this what I do olive oil week or longer then acetone

 

Acetone can be bought at a hardware store, but you must get pure acetone, not something with additives like polish remover.

Having said that, acetone will not, by itself, remove verdegris if that is what you mean by corrosion.

 

Acetone can be bought at any hardware or paint store. I've used it to clean tape glue off of silver coins but have no idea how it reacts with copper.

thanks i probrably still pick some up to use on some silver that my uncle put tape on and will only try the acetone on a cheap total corroded penny so i dont damage ( turn wierd) nicer ones

 

Wait, hang on. Try mineral spirits. It's very gentle but desolves duct tape adhisive and tar from cars without any discoloring. It is a lot,lot safer than acetone. Give the MS time to disolve the tape or adhesive without rubbing much. zg

 

I don't think olive oil is a good idea.

 

Acetone will not help with corroded copper.

 

copper is fussy and will be ruined very easily

Without experience and perfect technique, cleaning copper almost never ends well. {a corroded coin cannot be made un-corroded} If you can post a good photograph & description of the problem, then you might get some good advice at CT.

My advice: If the copper coin is worth $50 or more, then have it conserved by a professional like NCS.

Very best regards,

Good advice above. zg

 

I bought sme acetone and used it on a peace dollar that had all this black gunk on it (i bought the coin for ten bucks) and it got rid of all the gunk but didn't harm the coin it still has some dark toning but now I think this is the nicest peace dollar I own

 

Is mineral oil the same thing? And where do you get that stuff from, Walgreens?

 

Mineral spirits and mineral oil are two different things. Mineral spirits is paint thinner.

 

You can get it at Home Depot, Lowes, or a hardware store. It works well on removing adhesives, disolves them, like old duct tape after the coin sets awhile. Copper, though, is affected by just about anything. Experiment on some coin that have been abused to see how both acetone and min eral spirits work.
I think you did the right thing in using acetone since it seemed to have done the job as you described. zg
