I have followed many of the cleaning topics for some time and I finally decided to try to see what Olive Oil would do for a coin.
I placed an assortment of non valuable dirty coins in Olive Oil and let them soak for a month.
I then rinsed them with purified water.
Now I have some older non valuable coins that are still dirty and feel slippery to the touch.
Will you experienced "coin cleaners" tell me where this experiment went wrong.
I think I will continue the mantra - NEVER CLEAN A COIN.

Hi Richard
Which coins did you put in the oil ?
Olive oil is a treatment for copper and bronze ,, and depending on what is on the coin can take several months,, it is this gentle long term properties of olive oil that make it what it is .
By the way were talking extra virgin and changed every week or so !!

I tried using it to clean some dug up coins, but all I ended up with was some dirty, oily coins.

I use a vibrating tumbler and pecan shells for the dug coins I'm going to spend  Rick |

Appearently olive oil gives pretty interesting results. You should resin them out with acetone or something, or light detergent or some sort to get rid of the oily surfaces.

isn't Crud an Alkali substance?
So shouldnt you use an Acidic Substance like Citric Acid or Lemon Juice?

citric acid will discolor the copper coin and make it a sort of pink color.. But I dont doubt its ability to eat at the crud ... On FORVUM a forum for ancints they recomend Didtilled water Long soaks, I mean long soaks. And same as metalman said .. The best qulaity Olive oil you can get Like EXTRA,EXtra virgin olive Oil(EXpensive kind) and soak for a long time water will get rid of the olive oil with Light blotting. (all though it is never recommended)..

Olive oil, as I understand it, is used on copper, bronze and other verdigris-prone alloys to stop badly corroded and verdigrized coins from getting worse. I understand that it slowly soaks into the "green death", softening it and making it easier to remove. You usually still need to physically scrape away at the affected areas. This thread contains my limited experience with olive oil. So far, it's slow progress, but I'm prepared to be patient. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
