There was a recent thread about a Dremel meeting a Indian head penny. Check the results, you will not place a Dremel so close to a coin ever again.
You appear to be serious. I really hope you know it was supposed to be funny. You know a thing called a joke.

Goo-Gone, elbow grease, and a supply of toothpicks will remove a lot of gunk and most verdigris, but be prepared for a lighter-colored coin under gunk.
Now that one isn't supposed to be funny, maybe. Hopefully no one really tries that. May as well go back to a Dremel.

how about olive oil immersion for 20 days? I tried that with copper coins but just couldnt wait for the 30days, went and cleaned with soft toothbrush after 1 week. the copper coins were ok, the green gunk is gone but some of the black stain still remained. overall I would rate 10-15% better looking than before
Actually I've heard that if really bad coins are left in Olive Oil for several thousand years the corrosion will come off. I'd try that one but not sure I could wait more than a few hundred years.
And of course you do realize that not all Olive Oils are the same so which type, brand, purity, origin, etc are you suggesting?
Why not just suggest battery Acid. I know that would work and very little left of the coins to complain about.

Ketchup does work, but it will completely strip the coin. They may get "red-looking," but will have absolutely no mint luster, and have a dull shine. I've used it on a few ugly copper lincolns, and have decided that it's not worth it. It MIGHT be worth it on a foreign coin, just to bring out an interesting design.
