Penetrating oil?
« on: December 18, 2015, 07:52:21 pm »
Anyone ever tried using a penetrating oil to get under the dirt?  I was just toying with the idea of using some of my CLP (Gun Oil), it's fantastic at removing carbon deposits, would it work as well on coins?  Would it hurt the patina?

Olive oil, that's the stuff to use.

I really don't know how weapon oil would behave when used to clean coins. I ain't so sure it's an good idea, because it is petroleum based and neither do I think it is a good idea to use some solvent based bore cleaning agent.

I have used penetrating oil, gun oil in fact, as part of the process of cleaning large iron objects (horse-shoes, spurs, etc).  I would not do it for coins.  Wrong chemistry - you are not removing carbon deposits from coins.  I think the oil would react negatively to the coin.  It would certainly make further cleaning a pain.
