Pennies can get dirty and discolored over time from normal wear and tear. If you have a jar full of pennies that have lost their shine and luster, don’t worry – with some white vinegar, you can clean pennies easily and make them look brand new again!
Vinegar is a mild acid that reacts with the copper oxide on the surface of pennies to dissolve away tarnish and restore shine.
If you’re short on time, here’s a quick answer to your question: Submerge dirty pennies in a bowl with undiluted white vinegar for 1-2 hours. Then, take them out, rinse off the vinegar, and dry them thoroughly.
The acetic acid in the vinegar will dissolve copper oxide on the pennies’ surface and make them shiny again.
In this comprehensive guide, we’ll cover everything you need to know about cleaning pennies with vinegar. We’ll discuss why pennies get dirty, why vinegar works so well, the step-by-step process, useful tips to get best results, and how to store cleaned pennies so they stay shiny longer.
Why Do Pennies Get Dirty and Discolored?
Have you ever wondered why pennies lose their shine and become dirty over time? There are a few factors that contribute to the discoloration and dirtiness of pennies. Understanding these factors can help you better care for your coins and keep them looking their best.
Exposure to Air and Moisture
One of the main reasons pennies become dirty and discolored is their exposure to air and moisture. Over time, pennies oxidize and develop a layer of copper oxide on their surface. This oxide layer gives the penny a dull and dirty appearance.
When pennies are exposed to moist or humid environments, the oxidation process is accelerated, leading to even more discoloration.
According to experts at the U.S. Mint, the copper in pennies reacts with the oxygen in the air, creating copper oxide. This process is known as oxidation and is responsible for the brownish discoloration seen on old pennies.
The longer a penny is exposed to air and moisture, the more pronounced this discoloration becomes.
Handling Wear and Tear
Another reason why pennies get dirty and discolored is due to regular handling. When we handle coins, the natural oils and dirt from our hands transfer onto the surface of the penny. This can lead to a buildup of grime and dirt over time, making the penny appear dirty and dull.
Additionally, the friction caused by handling the penny can also wear away the outer layer of metal, exposing the underlying copper. This can further contribute to the discoloration and dullness of the penny.
It’s important to note that the dirt and discoloration on pennies is purely cosmetic and does not affect their value as legal tender. However, if you’re interested in restoring the shine and luster of your pennies, there are various cleaning methods you can try, such as using vinegar.
Why Use Vinegar to Clean Pennies?
When it comes to cleaning pennies, using vinegar is a popular and effective method. This household ingredient can bring back the shine and luster to dull and tarnished pennies. But why exactly is vinegar the go-to solution for cleaning pennies? Let’s explore the reasons below:
Acetic Acid in Vinegar Dissolves Copper Oxide
Vinegar contains acetic acid, which is a mild acid that can dissolve the copper oxide that forms on the surface of pennies over time. Copper oxide is the main culprit behind the dull appearance of pennies, and by using vinegar, you can effectively remove this layer of oxide and reveal the shiny copper underneath.
The acetic acid in vinegar acts as a natural cleaning agent, breaking down the tarnish and restoring the penny’s original shine.
Vinegar is Non-Toxic and Safe
Another reason why vinegar is a popular choice for cleaning pennies is its non-toxic and safe nature. Unlike harsh chemicals or abrasive cleaners, vinegar is a natural and gentle option that won’t harm your skin or the environment.
It is a much safer alternative, especially if you have children or pets around. So, you can clean your pennies without worrying about any harmful effects.
Simple Household Ingredient You Likely Already Have
One of the best things about using vinegar to clean pennies is that it is a simple household ingredient that you likely already have in your kitchen. Vinegar can be found in most homes, making it a convenient and cost-effective solution for cleaning your pennies.
It saves you from having to purchase specialized cleaners or chemicals specifically for cleaning coins. Just grab a bottle of vinegar, and you’re ready to go!

Step-by-Step Guide to Cleaning Pennies with Vinegar
Before you begin cleaning your pennies with vinegar, it’s important to gather all the necessary materials. You will need:
- A small bowl or container
- A soft-bristled toothbrush
- A towel or cloth for drying
Having these materials ready will make the cleaning process much easier and more efficient.
Make Vinegar Cleaning Solution
The next step is to create the vinegar cleaning solution. Simply pour enough vinegar into the bowl or container to fully submerge the pennies you want to clean. You can use either white vinegar or apple cider vinegar, as both work effectively.
Fun fact: Vinegar is a weak acetic acid that can dissolve the tarnish on pennies, revealing their original shine. It’s a safe and natural cleaning agent!
Submerge Pennies in Vinegar
Now it’s time to submerge the pennies in the vinegar cleaning solution. Place the pennies gently into the bowl or container, making sure they are fully covered by the vinegar. Allow them to soak for about 5-10 minutes.
Tip: You can use a toothpick to gently agitate the pennies in the solution to help remove any stubborn tarnish.
Rinse and Dry Pennies
After the soaking time is up, remove the pennies from the vinegar solution and rinse them thoroughly under running water. Make sure to remove any vinegar residue from the pennies.
Once rinsed, pat the pennies dry with a towel or cloth. Avoid rubbing them too vigorously, as this can cause scratching.
Store Properly to Maintain Shine
Finally, to keep your freshly cleaned pennies looking their best, it’s important to store them properly. Oxidation and tarnish can still occur over time, so it’s best to keep them in airtight containers or coin holders.
Pro tip: Avoid touching the surface of the pennies with your fingers as much as possible, as the natural oils on your skin can cause them to tarnish more quickly.
Now that you have the step-by-step guide to cleaning pennies with vinegar, you can easily restore their shine and add a touch of brightness to your coin collection or craft projects!
Tips and Tricks for Best Results
Use White Distilled Vinegar
When it comes to cleaning pennies, using white distilled vinegar is key. This type of vinegar contains acetic acid, which is highly effective at breaking down the grime and tarnish that can accumulate on pennies over time.
It’s important to use white distilled vinegar specifically, as other types of vinegar may not provide the same level of cleaning power.
Pro Tip: Don’t have white distilled vinegar on hand? You can easily find it at your local grocery store or order it online.
Soak for 1-2 Hours
Once you have your white distilled vinegar, the next step is to soak your pennies in it. Fill a bowl or a cup with enough vinegar to fully submerge the pennies. Allow them to soak for about 1-2 hours. This timeframe gives the vinegar enough time to work its magic and break down the dirt and grime on the pennies’ surface.
Pro Tip: If you’re cleaning a large number of pennies, you can use a larger container or even a plastic bag to hold the vinegar and pennies. Just make sure the container is sealed tightly to prevent any leaks.
Scrub With Soft-Bristled Toothbrush
After the soaking period, it’s time to give the pennies a gentle scrub. Using a soft-bristled toothbrush, gently rub the surface of each penny to remove any remaining dirt or tarnish. Be careful not to scrub too hard, as this could potentially damage the pennies.
Pro Tip: If you don’t have a soft-bristled toothbrush, you can also use a cloth or a sponge to gently scrub the pennies.
Lay Pennies in Single Layer to Dry
Once the pennies have been cleaned, it’s important to let them dry properly. Lay them out in a single layer on a clean towel or a soft cloth. Avoid stacking the pennies on top of each other, as this can cause moisture to get trapped between them and potentially lead to further tarnishing.
Pro Tip: For faster drying, you can also use a hairdryer on the lowest heat setting to gently dry the pennies.
By following these tips and tricks, you’ll be able to effectively clean your pennies using vinegar. Remember to handle the pennies with care and enjoy the satisfaction of seeing them restored to their former shine!
Storing Cleaned Pennies
After you’ve successfully cleaned your pennies using vinegar, it’s important to store them properly to prevent them from tarnishing again. Here are a few tips on how to store your cleaned pennies:
Place in Air-Tight Container
One of the best ways to store cleaned pennies is to place them in an air-tight container. This helps to keep out moisture and other elements that can cause tarnishing. You can use small plastic containers or coin holders specifically designed for storing coins.
Make sure the container is clean and dry before placing your pennies inside.
Use Silica Gel Packets
Silica gel packets are commonly found in packaging and are used to absorb moisture. These packets can be very helpful in preventing tarnishing of your cleaned pennies. Simply place a silica gel packet inside the container along with your pennies.
The silica gel will help absorb any moisture in the container, keeping your pennies dry and tarnish-free.
Store in a Cool, Dry Area
It’s important to store your cleaned pennies in a cool and dry area. Heat and humidity can accelerate the tarnishing process, so it’s best to avoid storing your pennies in places like the bathroom or near windows.
Instead, find a cool and dry spot, such as a drawer or a cabinet, where you can safely store your pennies.
By following these simple storage tips, you can keep your cleaned pennies looking shiny and bright for years to come.
With just some white vinegar and a little time and elbow grease, you can make worn and dirty pennies look shiny and new again. Vinegar’s acetic acid dissolves away copper oxide tarnish through a chemical reaction.
Follow the steps to soak pennies in vinegar, scrub if needed, rinse, and dry thoroughly. With proper storage, your cleaned pennies will keep their luster. Know that this penny cleaning method can restore shine but won’t increase any numismatic value.
