I mention before we did three trials of this experiment and I noticed that the orange juice gave the pennies a cleaning effect on all three trials. The vinegar seems to give the pennies a hard on trial #3 after 24 hours.

The time it took for these pennies to show a cleaning effect on all three trials was 24 hours based on the types of liquids that were being used.
The variables we kept the same on all trials were greenish-blue pennies are made out of copper. Simply Orange Juice and the white...
