How to clean coins? Coins have great value for many people and collectors. Some collector’s coins can have a very high value, so you have to be very careful about cleaning them.
But if you are looking for tips to clean and shine coins you will find several practical tips in this article.
Be careful, it is not recommended to clean a collector’s coin because you risk damaging the surface of the coin and it will thus lose its value.
1. Clean bronze coins
Do you have bronze pieces at home that you want to clean and shine? Well, soapy water is the only possible solution for cleaning bronze.
- Fill a container with hot water and add a little liquid soap.
- Soak the bronze pieces in the solution for about ten minutes.
- Rinse the parts with clean water and dry with a soft cloth (dab the parts).
2. Clean a copper piece
Although hot soapy water can also be used to clean copper there is a more effective trick; the vinegar.
- Boil a little white vinegar and immerse the copper coins.
- Wait for the liquid to cool to remove the coins.
- Allow to air dry on a microfiber cloth.
Do you have collectible aluminum coins at home? Here’s how to successfully clean it:

Add an abrasive powder to the solution to make it even more effective for cleaning.
4. Clean silver coins
Whether cleaning silver coins or objects, it is important to be careful not to scratch and damage the silver surface.
- Dilute a little alcohol in very hot water and soak the silver coins.
- Leave to act for a few minutes, remove them from the solution and dry gently with a soft cloth.
5. Clean a gold coin
Are you a collector and have old gold coins in your collection? As gold is a precious material, it is better to be careful and choose a soft and non-abrasive product to clean and shine this type of piece.
- Pour “very” hot water into a container and add mild liquid soap.
- Soak the gold coins for a few minutes and allow to cool.
- Rinse the gold piece between your fingers with clear water and place the piece on an absorbent paper.
Never use a brush or cloth to scrub, clean and dry a gold coin. You risk damaging the piece and its natural protection.
6. Cleaning cupronickel parts
For those who wish to clean cupronickel, vinegar is also effective for this material. Here’s how:
- Pour into a container of white vinegar and add a little salt.
- Soak the cupro-nickel pieces for a few minutes.
- Remove and place the parts on a paper towel to complete the cleaning.
7. Cleaning zinc parts
Unlike other metals, it is recommended not to clean zinc coins. Indeed, zinc is a material that oxidizes easily, quickly and unfortunately.
In reality, the more you clean the zinc, the faster it oxidizes and unfortunately becomes unrecoverable.
If you absolutely want to clean a piece of zinc then opt only for soapy water, nothing more.
8. Use Marseille soap
Another effective product for cleaning a coin is Marseille soap.
Although this product helps to clean and shine I do not recommend its use on genuine collector’s items.
- Mix Marseille soap with a skin of warm water.
- Scrub the part with a cloth or toothbrush
- Gently clean your coins with a toothbrush and Marseille soap.
This trick should not be tested on a collector’s item because you risk removing the natural patina of the item in addition to scratching it and therefore devaluing it.
