Goo Gone copper experiment

jesbroken

In no way did I even consider that Goo Gone would restore a damaged coin. This was just an experiment to
see how well it handled verdigris on copper. The damage to this coin was heavy, as was the verdigris. This
experiment lasted 2 hours and I changed the fluid at one hour. I utilized a cotton swab lightly, but an afterthought
brought me to realize the damage to this coin could not be increased by cotton hairlines.
I think I will try this on a better condition coin with verdigris just to better see the outcome.
Hopefully this is interesting to you.

Nice. The pitting remains but the goo be gone.

Nice results!

Definitely got rid of the green....I may need to try that myself.

Thanks for sharing!

Does it still smell? At a show a while back I was taking a look at a BU Franky and could smell Goo Gone on it....I'll pass.

Perhaps the person using it did not use soap and water to rinse it after application.
I followed instructions and can only smell copper.
Let me be clear, I in no way have any affiliation with Goo Gone. A friend of mine
said it would work on removing verdigris on copper coins without damaging the surface or changing
its color. I decided to try it on a coin with no real value. I believe that she is correct regarding
the verdigris removal. Until I try it on a better condition coin, I won't know regarding the surface
condition or color changes upon use.
Thanks all for your comments.

I think you should submit it to our hosts for their opinion. The results look very good, but will it pass their sniff test?

I'd like to see this tried on a dug coin. Copper that has been underground usually comes out pretty rough.

I've used Goo-Gone once or twice, but I'd say you had particularly good results, there.

Other than acetone and olive oil, I've not tried much. I do have a couple old copper medals with the dreaded verdigris...monetarily they are not 'worth' a professional conservation, but maybe this can help. Is there a specific type of goo gone? My quick Google shows a variety of types.

The coin would still genny anyway, due to environmental damage....and as has been stated other times, not every coin gets
the sniffer test - I think its only performed on request, or at certain levels of certification. And if given an acetone treatment after
the Goo Gone, then a thorough rinse, I doubt the sniffer would detect anything anyway. I believe its designed more to pick up
things deliberately left on the surface, like putty.

I would not care to have our hosts sniffer test any low value coin as
my sniffer works fine. Now if it is for a $1k plus coin, maybe.

I used Goo Gone on a quarter eagle that had been glued into a book. It worked fine and didn't damage the coin at all. I figured that since I was working with gold, there was not much chance that I would do any damage.

Although I have tried many chemicals on coins, I have not tried GooGone... interesting results. As long as you use good neutralizing/cleaning steps afterwards, it should not give problems 'down the road'. Thanks... Cheers, RickO

I was curious as to the ingredients and I found this MSDS (Material Safety Data Sheet).
