Will apple cider vinegar clean a copper penny better than white vinegar?

Yes. Apple cider vinegar is a better cleaning agent than white vinegar for removing tarnish from copper pennies because it contains more acetic acid. Acetic acid is the chemical that actually does the cleaning, so the higher the concentration of acetic acid, the better the cleaning results will be. Apple cider vinegar typically has a concentration of 5-6% acetic acid, while white vinegar usually has a concentration of only 4-5%. This may seem like a small difference, but it can actually make a big difference in cleaning effectiveness, especially for stubborn stains. In addition, apple cider vinegar is also a natural cleaning agent, meaning it is less harsh and more environmentally friendly than some commercial cleaning products. Therefore, apple cider vinegar is the best choice for cleaning copper pennies.
