The 5 coins in question:  Reasons for some sort of conservation: ->the 1910 is sticky ->the rest feel filmy and grimy, and dont slide over each other. Reasons I want to use Acetone: No means to buy verdicare online. Plan: 1) set up a table on my concrete driveway for a work surface. 2) wear nitril gloves to wear. 3) Put the coins, one at a time, into (stainless bowl/sealed mason jar?) then pour in the acetone. 4) Ligtly swish container or manipulate coin with my hand for a minute. 5) After a wash and rinse cycle, place coin on torn up t-shirt. 6) 2x2 the coin. |

My input (await others' as well):
1) If you've a garage, set up in there (door open). You're not going to be handling sufficient quantity to make for any vapor danger and I'd rather see you keep this out of direct sunlight if possible.
2) Nitrile good, latex (real latex) better, either acceptable. You may note damage on the nitrile if you end up handling all the coins, probably not until the end of the session. Acetone won't harm bare skin unless you have a damaged cuticle or a sore, in which case it'll hurt like....a lot. Use gloves anyway.
3) For what you're doing, something like a baby food jar would be ideal. Prefer glass to SS for less chance of harm to the coin.
4) Swish the coin on its' own; if you hold it, you'll be covering areas the acetone needs to touch.
5) Wash and rinse cycle is in a second, clean acetone solution. Acetone evaporates completely, and anything further is redundant. They'll be dry before they touch the t-shirt.
Your plan is good, you're describing symptoms the acetone should handle. I think the 1930 might require a formal soak for an hour or so; I may be wrong.

i removed the oil in this coin few minutes ago just using the cotton stick and acetone , you can see the right side of the coin is clean... what I do is move in circles with almost no pressure and wet all the time, I don;t use gloves... oh make sure to use 100 % acetone, NO cosmetic...  |

Have plenty of ventilation when using acetone. Use real acetone not nail polish remover - they are similar but not the same. If you ever have to use water use distilled water and let the coins dry properly before putting away.
Regards, marked man

A solution of baking soda and water will do the same without the acetone on those modern issues.

Don't understand what the paranoia is about acetone. Out of all the solvents it is one of the safer ones you can use,after water for the human body. It is safer than paint thinner which is a mixture of some common and some nasty solvents. Mineral spirits is worse for the human body. Turpentine is down right nasty.
According to the book Artist Beware by Micheal McCann Phd.CIH
the relative toxicity rating is Skin contact: slight, Inhalation: slight, and Ingestion: moderate. It also has a good odor warning meaning smell. You have something located in the middle of the face that tells you to get your face out of the way when you smell something!
You have to use uncommon sense if you aren't removing finger nail polish and you will be exposing your pinkies to the acetone use nitrile, vinyl or other solvent proof gloves. Yes it flammable the hazardous materials field guide, states its Autoignition temperature is 961°F , Flash point is 103°F @ a vapor density of 2.1 Don't use it around open flames or while smoking!
If you are uncomfortable in using it in your house then by all means use it out side. Although most women would laugh at some of the things that have been posted on this forum. I understand some people can really get their knickers tied in a knot if they don't have any understanding or knowledge of things.
Acetone is safe to have in the house, use in the house. if you take minimum steps to mitigate any of the possible problems.
Just to for stall the smart one what are you a chemist!
I will answer that no I am not, I have been a craftsperson in the special effects field, sign painter for over 25 years, using lead paint for all that time, and some of the now banned solvents in Cali on a daily basis. Among other trades that use solvents and chemicals.
I took an interest in the materials I use, I make sure I have the proper equipment when I'm using it. Lucky I can say I am not suffering form any of things that constant and long term exposure to these materials, can result in.

You said precisely why I don't like acetone. It's flammable, has a low flash point and can cause respiratory damage. Nail polish remover (even the "100% acetone" stuff) is diluted. When I had acetone in my lab I had to keep it in the flammables locker and use it under a ventilation hood. I prefer to use the least toxic material for the job. Here's a link for the MSDS (Material Safety Data Sheet) for Acetone for all who are interested http://fscimage.fishersci.com/msds/00140.htm |

Never go directly to acetone! ALWAYS start with distilled water for ANY conservation project. I recommend the solvent polarity ladder, move the next solvent if the previous one is ineffective: 1) water 2) acetone 3) xylene Quote:

The worst exposure is for women sitting in a bathroom (or worse yet a car) using it. Soaking some coins in a sealed, glass container is completely safe. There's no need to even use gloves. Acetone is a very low level hazard as long as there are no open flames around. Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

I've handled most of my Indian Head cents with my bare hands and now am worried about long term storage and body acids. Would a quick dip in Acetone fix this problem? And, are cotton liners okay for future handling? |

I rinse almost all my coins with acetone prior to storage. It's a good, general practice to remove light debris and oils IMO.
