Vinegar is a common household item that can be used for various purposes, including cleaning and polishing. One of the commonly heard claims about vinegar is that it can make pennies shiny. This claim, for the most part, is true, but the extent to which it works depends on the condition of the penny itself and the concentration of the vinegar.
When exposed to air over time, copper, the metal that makes up pennies, can develop a layer of tarnish. This tarnish can make the penny look dull or dirty. Vinegar contains acetic acid, which can help break down this tarnish and remove it from the penny’s surface. When the penny is soaked in vinegar, the acetic acid reacts with the copper oxide that is responsible for the discoloration and removes it, revealing the shiny copper underneath.
However, the effectiveness of vinegar in making pennies shiny depends on various factors. The concentration of the vinegar is one of the key factors that determine the results. Typically, vinegar that is at least 5% acetic acid concentration will work for pennies. Using vinegar that is more concentrated can provide quicker results but can also be harsh on the penny and cause it to corrode.
Another factor that can influence the effectiveness of vinegar in making pennies shiny is the condition of the penny itself. If the penny is severely corroded or damaged, the vinegar may not be enough to restore its shine. In such cases, additional methods may be required to achieve the desired result.
Vinegar can make pennies shiny by removing the tarnish from their surface. However, the effectiveness of this method depends on several factors, and results may vary depending on the condition of the penny and the concentration of the vinegar used.
Will vinegar shine a penny?
Vinegar can indeed shine a penny. Pennies are made of copper, and copper tends to tarnish over time due to exposure to air and moisture. The brownish coloration that results from this can be removed with an acid, which vinegar happens to be. The acetic acid in vinegar acts as a mild corrosive, helping to dissolve the copper tarnish and reveal the shiny surface beneath.
To use vinegar to shine a penny, you can simply pour enough vinegar into a bowl or cup to submerge the penny, then let it sit for a few minutes. The exact amount of time needed will depend on the severity of tarnish, but usually just a few minutes is enough. You can then take the penny out and gently scrub it with a soft-bristled brush or cloth.
It’s important not to rub too hard, as this can scratch the surface of the penny and make the problem worse. Once you’ve scrubbed the penny, rinse it with clean water and dry it with a cloth to reveal the shiny, gleaming surface below.
It should be noted that while vinegar is effective at cleaning pennies, it is not advisable to use it on other metals or surfaces, as it can be too strong and cause damage. In addition, vinegar should not be used on valuable or collectible coins, as cleaning can reduce their value. For these coins, it is best to leave them as they are or have them professionally cleaned.
How long does it take to clean a penny with vinegar?
The process of cleaning a penny with vinegar can take anywhere from a few minutes to several hours, depending on the level of tarnish or oxidation on the penny’s surface. Vinegar is an acid that reacts with the copper in the penny, dissolving any dirt or grime that has built up on the surface.
To clean a penny with vinegar, you will need a container to hold the vinegar, a small amount of vinegar, and the penny that you would like to clean. To begin, pour the vinegar into your container and then place the penny into the vinegar. Allow it to sit for several minutes, making sure the penny is fully submerged in the vinegar.
After a few minutes, you can remove the penny from the vinegar and rinse it clean with water, which will remove any remaining vinegar residue. At this point, you can gently rub the penny with a soft cloth to remove any remaining dirt or grime.
However, if the penny is heavily oxidized, it may take several hours or even days for the vinegar to dissolve the buildup on the surface of the penny. In some cases, multiple soakings in vinegar may be necessary to fully clean the penny.
The amount of time it takes to clean a penny with vinegar depends on the level of tarnish or oxidation on the penny’s surface, and could take anywhere from a few minutes to several hours, or even days. It is important to note that while vinegar can successfully clean copper coins, it should not be used on valuable or rare coins, as it can cause damage to the metal.
What happens if you leave pennies in vinegar for too long?
If you leave pennies in vinegar for too long, the pennies will become dull and discolored. This is because vinegar is an acid that reacts with the copper in the penny, causing a chemical reaction that results in the formation of copper acetate. Copper acetate is a greenish-blue compound that covers the surface of the penny, causing it to lose its shine and luster.
Over time, if left in vinegar for too long, the penny will begin to corrode, which means the copper will react with the oxygen in the air, forming copper oxide. This will cause the penny to turn green and eventually disintegrate completely.
It is important to note that this chemical reaction only occurs if the penny is made of copper. Modern-day pennies are actually made of zinc, with a thin layer of copper plating. Therefore, leaving these pennies in vinegar for too long may not have the same effect.
Leaving pennies in vinegar for too long can cause the pennies to become dull, discolored, and eventually corroded. Therefore, it is not recommended to leave pennies in vinegar for an extended period of time.
Will vinegar damage coins?
Vinegar is a mild acid that can be used as a cleaning agent for various surfaces, including coins. However, the use of vinegar on coins should be approached with caution as it can potentially damage them.
If you are using vinegar to clean coins, it is recommended to dilute it with water to a very mild level. If the vinegar is too strong, it can cause the metal to corrode or tarnish, which can permanently damage the coin’s surface.
Moreover, vinegar can also dissolve some of the metal on the coin’s surface, which can cause them to lose their original luster and can also make them more prone to scratches.
Furthermore, vinegars can cause toning or change the patina of the coin’s surface. While some collectors appreciate the unique coloring that toning can add to a coin, others prefer preserving a coin’s original surface.
Vinegar can be used for cleaning coins but it should be done with extreme care and in very minimal amounts. If you’re unsure about using vinegar to clean your coins, it is recommended to seek professional advice or to use a different cleaning agent altogether. It’s essential to protect the integrity and value of your coin collection.

Why do coins turn green in vinegar?
When coins come in contact with vinegar or other acidic substances, they start to develop a greenish layer on their surface. This is primarily because the copper molecules present in the coins react with the acetic acid present in the vinegar solution.
Copper is a metal that is highly reactive and sensitive to its surrounding environment. When copper comes in contact with an acidic substance like vinegar, it begins to oxidize, releasing electrons and forming a copper acetate compound. Copper acetate, also known as verdigris, is the greenish layer that forms on the coins.
Verdigris is a natural patina that forms on copper and brass objects over time due to exposure to air, water, and other elements. However, when coins are exposed to vinegar or other acidic substances, the verdigris formation is accelerated, leading to the rapid formation of a green layer on the coins.
This green layer not only changes the appearance of the coins but also affects their value in certain cases.
While the green layer may not be harmful to the coins themselves, it is not recommended to use vinegar or any other acidic substances to clean coins. This can lead to further damage and discoloration of the coins. If you want to restore the shine and appearance of old and dirty coins, it is best to seek the advice of a professional coin dealer or numismatist who can guide you on the proper cleaning and restoration techniques.
Coins turn green in vinegar due to the reaction between the copper present in the coins and acetic acid present in the vinegar solution. This reaction leads to the formation of copper acetate or verdigris, which is the green layer seen on the coins. While the green layer may not be harmful to the coins, it is not recommended to use vinegar or any other acidic substance to clean coins as this can lead to further damage and discoloration.
