Cleaning Corroded Pennies

I found some old pennies that are all green and corroded. Does anyone know how to clean them up?

I heard that soaking them in a batch of Alka Seltzer would get that off. I'm not sure though. (11/13/2008)

Use ketchup. It works wonders. I've also heard soaking in Pepsi or Coke will work, too. (11/13/2008)

Vinegar will clean them. We tried it in school long ago and I still remember it made them look like new. (11/13/2008)

Coins like furniture reduce in value if cleaned, so if you think they may be worth something, check with a coin dealer before cleaning. (11/14/2008)

I've used baking soda and lemon juice, but anything acidic would work. I agree to check with a coin dealer if you think they may be valuable. (11/15/2008)

Pennies can soak in a vinegar and salt solution. Then wipe clean. Have fun with your penny collection. (11/15/2008)

Baking soda is not acidic, so don't use that if you are looking for an acid solution. I don't know about Alka Seltzer, but I'll bet that it is. Ketchup, vinegar, lemon juice those are all acids.

I used Louisiana Hot Sauce, left it for a short time (5 min.) and it wiped right off. (11/18/2008)
