KOINSOLV Ingredients?

KOINSOLV is advertised as a neutral coin solvent that removes PVC, oil, tape, grease, etc., and as an alternative to acetone. The instructions say to swirl the coin then let air dry. The same manufacturer used to produce DISSOLVE, which was primarily triclorotriflouroethane (sp?), an ingredient that was very popular for cleaning, but was banned from public use.
The ingredients listed in KOINSOLV are n-Propyl bromide, 1-Propanol, Oxygenated hydrocarbons, and 1,2-Epoxybutane.
What about these ingredients? What affect do they have on coins?

Some refer to overgraded slabs as Coffins. I like to think of them as Happy Coins.

1-Propanol is an organic alcohol. Oxygenated hydrocarbons may include things like acetic acid, acetone, a variety of ketones, aldehydes, esters, etc. This is the stuff bacteria will utilize as a source of carbon. And, 1,2-Epoxybutane, it is a four carbon compound with an epoxide functional group.
This is just a "super" organic solvent mixture to cover as many bases as possible. There may be "crud" that acetone by itself won't dissolve very readily. The combination of solvents is designed to dissolve as much crud as is possible in a short period of time.
If you use this have two or three containers handy. Let the first function as a soak. Then rinse briefly in the second container before transferring to the third container for a quick dip and swish. Then let the coin air-dry.
Do this procedure in a well-ventilated area (outside?) and don't smoke or work near an open flame. I’m quite sure that the components are volatile AND flammable.

I've not used Koinsolve, I stashed a pretty good quantity of TCTFE before it got banned.

Sounds like KOINSOLV is a broader attack. My takeaway is that if you have a simpler issue, like PVC from a flip, perhaps acetone may be more appropriate. Acetone has not been that good for me. I don't like the effect on some coins, and too many times it has left a hazy look. Maybe it is a result from impure acetone or maybe from bad technique. I've looked for HPLC (high pressure liquid chromatography) grade acetone without success.

Since I can't find the HPLC you tipped me onto, how about some of your TCTFE?!?!?

It worked perfectly and some of the coins were encapsulated by both ANACS and PCGS.
Some of the coins were cleaned (wasn't apparent until after the removal of the PVC) and they were BB'd though.
It worked very well!
The stuff is pretty noxious though....definitely use it outside. Did it in one container to clean it and in another to rinse it, then air dry. After 6 or 8 coins or so...used the rinse one as the clean one and poured a new rinse one. According to the label, the solution can break down and melt some plastics, so the dipping containers I used were the bottom halfs of aluminum soft drink cans that I cut in half. This worked fairly well. When I was all done, I just left the cans outside for the rest of the solvent to evaporate.
it tastes even worse. And It gave
me a headache.
