Grape juice contains a weak acid called citric acid, which can help break down the tarnish on the surface of the penny. This acid dissolves the copper oxide layer, revealing the shiny copper underneath. Other acids in grape juice, like tartaric acid, may also contribute to the cleaning process.
Lemon juice is the best resource for cleaning a penny as it contains citric acid, which has strong cleaning properties. Lime and orange juice may also work due to their acidic nature, but lemon juice is more commonly used for this purpose.
Vinegar, ketchup, lemon juice, and baking soda are substances that can effectively clean a dirty penny. Each of these substances contains acids or other compounds that can help break down the dirt and grime on the surface of the penny, restoring its shine.
