What's the best way and/or the easiest way to remove years of hardened dirt off of coins to make them look at least some what new and clean?

I need and want on know what's the best way and/or the easiest way to remove years of hardened dirt off of coins to make them look at least some what new and clean?

Please give me details with a source or 2 with your answers, if any of you can! That'd be very greatly appreciated. A source or 2 with each and every answer isn't exactly needed, but it's so very preferred.

    I recommend Twinkle copper cleaner. Very effective.

    If they're collectible coins - of any value due to age and scarcity - DON'T clean them.

    However, if you must, according to cleanipedia, you can soak them in white vinegar for 30 minutes (or even over night).

    I have no source, other than my brain, but I'd soak them in peroxide.

    Leave in a glass of Coca Cola overnight. No source it's been around for decades.
