Need help cleaning copper

marmac

I need help here. I have a 1832 half cent vf-ish. I talked to a well respected copper specialist recently and he advised me to soak in olive oil. I did and the coin is a 100% better looking, it removed much of the gunk and grime that was on the surfaces. Where I stand now is that the feilds are free of the gunk but there is still a lot of it tucked in the date,stars, and all the nooks and crannys of the devices. This coin's sentimental value far outweighs its monetary value to me.

How can I go about removing this grime without damaging the coin? I have thought about it for a few days now and silly as it may sound I thought if I could put a little bit of "pressure" behind the olive oil I could get it off. A water pistol filled with oilive oil came to mind since it is inexpensive. Any ideas would be greatly appreciated.

Again, the sentamental value of this coin is very high to me.
Thanks

How long did you soak it? Some people soak coins for months to get all the gunk off.

Goo-gone is supposed to work ok.

I soaked for 24 hours or so.Should I go longer?
Goo be gone is safe ?

You need to soak them longer in olive oil

It dosen't work over night

Here is a old thread on goo-gone.

I would give the olive oil more time first though. Maybe swish the coin around once a day to get whatever loosens up off.

melikecoins and placid- thanks that was an excellent thread!! I will be patient with the olive oil and than consider goo be gone if necessary!
Thanks

I have left some coins in the oil for over a month. I also have no problem touching the coins surface while still in the oil if it is a circulated piece.

Make sure to change out your olive oil every couple weeks. I left some coins in some for too long once and it really got ugly looking.

The stuff does go bad after a while.
