<p>[QUOTE="Drusus, post: 411398, member: 6370"]I think the agent in the olive oil that cleans is the many different fat acids like Palmitic, Myristic, Arachidic, and so on...dont think it would be listed in the ingredients but I never looked...acid in most olive oils that do not say virgin or extra virgin, I believe is 1.5% (regular refined) and .6% to .8% in extra virgin. I would go for the virgin (2%) or standard olive oil and not extra virgin. Some will say use extra virgin but I have tried both and there is little difference in the time it takes and affect between the two. I Doubt brand matters. I always just look for 100% olive oil or regular 'virgin' though 'extra virgin' would be the least acidic if that is a concern for you.</p><p> </p><p>One thing I would also say is before dipping it in oil, try a longer soak in Distilled water or even boiling the coin in distilled water...often times that works well...</p><p> </p><p>Also mineral oil is good for cleaning and it doesnt contain acids.</p><p> </p><p>If you are going with olive oil, remember that you will need to remove it once you are done, this cant be done right with just water...you will need a batch of TSP (Tri-Sodium Phosphate). This is available in most home improvement stores and paint departments. One teaspoon in warm water. Put the coins in the TSP solution for 5-10 minutes. You could use a mild grease cutting dish soap as well but like has been said here often...you dont know what else is in there that might effect the coin.[/QUOTE]</p><p><br /></p>

One thing I would also say is before dipping it in oil, try a longer soak in Distilled water or even boiling the coin in distilled water...often times that works well... Also mineral oil is good for cleaning and it doesnt contain acids.
