How To Clean Coins

Cleaning coins is not an easy task. It takes the right materials and the ability to clean coins properly. This blog post will assist you in cleaning your coins. We will talk about which material is best for cleaning what dirt and how to do it.

We'll also discuss how to keep your coins safe from dirt, dust, and other debris after they're cleaned.

A simple task that you can do at home is to clean coins. You might need to use different techniques depending on the material. You will find some examples of cleaning techniques and images of the before and after results for several metals common to U.S. coins.

Remove any dirt or debris by using a soft toothbrush, old cotton strips, or your hands. If you find stubborn stains stuck to the copper, you can gently rub them off using fine steel wool (#0000). After brushing all surfaces, rinse them under warm water. Then rub the pieces firmly between your fingertips.

The next step is drying the coins well and removing any moisture. Finally, use a soft cloth to polish each currency. Use the cloth to gently remove any raised areas. Your results will come eventually. It might take some effort. Alternate cleaning solutions include toothpaste and baking soda mixed with water. It is important to not scrub the metal too hard, as this can cause damage to both sides.

People who are just starting to clean their coins often wonder if there are any chemicals they should avoid. The following chemicals can cause damage to both the metal itself and your health.

These chemicals can cause coins to corrode, so avoid using ammonia or chlorine bleach. Other harsh acids, like vinegar, muriatic (pool grade), hydrochloric and other products can also harm metals. It's best to avoid these as well. While it might take more effort, you'll get a better end result and avoid any potential dangers.

Other organic options work well for copper-alloy pieces such as Indian pennies. They include lemon juice mixed together with water, baking soda, and white vinegar. White distilled white vinegar is the best choice, as it does not contain any harmful chemicals. This can be used to remove stains on copper coins without damaging them. Another option for cleaning pennies is to use toothpaste (gel varieties work best), on a soft towel, or mix warm water and table salt. It will remove any stubborn dirt. A little elbow grease may be required though.

These techniques can be used to remove most tarnish marks quickly. You can also get rid of any other blemishes that may have remained on your coin's surfaces after they have been cleaned up. If the problem persists after you've tried other methods, you might want to consult an expert who is knowledgeable about rare coins.

If you know what to do and have the correct supplies, cleaning coins can be a rewarding activity at home. You can reverse corrosion damage if it doesn’t get too deep into the metal or in crevices surrounding raised markings. Oil-like stains can sometimes be seen on older pieces. But these issues can often be resolved quickly by using any of many techniques. It is important to avoid using any harsh cleaners such as acid-based cleaners or bleach when you try new solutions. These could cause damage to the coin's surfaces. We wish you all the best in your collecting endeavors!

How to clean coins: Use fine steel wool #0000 to brush them off until they are gone.

After brushing all surfaces clean, thoroughly rinse under warm water. Rub the coin between your fingers. The next step is drying the coins and removing any moisture.

  • Put your coins in vinegar for 24 hours. This will remove any corrosion or black tarnish from your cash. You can use one quart of regular distilled vinegar with a teaspoon of salt to remove more dirt and corrosion. If you don’t have any vinegar, you can use lemon juice. However it won’t be as effective at removing stubborn spots from pennies.
  • Be sure to rinse the sponge with warm water and dry it completely. Combine the baking powder/soda with a bowl of water. Mix it until you have a paste.
  • With an old toothbrush, apply the baking powder mixture. Don't scrub the surface. Apply the baking soda mixture in a circular motion to avoid scratching the metal.
  • You can use vinegar to clean the brushes. Wait 24 hours before soaking the coins again in vinegar solution. When the soak time is done, dry the coins completely. If you intend to store them later, place them in an open container.
  • You can use toothpaste or baking soda paste to further clean up the surface if you are unsure. If that doesn't work, then you might need fine 0000 steel wool to finish the cleaning. This will help to remove stubborn rust deposits and prevent further damage from occurring if the coin is left unhandled. You should be very careful because this could cause damage to the coins.
  • Continue the same procedure to the second penny side if necessary. Once you have completed the first side, dry both sides thoroughly before storing them in an enclosed container. When you return to working with these pennies, avoid touching other surfaces.
  • To keep your pennies separated from other coins, seal the container. You can also store your pennies in paper sleeves, if you don’t own any airtight containers.


  • Let the silver dollars soak for at least 24hrs before using a toothbrush to scrub them. This will help remove dirt and corrosion from the surface. You can either mix regular baking soda into the water or use dishwashing soap to make a thick frosting-like mixture. If necessary, add more salt to your mixture.
  • The mixture should be applied with a toothbrush on the coin's surface. Do not remove any designs or details that are visible on the back side of the cash. Let the paste dry completely before using it. It will be able to clean the surfaces without further damage. A hairdryer can speed up the drying process. Don't touch the coins again until you are ready to clean them. Make sure to dry each coin on both sides before placing it in the sealed container.
  • The best way to clean silver coins that are dull and tarnished is to soak them overnight in milk. This will remove any stains from the coin's sides.
