Coin Cleaning, He-Man Style

Link. Something for everyone here:
"I soak my silver in Silent Green for a day (or two if real stained) then I scrub them with a Brass Brush- I know, you're not supposed to do this- but brass is softer than our coins and they come out great. Try it-you'll like it."
"I have found that EDGE gel is great on golden colored coins with an aluminum alloy."
"I found a well worn Standing Liberty quarter that was stained and I used silver polish (just hand rubbed with a piece of paper towel). It came out clean and shiny."
"I know I read this recipe on one of the forums a while back, and I've used it on Indian head pennies with great results. Use a half-n-half mixture of Clorox cleanup with vinegar."
"I use simple green lightly diluted in my tumbler with my aggregate being beach sand to clean my "black" clad before it is rolled and taken to the bank. Stuff really works great!"
"I'll tell you my 'secret' way to clean coins. I use green Palmolive dishwashing soap. ***This can take up to a month *** Never be in a hurry to clean anything you find. I've killed several good coins like this. Let the coins soak in the soap. Every now and then remove them and scrub with a toothbrush and replace. Add soap as needed as the soap evaporates. (This method takes time.) I've got some Buffalo's soaking right now and they are starting to shine! When they come out they will be "eye catchers" as the dates are still on them. Try it on some Jeff. nickels and see."
"I've had good luck on silver with a 24 to 48 hr soak in Simple Green (from your supermarket) and then brushing them with a brass brush. Please, if one of those coins is worth 300 Bucks-don't do it!"
(All right, so he's pulling coins up from the ground. Still damn funny to read the marked difference between collectors here and, well, "ordinary" collectors. And I'll bet he's blown out at least a couple coins that could have been salvaged.)

<< <i>I find that if you treat the surfaces with a power sander, you can restore the coin to the way it looked before those pesky dies hit it... and a bath in boiling nitric acid is sure to get rid of stains, toning, dirt, the obverse, the reverse, and the edges! And here's my SUPER SECRET trick to get rid of fingerprints: smash the coin with a sledgehammer to evenly distribute the fingerprint over the surface, heat it to 600 degrees Celsius, and while it's hot, pour gasoline on it to burn those fingerprints right off! Don't be stingy on the gasoline; the more the better... >>

Silent Green? Does he mean Simple Green again or has he misspelled Soylent Green? That's about the only substance this guy hasn't tried.
And mas3cf, I think your cleaning methods are safer than those presented on the web site.
Sequitur, that's a riot.

Not surprising. Check the ingredients and you will probably find that high on the list is vinegar = acetic acid. Acetic acid + Copper coin = copper acetate which I believe is water soluable. Basicly it simply etched away the surface of the coin leaving a fresh surface.

PS I guess I should mention these were coins I had found metal detecting. It cleaned them up enough to spend or put in rolls to cash in at the bank.

When I was five or six years old, I got ahold of a couple large cents my grandfather had, I shined them up really brightly, by rubbing them of the sidewalk. Boy did they shine. Boy did I get the tar kicked out of me. (figuratively speaking ).
