My project is an expansion of the Taco Sauce Penny cleaner experiment. The acid and salt in the taco sauce reacts with the oxide on the penny to clean it. I tested the different variables of this experiment, namely the oxidized/tarnished metal, the acid and the type of salt. For the metals, I tested silver, copper, iron and pennies; for the acids I tested lemon juice, orange juice, cola, tomato juice and apple juice; for the salts I tested sea and table salt.
