I understand this question has been asked dozens of times, but I need an internet resource on how cleaning a penny works.
I've looked on Yahoo but have yet to find a definitive source.
As an older brother, I'm being forced to work on a project for my brother, so I'd appreciate some help. Any website that I can print out and send to my mother, which is what she wants.

Guys, it's which one of THESE cleans it better, sorry.
I know there are better ones out there, but these are the ones he picked. If it were me, I'd do it. I've done countless science projects, but I refuse to do it for him.
The only compromise I could come up with is finding the information, but I need some scientific evidence, from a website that I can print. Please!

The lime is the most acidic of those fruits, so its juice should clean the penny the quickest, though citric acid alone can't completely dissolve red Copper (I) Oxide, so not a perfect pickling solution for all pennies. Try taking 3% hydrogen peroxide from the drug store and squeeze the lime juice into that. That would make an interesting comparison solution.

The question probably assumes that you will be soaking one penny in lime juice, one penny in lemon juice, and one penny in orange juice for a fixed amount of time. There are a couple of possible approaches: 1)Cut a slot big enough for a penny in each fruit. Allow them to sit overnight (about 12 hours), then check to see which penny is shiniest. 2)Squeeze the juice of each fruit into separate small glasses and place a penny in each. Let sit overnight and see which one is shiniest in the morning.
Between you and me, big brother, my money's on the lemon. Do you know why?
Best of Luck!

Usually we use lemon juice. Baking soda helps too. Orange juice does not clean.

Depends on the acid content, the higher the acid the better it will clean your benny, Not sure which has the most acid though.

Believe it or not a pencil eraser. Have you tried coin cleaners? or cleaning coins? Yeah, type in cleaning coins. My father was a coin collector and he never cleaned coins, it makes them worthless. It's like refinishing an antique,the whole point is to get it like it is.

The best way is mustard.
Yes the type you put on hot dogs, also you can use vinegar.

Tarnex works better than any of those three you asked about.
