Testing the Verdi-care Process by a beginner

Here are my first attempts to use the Verdi-Care product.

Before:







"Here's the steps you should take....first....be VERY careful, you don't want to chemically damage the coin worse than it already is.

1) Soak in distilled water for 10 minutes (both sides). This step will remove any water soluble residues that may be on the surface.

2) Get some high grade acetone from the hardware store or a lab supply store. DO NOT USE FINGER NAIL POLISH REMOVER. The ingredient should be only acetone on the label, no additives. Soak it for one minute in acetone (each side) using a GLASS container. Acetone will melt plastic. Search the forum for acetone if you want to learn more about using it.

3) Allow the surfaces to fully dry. It should only take a few seconds for the acetone to dry and dehydrate the surface. I used canned air for speeding up this step. A few gentle shots on each side will do the job."







"4) Using glass container, put the coin in and cover it with VC. Allow it to soak for one hour then flip the coin and soak the other side for an hour. Note: You can use your finger to flip it....VERDI-CARE™ is 100% safe on skin.

5) Remove the coin, pat gently with a coin-safe towel (I like micro fiber towels). Let it dry for 24 hours (both sides) and check the progress. Post a picture here so we can determine what the next step to take is.

The coins are currently being soaked in Verdi-Care for 1 hour on each side. I will post the results when completed.

This is perhaps a better look at results.

Very interesting....

'53 seems to have been helped out considerably...
The stains on the back of the '91 D is a bit... discomforting.
Minimal effect on the 1940, from what I can see.

 

Not too bad. I'm having similiar results with my tests.

I'm pretty impressed what i've seen so far, though there is some discoloration on some of my test subjects, which i guess can be expected when it comes to heavy corrosion.

Nice pictures btw ^^

 

Thanks for sharing your results. May I suggest following up the soaking with the micro fiber towel method?

That is due to the lighting. VC will not stain. I'm sure Marshall can clarify.

 

The lighting in combination with the coin still being wet (even after the micro fibre towel drying) has made it more reflective of the black velvet background. These are follow up pictures with lighting at 180 degrees from the prior photos with 9 hours of drying.







Also, to be fair, these coins do not represent light to moderate verdigris and my take repeated treatments. Of course I defer to comments by BadThad.

 

So what exactly is Verdi care made of? Is it just a cheap chemical bottled up and sold at the price of 5 gallons worth, or is it more than that?

 

First I believe there is a patent on it so you probably won't get an answer for that. Second I do not think it is that expensive.

 

I can see why the first two coins didn't clean up. But why didn't the 1940 clean up much?

 

My understanding is that it's Verdi-care, not verdi-cure. It stops the spread of the verdigris, without removing what would damage the coin.

 

If you look at the bottom right of the reverse of the 1940, you'll see it working well on the light verdigris. It appears to still be working since it's improved after 9 hours after the initial soaking was completed.

I was a little disappointed that an instruction booklet didn't come with the product which for some reason I expected. But BadThad will pop in and keep me on the road to proper use.

To me, the jury's still out on the Zincoln. Something had caused the discolorization to spread on to what was Lincolns nose and forehead where there was red before. It sort of has the effect of throwing a non colorfast red towel in with the whites.

 

So, Verdi-cure will remove the green?

 

I bought some from Wizard, but haven't used it yet. If you go to their site, somewhere in the Verdi-care link is a link to how to use instuctions.

 

the green on that coin looks likes its stained into the coin(from a newbie perspective anyway), which if thats the case i dont think verdi-care will remove it.

I had success removing a significant amount of verdigras on one coin, except a little bit of a stain along the rim on the reverse,. Ill put some pictures up tonight when i get home of my test subjects.

I'm pretty impressed on how well its working, if you follow the instructions right. Just dont except too much from heavily corroded coins. As thad said on another website, its intended to remove light to somewhat moderate verdigras, and in those situations, it works wonders(at least so far), not to mention to halt further corrosion

 

I appreciate your candor. I'd ask the same question myself of any chemical product because there's been so many scammers to do just that sort of thing.

I am a metalworking fluid chemist and a numismatist and I developed my initial product VERDI-GONE™ (and later VC) out of frustration with all the classic surface residue removal options. VERDI-CARE™ is a proprietary, formulated blend of highly pure (yet safe) laboratory-grade chemicals.

 

Wizard Coin Supply provides all of the product documentation on their website. Also, as you said, I'm on the forums frequently and I'm happy to answer questions.

I have seen some pretty drastic discoloration happen on zinc cents from exposure to acetone. If the coin was not soaked in distilled water prior to the acetone bath, it can even cause artificial rainbow toning.

 

I didn't mean to make it come off as expensive. It's a good price. I'll probably buy some next time I make an order from wizards. Also, on the count that you are a chemist, would recommend one of your products or acetone for removal of PVC damage on Ike dollars? I have a whole album of them.
