Default Which type of juice cleans a dirty penny the best?

My child must do a science fair project on "Which juice cleans a dirty penny the best? This is a first grade project. How many different kinds of juice must be used, and how long are the pennies supposed to soak?
Thank You

Default Juicy Juice

I would say soak them for 24-48hrs. I did a project like this in 2nd grade. You should use at least 5 different juices each with different contents. For example, one water based, one that isn't.
