Does anyone know what bleach does to silver?
I now know.
It turns it black and greenish colors. I guess it tarnishes it.
When I sort halves I throw them in a plastic bottle with a cleaner degreaser stuff called mean green. I leave them soak in that stuff for a couple days and it gets all the grease and grime off the coins and makes them a little shinier.
Well I ran out of mean green and thought bleach might clean them and I was very wrong.
So I guess my question is can thse be cleaned? My friend said silver cleaner will work and that all you have to do is dip them in the cleaner but these coins look pretty black and tarnished.
Does anyone know if the silver cleaner would work or what would be the best kind to get.
Thanks

Bleach is acidic. It will cause the silver to tarnish quickly. You need a chemical solution to solve your problem:
Use Aluminum foil, 1/2 cup baking soda, 4Tbsp salt, and 6 cups of warm to hot water... mix everything except the AL foil together well and then put in the silver. Stir and rub a bit with your fingers. After throughly mixed for a few minutes, add the aluminum foil. Make sure that all coins are touching the foil inside the solution. (you may have to remove the coins, put in the foil, then lay the coins on top of the submerged foil)
Remove coins after 1 or 2 minutes. |

Nice!
If I may nitpick momentarily... Bleach is a base not an acid, and it is a wonderful oxidizer, which caused the tarnish on the coins.
May I ask as to why you clean a silver coin at all?
EDIT: I had to check myself and now I would like to correct myself. I have now learned:
So, yes, Hypochlorous acid is an acid albeit a pretty weak one. However, ClOH is too unstable to simply buy and store. If you wanted to treat your pool or make your own bleach, you would actually purchase sodium hypochlorite, which is the same molecule except with the hydrogen atom replaced with a sodium atom. This "salt" is stable. However, let's think about what happens when it is added to water. The salt dissociates into Na+ and OCl-. OCl- is the conjugate base of hypochlorous acid. OCl- reacts with the H3O+ that is naturally present in water, meaning some of the OCl- remains as the dissociated salt (Na+ + OCl-), while the rest reacts to form hypochlorous acid (ClOH). The proportions would be the same as above, meaning only 0.017% of the OCl- would remain in this form – the other 99.983% would react with H3O+ to make ClOH and water. So, what you normally would buy to make bleach is actually a base, though once in water, you have both the acid and base present. While it seems strange at first to think of an acid and a base coexisting, this is actually pretty common in nature (in fact, a similar reaction occurring in your blood is critical in keeping your body's internal pH just right!)

Long story made short:
Don't put Ag in Bleach, that makes Ag black!!!!!!!!!!!!
Soak Ag coins in mineral oil or mayonnaise overnight (or for a month to clean the gunk) off them.
(Ketchup or Catchup will work, too, if you only give them a 30 min., or less, soak.
It's a rather strong acid and will remove Ag if left in long enough.) |
There's profit if you melt things!!
