Prepping my first crusties. I have done a week in distilled water and was gonna go to olive oil next but decided to try murphy as an in between step since it is sort in the middle in terms of solubility. Anyone ever try that?

No, however some of the most surprising things to "clean" coins are in drug and grocery stores. It just takes lots of time, money, and junk coins to experiment with to learn which work and which do not. New products are being made every year and I confess to be about a decade behind anyone trying the new stuff!
One of the best copper cleaning chemicals was discovered this way over twenty years ago. Oh, I already forgot what it is :(

I have not heard of it being used to clean ancient coins. Unless you know what the chemical make up of the product is I would not recommend using it.

Murphy's Oil/Soap
The main ingredient is potassium soap manufactured from vegetable oil also sodium EDTA, propylene glycol and water.
I would be leary of using this.
I do not know what the acronym EDTA is.

Hey guys. Isn't it frowned upon to "clean" coins? I heard that. Is it true or a certain method of cleaning? Thanks

What I think is being discussed is cleaning literally hundreds of years of grime off ancient coins. Someone who actually collects them (I don't) will have to confirm, but I think that cleaning is more acceptable and sometimes necessary for ancients than it is for, say, US coins. |

Ancient/medieval coins (this is the ancients forum) = they usually need to be cleaned because when they are found (usually in the ground or as part of a hoard) they are often dirty and need to be (properly) cleaned so they can be identified. So basically, cleaning is perfectly acceptable in the field of ancient/medieval coins when required. |

I do not know what the acronym EDTA is. EDTA is Ethylenediaminetetraacetic acid. I'm not a chemist, but on the interwebs there seems to be general consensus that it bonds to metals and helps to separate non-metallic compounds from metals. In terms of uses for MOS, according to wikipedia: Quote:
It is also commonly used to clean black-powder weapons after use, since the lack of petroleum-based oil and the presence of vegetable oil lessens the amount of sludge that is created when cleaning black powder residues from weapons. It has also been found to efficiently remove the black powder residue that builds up on automobile wheels and hubcaps from the disc brakes. @thunderpaste, I might leave that bottle of MOS out in your garage or under your sink and proceed with a little more caution.

Thanks. A few years ago I bought one of those 'uncleaned Roman coins' lots. I IDed a few LRB pieces as well as a Latin imitative, but everything else is pretty crusty. I think I'll try olive oil.

I am partial to using olive oil. One drawback is that it does tend to darken the coin.
