I recall old posts about Verdi-gone, and photos of the success some members have had with it.
I see this Verdi-Care Coin Conservation Fluid is now on the market, via Wizard Coin Supply.
Just wondering if it is as good, better, or not as good as the Verdi-gone which I guess was a predecessor.

I just picked up some at the CSNS show I hope to test it this week!
Ill post before and after images as I try it out.
I could not get it to do anything, was disappointed, but it was cheap so no big deal.
Best, SH
I have not seen it yet.... will get some and try it... @spacehayduke ...if it did not do anything, are you sure (honest inquiry, not intending to impugn your knowledge) it was just verdigris? Cheers, RickO
I have a bottle. I tried it a few times but no miracles occurred, so now it is sitting on the shelf with the Nic-o-date, Deller's Darkener, and other miscellaneous coin voodoo and witchcraft potions that I've accumulated over many years haha.

I used a product called Verdi-Gone- not sure if it's the same. It did seem to have a positive effect on some coins. I did forget about an XF 1925-S RPM cent I intended to soak for 30 minutes and it went overnight. It's now a horrible tan color- my fault, not theirs.
It's the same product, just a new name.
It served its purpose, for me, several times. I don't think it's very effective on old verdigris.

I have used it. It is back on the shelf as in my experience there are cheaper, better, and faster products for conservation. I will say this, it seems to be very mild and does not leave a greasy look.
Its maker, a chemist, seems to be pretty knowledgeable. He posts in another forum where most love the product in spite of my experience using it.
i had so so experience with the old stuff. i would hope that this might be the new and improved.
Thanks everyone for your responses.
Lance - was your example soft, or hard and crusty? Since you don't think its very effective on old verdigris, I suspect your example was still soft.
Insider2 - what other better products would you recommend? I already have the 'original' Blue Ribbon, which works fine on surface dirt, haze, and light crust, but doesn't seem to touch real verdigris.
This subject is too complicated for quick answer that will only help some readers to ruin coins.. There are companies like NCS that started up for this.
Nevertheless, any soft green comes off with a soak in Verdi-Care, Blue Ribbon or Care. Acetone is a good follow-up. I do the work under a stereo microscope. In some cases a wood splinter + chemical is faster. Hard green corrosion is a different animal. MS-70 is also good to use for many problems. Practice on junk coins first or take a conservation class and then practice.
I experimented with junk copper a few times. My sense was that newer, softer verdigris was more easily treatable than old, hard verdigris I encountered on large cents.
The verdigris in the example above was relatively soft and flakey. The verdigris on the below Lincoln was older and harder but still was treated successfully.

I think I just learned how to post images...Yea!
This is a pinpoint (spot conservation) dirt removal (25X) done with no chemicals when you don't wish to change anything on a coin. This type of cleaning is not commercially cost effective. LOL. Don't try this at home as you can put a fresh microscopic scratch on the surface. For a larger job use an ultrasonic with distilled water. One problem w/dirt removal is it may leave the underlying surface "off-color." This was not the case here.
Honestly don't remember. It was advertised to remove gunk so I bought it to remove gunk and it did not. Maybe I used it wrong for all I know.
Best, SH
