Another great way to clean pennies is to use a solution of vinegar and salt. Fill a cup about 1/4 of vinegar and a teaspoon of salt (more salt, faster reaction). The tarnish that forms on a penny is copper oxide. The salt and vinegar create an acid solution that causes the copper oxide to dissolve off the coins. Once they are clean they should have their original shiny coat. Remember though, if there are pits in the pennies they will show now that the oxide has been removed. If you don't have vinegar any acid such as lemon juice or Coke/Pepsi will work as well.HOWEVER ....Cleaning an ordinary modern penny is fine because there are so many of them. But you should NEVER, EVER try to clean a collectible coin because anything you have at home will damage the coin's surface and reduce or even destroy its value to another collector.
Ordinary white vinegar is a dilute form of acetic acid. Because it's acidic, it reacts with the oxidized copper that forms on the coin's surface.
Of course, if you have a coin that's worth a premium as a collectible, you should NEVER try to clean it at home because anything you have - vinegar, soda, Tarn-X, whatever- will damage the coin's surface and reduce its value.

Clean it, to eliminate what? Grease and oil? 409. Cuprous or Cupric Oxide? Salt and vinegar.
Because ketchup has acid.
Vinegar, yes, but not ketchup. Vinegar cleans it because it is an acid. Actually, the best thing to use is cola or lemonade and leave the penny in some cola or lemonade for 48 hours - it normally does the trick!
yes, the penny will be shiny if you cleaned it with vinegar
It's simply a chemical reaction of acetic acid and copper. It doesn't have a specific inventor.
Vinegar contains Acetic acid that reacts with the copper in the penny.
I think it's vinegar.
The vinegar was so strong that it clean the penny. Vinegar is acedic acid. The penny has oxidized in air and the acid removes the oxidization from the penny, making the copper shiny again.
The penny will get clean i did that in science class and in less than 2 minutes the penny became clean
the salt will dissolve in the vinegar and the penny will get really clean well if it dirty
If you have any tarnished pennies in your penny jar, you can easily clean them in vinegar. If you leave your pennies in white vinegar and salt for about 30 minutes and they will come out shiny and pretty clean. Be sure to rinse the vinegar off.
vinegar has an acid in it that dissolves microscopic particles only found on certain matals.
White vinegar does a fine job.
Vinegar is acid.. Soda is sugar and carbonation.
