How to Clean Coins

It is difficult to clean coins. Cleaning coins requires the right materials and knowledge to properly get their value. This blog post will guide you through the process of cleaning coins. We'll discuss which type of material you need to clean and which techniques are best for different types of dirt.

We will also discuss how to store your coins once they have been cleaned, so they are protected from dirt and other debris.

It is easy to clean coins at home. You may need different methods depending on the material. This article will provide information on some of the most common cleaning methods, as well as images of before-and after results for various metals found in U.S. coins.

First, clean the surface of any dirt or other debris using a soft toothbrush, cotton swabs or your hands. (Be sure to wear gloves when handling copper). If you have stubborn stains that are stuck to the metal, gently scrub them with fine steel wool (#0000). After brushing, rinse all surfaces under warm water and rub it between your fingers.

Next, dry the coins completely and then remove any moisture using a paper towel. You will then buff the currency with a soft cloth. Be sure to remove any raised design areas. Although it may take some time, the end result will be well worth it. You can also use toothpaste or baking soda mixed in water to clean the area. You should not rub the metal too hard as this can scratch the surface of the coin.

Many people are curious about whether there are any chemicals that should not be used when cleaning coins. These chemicals are harmful to the metal as well as your health.

For cleaning coins, you should not use chlorine bleach, ammonia, or any other chemical containing these chemicals. They will cause the coins to corrode. Some products, such as vinegar, hydrochloric acid (pool grade), and muriatic acid (pool-grade), can also cause metals to corrode. Although it may be more difficult, you will get a better result without having to use anything dangerous.

Some organic solutions can also be used on copper-alloy items, such as Indian head pennies. These include lemon juice mixed with water, baking soda, or white vinegar. White distilled vinegar, which does not contain harmful chemicals, is a good choice to remove copper coins from stains. You can also clean pennies with toothpaste (gel or powder) using a soft cloth, warm water and table salt. However, it will take some elbow grease.

These techniques will quickly remove most tarnish marks from coins. You can consult an expert who specializes in rare coins if you still have problems.

Cleaning coins at home is a fun activity if you are familiar with the process and have the right supplies. As long as corrosion hasn't eaten too much or gone too deep in any crevices around the raised marks, it can usually be reversed. Older pieces may have oil-like stains that are difficult to remove. However, these issues can be quickly fixed using one of the many techniques available. You should avoid using harsh chemicals such as bleach or acid-based cleaners, which could damage the coin's surface. Good luck with your collection!

Cleaning Coins: Cleaning Methods for Dirty Coins

You can clean coins with fine steel wool (#0000), until they disappear.

After cleaning all surfaces, rinse them under warm water and rub the pieces between your fingers. Next, dry the coins completely and then remove any moisture. You will then buff the currency with a soft cloth. Be sure to remove any raised design areas. Although it may take some time, the end result will be well worth it. You can also use toothpaste or baking soda mixed in water to clean your surfaces. You should not rub metal too hard as this can cause more damage.


  • For 24 hours, soak your coin in vinegar. This will get rid of the corrosion and black tarnish on your money. To draw out dirt and corrosion, you can use one bottle of apple cider vinegar or white vinegar. If you don't want to use vinegar, lemon juice is an alternative. However, it is less effective in removing any heavy spots from your pennies than this method.
  • After soaking, rinse off any remaining wetness with warm water. Dry completely before adding baking soda paste. This could lead to more spotting when we clean everything with a toothbrush. Mix the baking powder and soda in a bowl with water.
  • Use an old toothbrush to apply the baking soda mixture. Be careful not to scratch the surface of the coin. To avoid scratching the metal, use a gentle circular motion.
  • For the next step, use vinegar again. It will remove any remaining dirt and corrosion after brushing. Allow coins to soak in the vinegar solution for another 24 hours until any tarnish is gone. If you plan to store them elsewhere, let them dry completely after the soaking period is over.
  • To get rid of any lingering details, you might try baking soda paste or toothpaste. For your final cleaning, you may need to use fine 0000 stainless steel wool. This will remove any stubborn rust deposits that may have accumulated over time. This last step can cause scratches to coins so be careful!
  • If necessary, repeat the process on the other side of the penny. Make sure that both sides are completely dry before you store them in an airtight container. Keep your pennies from touching any surfaces until you are ready to start working on them again.
  • Keep your pennies organized and separate from other coins in a sealed container If you don't have an airtight container, you can store them in paper coin sleeves.


  • Before you scrub silver dollars with a toothbrush, soak them for at least 24 hours. This will allow the dirt and corrosion to be removed from the surface. After the soak is complete, let them dry completely before applying the paste. Mix regular baking soda with water until you get a thick, white mixture that looks almost like frosting. If you need more salt, you can add more salt as before.
  • Use a toothbrush to apply the paste to the coin's surface. Be careful not to scratch any designs or details on the cash front. To ensure that the paste works effectively, it should dry completely before you start scrubbing. You can speed up drying the paste by using a hairdryer to fanne off. Do not touch any areas until the next time you clean coins. Dirt and residue can easily transfer to them when they are handled. Before storing any coin, dry both sides thoroughly.
  • If silver coins appear dull or tarnished from age, you can clean them by placing them in milk overnight. This will remove any stains on either side of the coin.
