The hypothesis could be: "Citrus fruit juice will clean the penny the best, due to its high acidity content."
Acids typically clean a penny best because they can dissolve the tarnish (copper oxide) effectively. Bases, on the other hand, may not be as effective in cleaning pennies due to their different chemical reactions with copper oxide.
A combination of vinegar and salt, or a paste of baking soda and water, can help clean a penny by removing dirt and tarnish. Gently rubbing the penny with either of these solutions can improve its appearance.
Dish soap is more effective at cleaning a penny than water alone. Dish soap can break down oils and dirt on the surface of the penny, allowing for a more thorough cleaning compared to just using water.
A mixture of vinegar and salt is effective in cleaning a penny quickly. The vinegar acts as an acid to remove the tarnish, while the salt provides abrasion to help scrub away dirt and grime. Just let the penny soak in the solution for a few minutes, then rinse it off with water.
