While there are many different ways to clean coins, not all of them are effective. Some methods can even damage your coins, so it’s important to choose the right one. In this article, we will discuss how to wash dirty coins using a simple and effective method that will not harm your coins.
Before you start cleaning your coins, it’s important to gather the necessary supplies. You will need:
– A bowl of warm water
– A mild dish soap
– A soft brush

Once you have gathered your supplies, you can begin cleaning your coins. First, soak your coins in the bowl of warm water for a few minutes. This will help to loosen any dirt or grime that may be on the coins. Next, add a few drops of dish soap to the water and gently scrub the coins with the soft brush. Be careful not to scrub too hard, as this could damage the coins. Finally, rinse the coins thoroughly with clean water and pat them dry with the clean towel.
Preparing the Cleaning Solution
The first step in cleaning your dirty coins is to prepare the cleaning solution. There are a few different recipes that you can use, but the most common and effective is a mixture of white vinegar and water.
To make the cleaning solution, simply combine 1 part white vinegar with 2 parts water in a bowl or container. You can also add a few drops of dish soap to the solution to help remove any grease or grime from the coins.
Once the cleaning solution is prepared, you can start cleaning your coins. To do this, simply soak the coins in the solution for a few minutes. The length of time will depend on how dirty the coins are. Once the coins have soaked, use a soft cloth or brush to gently scrub away any remaining dirt or grime.
After the coins have been cleaned, rinse them thoroughly with water and pat them dry with a clean towel. Your coins should now be clean and shiny!
Tips for Preparing the Cleaning Solution

Cleaning Silver Coins
Silver coins can tarnish and become dull over time. To clean them, you can use a variety of methods, depending on the severity of the tarnish.
Mild Tarnish
For mild tarnish, you can use a soft cloth and a mild dish soap. Gently rub the coin in a circular motion until the tarnish is removed. Rinse the coin thoroughly with water and pat it dry with a soft cloth.
Moderate Tarnish
For moderate tarnish, you can use a silver polish. Apply a small amount of polish to a soft cloth and rub the coin in a circular motion. Rinse the coin thoroughly with water and pat it dry with a soft cloth.
Heavy Tarnish
For heavy tarnish, you may need to use a stronger cleaning agent. One option is to use a solution of baking soda and water. Make a paste of baking soda and water and apply it to the coin. Let the paste sit for 10-15 minutes, then scrub the coin gently with a soft brush. Rinse the coin thoroughly with water and pat it dry with a soft cloth.
Other Methods
There are a number of other methods you can use to clean silver coins. Some of these methods are more effective than others, and some may be more appropriate for certain types of coins. Here is a table summarizing some of the most common methods:
| Method | Effectiveness | Suitability |
|---|---|---|
| Soft cloth and mild dish soap | Mild | All coins |
| Silver polish | Moderate | Most coins |

| Vinegar and salt | Moderate | Tarnished coins |
| Lemon juice and salt | Mild | Lightly tarnished coins |
Cleaning Gold Coins
Gold coins are valuable and delicate, so it’s important to clean them carefully. The gentlest method is to soak them in a solution of warm water and mild soap, then rinse them thoroughly and pat them dry with a soft cloth.
If the coins are very dirty, you may need to use a more aggressive cleaning method. However, avoid using harsh chemicals or abrasive cleaners, as these can damage the coins.
One effective way to clean gold coins is to use a jewelry cleaner. These cleaners are designed to be gentle on delicate metals, and they can remove dirt and grime without damaging the coins.
Another option is to use a baking soda paste. To make the paste, mix baking soda with a small amount of water until it forms a thick paste. Apply the paste to the coins and let it sit for a few minutes. Then, rinse the coins thoroughly and pat them dry with a soft cloth.
If the coins are still dirty after using a jewelry cleaner or baking soda paste, you may need to use a stronger cleaning solution. However, it’s important to test the solution on a small area of the coin first to make sure it doesn’t damage the metal.
| Cleaning Solution | Instructions |
|---|---|
| Vinegar | Soak the coins in vinegar for a few minutes, then rinse them thoroughly and pat them dry with a soft cloth. |

Once the coins are clean, it’s important to protect them from future tarnishing. You can do this by storing them in a cool, dry place in a sealed container.
