 I am a twelve year old girl and I am doing this project for our school Science Fair . I would like to use this as an addition to my poster as added research. Which juice cleans pennies the best? I have done the experiment with lemon juice, cranberry juice, white grape, and apple juice. Apple was far and above the best. I learned that acid levels have nothing to do with getting the pennies the cleanest or cleaning them the fastest. Thanks, Sha-Aute' P.
What are you talking about -- lemon juice works the best. Joseph L.

i think lemon juice will work better because it has Citric Acid [link is to product info at Amazon] and because of its sourness

I tried lemon, apple, tomato, orange and grape juice and my findings were that grape juice cleaned the best. But when we investigated further, we added salt to the lemon juice and within 5 minutes the oxidation was gone and the penny was much shinier.

October 26, 2009 Hi, students. Juices that are most acidic will probably work best because you are dissolving the tarnish into the acid. Although most juices don't have much salt in them, salt is also very powerful at dissolving corrosion products. I would be very curious about the apple juice that Sha-Auté used and the grape juice that Tyler used. Did you by any chance look at the ingredients list and see if sodium or salt were added to those juices? We have an FAQ: What Cleans Pennies Best that should answer all of your questions about this project, and help you do the experiment well. Good luck! Regards,
