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!
Clean it, to eliminate what? Grease and oil? 409. Cuprous or Cupric Oxide? Salt and vinegar.
To clean any penny, try using ketchup and a toothbrush. After that, make a paste out of baking soda and water then lightly rubbing the penny with your thumb. For even better results, try using an eraser. Any type, it doesn't matter. Your penny should be nice and clean!
i think that ketchup,lemon juice,vinigar,tomato juice is the best
yes, the penny will be shiny if you cleaned it with vinegar
vinegar has an acid in it that dissolves microscopic particles only found on certain matals.
The vinegar and salt in the ketchup will remove most of the dark tarnish on a darkened or dirty copper penny (you can accomplish the same effect more quickly using just a small dish of vinegar and salt). However, the penny will "clean up" with a slightly beige-pink or rosy color, significantly not quite the color of a shiny new penny.

Yes.
Pennies as in coins?? Yep! Cillit bang reckons it can, but coca cola is the best. Just drop them in it and voila! The acid in tomato juice or catsup, or ketchup will do the same thing. If the penny is a collectable, do not clean it as any excess polishing or rubbing on the surface will actually reduce the value of the coin.
If you put a lot of salt in the vinegar it will make lots of dirt come off the pennies
The acids in the Tomato Ketchup took off the dirt and mess on the penny.
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.
