Ok, so I know that Olive Oil is an effective cleaner for Ancients. I have been using it for crusty Roman Bronzes and it's worked well so far.
I was wondering if anyone has tried it on modern coins yet?
I have a couple of coins mainly 19th century silver US & World coins who could use a nice long soak. Any possible adverse effects of soaking Silver coins in Olive Oil for a few days? There is no surface contamination (No Dirt, oil, PVC etc.) but most of them are toned over so there may be some sort of chemicals contributing to the toning.
I use only Extra Virgin Olive Oil. Just looking to soak for a day or two (Or possibly longer) and a wash with distilled water afterwards.
Thoughts?

Olive oil is slightly acidic, and that is the reason I guess, why it is effective in the cleaning of ancient bronze coins.
Although I have never cleaned a modern coin with olive oil, I would imagine that modern bronze coins would tend to darken due to it's acidic property.
I believe that the oily property of olive oil would also useful in softening and loosening hard to remove substances from the surface of a bronze coin.

Just remember that when you remove STUFF from a coin, you normally also remove some of the coin's original metal. Olive oils and many other substances are used by so many and they seldom realize just how much of the coin they also removed. Why not just use battery acid. Same results.

The olive oil works much more slowly allowing for the process to be monitored and provides the opportunity to lessen the amount of damage done. Actually battery acid can be made to be all sorts of concentrations. And too, depending on how long an exposure of a coin to such solutions, could be controlled just as well as Olive Oils, Tomato juices and all the other types of cleaners. And if the battery acid is purchased new, it is rather clear. No contaminates. |

Dilute lemon juice and vinegar are also used in the cleaning of ancient coins recovered from burial.
It is well worth a 'survey search' of the 'Net, to review all of the methods that museums use in the recovery and restoration of ancient coins.
