Testing the Verdi-care Process by a beginner

PVC residue is best addressed with pure acetone.

Should I just repeat this procedure for the hard cases or do something different?

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.

I actually found the improvement to the 1940 pretty amazing. If I were putting together a collection from circulation I would definitely want the Cared for coin.
One a side note, I do not think it is a very good idea to used canned air due to the residue that it can actually release. That has been my experience while building and cleaning numerous personal computers. I would just set the coin on edge and let it air dry since acetone evaporates so quickly.

 

I use pure acetone for all my pvc damage, but is verdicare safe for nickels as well as cents. I have a couple of nickels that have some verdigris on them.

 

For the best results, use that procedure. However, I've conserved many coins with direct application (no prep) too. Just keep experimenting and you'll quickly learn what's best on a given coin.

 

This is going to come off sounding like a bad infomercial, but I'm presently a Verdi-Care believer.

Back when it first came out as Verdi-Gone I bought a couple of bottles, tried it out, and didn't get any satisfying results. It wasn't very impressive at all actually... maybe I got a bad batch.

When I found out it was re-branded and the formula had changed somewhat, I decided to give it another go as I had some coins I really needed to treat. I'm really glad I did!

I had a copper nickel coin that had a tiny amount of verdigris marring an otherwise perfect coin, and I didn't know what to do. I don't "clean" my coins, so I wasn't going to try anything beyond a little xylene and acetone and a little prod with a soaked toothpick. The verdigris would NOT move.

After soaking in Verdi-Care for a couple of days, a gentle prod removed most of the verdigris and a soak for another couple of days removed the rest all by itself. Of course, there is a tiny pit left where the verdigris was eating away at the coin, but at least I stopped the destruction of the coin and removed the unsightly green speck.

I wish I had taken some before and after pics, but I didn't. To be honest, based on my experience with Verdi-Gone I wasn't even sure if it was even going to work. The spot was so small I probably would have had to use a high-end macro lens anyway. As it was, I needed a 20x loupe just to see the area clearly.

Anyway, just wanted to say, thanks Thad!

 

These are the same coins after sitting for 5 months without further treatment. This should show redidual effects.
