Mineral Oil to Clean Large Cents?

[Metdet49]

I hate to bring up yet another cleaning question, but does anyone have any experience with soaking coins in mineral oil to help clean coins? In particular I would like to know if this is a good way to clean non key date copper large cents. Supposedly it is better than using olive oil in that it doesn't darken the coin as much. I don't want to do any damage to the coins, but I want to loosen some of the crud to gently remove with a cue tip or toothpick to hopefully reveal more detail.

I know you have to be careful with cleaning any coin and some coins you shouldn't clean at all, but I am hoping to find a good, non invasive way to make the coins more displayable.

Thanks.

If you absolutely Must clean a coin, especially a corroded copper, then I've found that a heavy duty penetrating oil like Kroil will do the job IF you allow the coin to soak long enough. The Kroil will remove the corrosion and that will cause pitting on copper or most any coin that is corroded. But if you must then you must...........................63bkpkr

Kroil will do a good to clean up with. "the oil that creeps". Lol. That's the bad part about the old coppers that have been in the ground for years they just have to about be cleaned for the most part with something. But I sure have to see people cleaning on silver coins.
