Don't try cleaning silver by soaking in household bleach

[DrDime]

Accidentally posted the result in the bitcoin thread :-/

[Kman]

Doesn't look the best lol

 

What made you bleach it? 

[DrDime]

Well, I initially soaked it in ammonia to see what happened. It did seem to help with general gunk so I thought I'd try bleach. Works a treat on the sink...

How to turn a beautiful silver coin into an oreo, so now we know

and for the next trick... cleaning it all off with a brillo pad

[Cornishfarmer]

Does it still look that dark grey, think it looks good

[FTYBR]

Any chance electrolysis will clean that up?

I'm sure a few of you have tried before but basic instruction/videos quite widely available. Here's one anyway...

My new pride and joy:

[DrDime]

Spot the difference....

[Cornishfarmer]

Try bit of sandpaper on the eagle, that shiney will be a great contrast

[Kman]

Spot the difference....

 

I like that you have put it back in the capsule to avoid damage 

[DrDime]

@fylbr. Yes I'm sure I could clean it up with the aluminium and bicarbonate method

[Danny-boy]

Well I reckon it is cool as hell.

Tempted!!!!

[SilverPirate]

Why not keep the tarnished one in your pocket as a keep sake and it will rub here and there and look nice.

[Ares]

That actually looks pretty cool, like an SR-71.

[Keithoil]

Maybe you should patent it and then sell it to the Mints.

 

At least that way we would not have to worry about toning anymore.

 

The only thing is there would be more sets to co^**ct. I cannot say the word it is like a very bad swear word

 

As there would be a black version of every coin.

[HighlandTiger]

Try silver polish....

[DrDime]

So I tried the aluminium foil and bicarbonate / salt method on this coin. It's gone from a dark grey to a lighter grey but it still does not look even like a piece of metal. Any ideas fluttershy?

[Fluttershy]

I can`t think of anything that would take it back to it`s original condition to be honest, the chlorine has dislocated the silver structure making the surface porous/spongey, and as you say very non metalic looking.

other than flashing the metal at high temp very quickly to surface melt the coin a little (very tricky!) you`ll just have to polish it back down to the metal again and hope the damage didn`t go too deep.

some Silvo and a plastc scour pad would do the job, but you`ll never get it back to original condition again, sorry

[DrDime]

Ok no worries. I'll try putting it on the George Forman for 10 secs
