after it comes to a boil. (If the baking soda on top of your silver washes off, you can put some more back on top of it.)
Step 6.
Wait 5 minutes. Then, using latex/rubber gloves, gently scrub the silver with the baking soda for 3-5 minutes. About every minute, dip back into the mixture of boiling water & baking soda to rinse it.
Step 7.
When you are satisfied with how it turned out, take off your gloves and wash silver under cold water for a couple minutes. (Taking gloves off helps to not let more baking soda get on when you wash it. Washing it takes off the baking soda so it doesn't leave a stain, & the cold water cools it off.
Tip: Use tongs to take your silver out of the mixture, as silver quickly gets very hot.
