Silver Damaged by Hydrogen Peroxide
Q. I added hydrogen peroxide to Dawn dishwashing soap to soak and clean my Pandora bracelets. Left soaking for a couple of hours. Shocked to find them completely black!
Scrubbed with toothpaste, then baking soda. Worked somewhat, finishes are dull, not shiny. What else can I do!?

A. Line the container with aluminum foil, then fill it with the hot water and baking soda [in bulk on eBay or Amazon [affil links] (you can use vinegar ⇦in bulk on eBay or Amazon [affil links] instead of water too, or even salt/vinegar mix). Soak the silver in the mixture until all tarnish is removed. Then remove the silver, rinse with clean water, and dry with a soft cloth. Polish it with special silver polishing cloth ⇦ this on eBay or Amazon [affil links] (you can use tooth paste or precipitated chalk ⇦ this on eBay or Amazon [affil links] too. There are some You tube videos on that subject .

Q. I had a similar thing happen to my sterling silver ring. I left it in hydrogen peroxide (3%) a bit too long, and it turned the sterling silver black. Is there anything I can do to remove the tarnish & have the sterling silver shining again?

Ed. note: try the washing soda ⇦ this on eBay or Amazon [affil links] and aluminum foil procedure described in thread no. 4785, Bruce.
A. Yes, hydrogen peroxide does react with ANY type of silver.
It will oxidise it very quickly.

A. Use toothpaste and a toothbrush to brush the black off. (Not tooth gel or charcoal. Just good old fashioned tooth paste). Instant effects. This also works if you bleach gold.
