Mark on My 1883-O Morgan, what to do ?

Sorry, I would've made it shorter, but I didn't have the time.

If the coin is not dried properly (It's not the bath). And letting the contaminated acetone dry all be itself on the coin just leaves a film, ah more and different "skin" as some wish to call it. [/QUOTE]
do you rinse with distilled water and pat dry. I read about that ?

Yes. Either distilled water and pat dry or better yet, I usually rinse in fresh acetone poured straight from the quart jar on the coin like a waterfall over the sink as I'm holding the coin by the rims. Then no pat drying is even needed, just hold the coin for about 15 seconds and the acetone fully evaporates

 

Again as I have read in other posts once the coin is pulled out of the acetone can't it be rinsed in distilled water then pat it dry ?

 

No, you just ensure the last acetone rinse is of an uncontaminated coin. Whatever liquid you use on the coin - water, acetone, goat's milk - you don't stop rinsing until there's no contaminants left on the coin.

Acetone is so volatile it evaporates in a couple seconds without the need to "pat dry," and I've no idea why people advocate drying it. You have to move fast to get something onto the coin at all to dry it after acetone.

Please, just listen to jeffB, who knows what he's doing.

 

NO !!!!!!!

 

Distilled water can be used as a final rinse but fresh acetone as I described above is a much better final rinse.

Feta Morgan's dave?

Acetone leaving a "skin"...NO NO NO. If it is clean, it leaves NOTHING. As far as rinsing with distilled water, if there is some acetone on the coin carrying any contaminant, the water will cause the contaminant to come out (precipitate) and leave you in worse shape than you started. Final word...if you rinse, finish the job.

 

What is the best way to dispose of used acetone?
Thanks,
Steve

 

Down the drain

 

Flush with LOTS of water, please. I'd rather not have flammable vapors accumulating in my stand-pipes, and I'd be a bit nervous about what acetone was doing to PVC drain pipes.

 

I can see you don't know or follow SOP. If you only knew what some places must go through to dispose of chemicals... Or else $$$$$.

 

That is a *REALLY* bad idea.

Most modern homes have pipes made of PVC, or similar plastics. The whole point of using acetone on our coins is to dissolve PVC, or similar organics.

Ergo, dumping acetone down the drain sounds like a really good way to get a really high plumbing bill.

Acetone is quite volatile - place the container of used acetone outside in a well ventilated area, away from open flames, and out of reach of kids or pets. It will evaporate away quite quickly.

 

It might be slightly more environmentally friendly to burn it off outside. It'll evaporate quickly, but drop a lit match into it and it will evaporate a lot more quickly. (That's what I actually did the last time I did an acetone run. Use a metal can for the burning.)

 

Let's see...do I want to pollute the water or the air...hmmmm...decisions, decisions

 

Depending on the quantity involved, I either let it evaporate outdoors or burn it.

 

I was told to use "used" bath acetone for its intended purpose... collect it into an empty acetone can, write on the can "USED COIN WASTE" and "PAINT ONLY"... then use it for painting related things.

 

What kind of painting would one use acetone for? Or is it for cleaning paint brushes? Or cleaning paint spills on surfaces that would not be harmed?
