Clean pennies expo 

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, cranberry, 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,
