There are several ways to make pennies shiny again, but the key is to understand what causes pennies to become dull and tarnished. Pennies are made of copper, which reacts with oxygen in the air to form a layer of copper oxide. This oxide layer is what makes pennies dull and brown over time. Therefore, to make pennies shiny again, we need to remove this layer of oxide and clean the pennies properly.
One way to clean pennies is by using acidic substances such as vinegar, lemon juice, or ketchup. These substances contain weak acids that can dissolve the copper oxide layer and restore the shine of pennies. To clean pennies using vinegar, you can create a solution of equal parts white vinegar and water in a small container.
Then, place the pennies in the mixture and let them soak for a few minutes. After soaking, you can use a soft-bristled toothbrush or a cloth to gently scrub the pennies, rinse them with water, and dry them with a towel.
Another way to clean pennies is by using a mixture of salt and vinegar or salt and lemon juice. The salt acts as an abrasive and helps to remove the copper oxide layer while the acidic substance dissolves it. To clean pennies using this method, pour some salt on a plate, and squeeze some lemon juice or vinegar on top of it.
Then, dip the pennies in the mixture and rub them gently using a cloth or a toothbrush. Rinse the pennies with water and dry them with a paper towel.
Alternatively, you can use commercial copper cleaners or polishes to clean pennies. These cleaners contain strong chemicals that can remove the copper oxide layer more effectively but may also damage the pennies if not used properly. Before using these cleaners, read the instructions carefully, and follow them closely.
Some popular copper cleaners include Brasso, Wright’s Copper Cream, and Bar Keepers Friend.
There are several ways to make pennies shiny again, but the most effective methods involve using acidic substances or commercial copper cleaners. It’s important to handle pennies carefully and avoid using harsh chemicals or abrasive materials that can scratch or damage them. With the right approach, you can restore the shine of pennies, making them look as good as new.

Can vinegar damage coins?
Vinegar is a highly acidic solution that can cause significant damage to coins, especially those made of copper or bronze. When copper-based coins come into contact with vinegar, it causes a chemical reaction that can lead to corrosion, discoloration, and the formation of unsightly greenish-blue colored stains known as verdigris.
This reaction is caused by the acetic acid in vinegar, which reacts with the copper to form copper acetate.
Over time, continued exposure to vinegar or other acidic substances can weaken the metal and cause it to become brittle, making it more likely to crack, break, or corrode. This can significantly diminish the value of the coin, making it less valuable to coin collectors or enthusiasts.
In addition to causing physical damage, vinegar can also remove or strip any protective coatings or natural patina that have developed on the coin’s surface over time. These coatings help to prevent further corrosion, so their removal can further damage the coin’s surface and increase the likelihood of future damage.
Therefore, it is not recommended to clean coins with vinegar or any other acidic solution. If you need to clean a coin, it is best to use a mild soap and water solution and gentle, non-abrasive tools or cloths. When handling coins, it is also important to avoid touching them with bare hands, as the oils and acids in our skin can also cause damage over time.
Instead, use gloves or hold the coin by the edges to prevent unnecessary damage.
What happens when you mix vinegar and pennies?
When you mix vinegar and pennies, an interesting chemical reaction takes place. The copper pennies react with the acetic acid present in the vinegar, causing the copper coating on the pennies to dissolve. This creates a murky and cloudy solution that has a blue-green color, which is caused by the formation of copper acetate.
This process is a type of oxidation reaction in which the copper atoms lose electrons, causing them to dissolve in the vinegar.
Moreover, the reaction between vinegar and pennies is often known as the “penny cleaning experiment,” which is popular in elementary schools and is used to demonstrate the power of acids and bases. The cleaning solution is known to work efficiently due to the presence of acetic acid, which dissolves the copper oxide that forms on the pennies’ surface over time when exposed to air, sweat, or other elements in the environment.
As a result, the mixture causes the pennies to become shiny and look as if they are new.
However, it is important to note that although the reaction between vinegar and pennies can make the pennies look shiny and new, it can also cause long-term damage and corrosion. The acid present in vinegar can cause the pennies to become brittle and weak over time, which can lead to cracks, fractures and ultimately render them unusable.
The reaction between vinegar and pennies is a fascinating example of a chemical reaction, where the copper on the pennies reacts with the acetic acid in the vinegar to form copper acetate. This reaction can be used to clean pennies and demonstrate the power of acids and bases, but it can also lead to long-term damage and corrosion, making it important to be cautious when using this method to clean coins.
What happens when pennies are exposed to vinegar?
When pennies are exposed to vinegar, chemical reactions take place that can cause the pennies to change color and texture. The reaction between the acetic acid in the vinegar and the copper in the penny causes a chemical reaction known as oxidization. This process leads to the formation of copper acetate, which forms a thin layer over the surface of the penny.
Initially, when the penny is placed in vinegar, nothing much happens to the surface. However, after a few minutes, the acetic acid in the vinegar starts to dissolve the top layer of copper on the penny. This process is known as copper ionization. As the copper ions dissolve in the vinegar, bubbles form on the surface of the penny, indicating that the reaction is taking place.
Over time, the copper ions form a compound with the acetic acid in the vinegar, producing a greenish-blue substance known as copper acetate. This substance forms a thin film on the surface of the penny, which gives it a greenish-blue hue. If the penny is left in the vinegar solution for a longer period, the copper acetate will continue to form and will eventually cover the entire surface of the penny.
The reaction between the vinegar and the copper in the penny can also cause some other changes. For example, the texture of the penny may become rough or pitted as a result of the chemical reaction. In addition, if the penny is left in the vinegar for too long, the entire surface may become corroded, eventually leading to the penny’s complete disintegration.
When pennies are exposed to vinegar, the acetic acid in the vinegar reacts with the copper in the penny, leading to the formation of copper acetate. This reaction can cause the penny to change color and texture, ultimately leading to its destruction if left in the vinegar for too long.
