Who does not like a small treasure of coins? But unfortunately, our coins often no longer shine so beautifully. Rather, they are tarnished black and dirty. What is the best way to clean coins?
Let coins shine again
You will need
- Dirty coins
- Small rags or kitchen towels
- Vinegar
- "Cleaning agents” such as crushed eggshells, tooth paste, washing-up liquid
- or salt
- Water
- Mixture of table salt and vinegar
Let’s get started
1. Solid cleaning agents for shiny coins
Choose a cleaning agent that you want to test. For example, take half a teaspoon of powdered eggshells. Place a dirty coin in the center of a damp rag and add the eggshell powder. Fold the rag and rub the coin vigorously between your fingers in the rag for five to ten minutes.
2. Solid cleaning agents
Wash the coin with water. Has it already become cleaner? What other cleaning agents can you use? Next, for example, test toothpaste. Take another dirty coin and rub it together with the toothpaste in the cleaning cloth with your fingers. Wash this coin with water as well. Compare the coins: Which cleaning agent cleaned the coins better?
3. Clean without rubbing?
If it is too strenuous for you to rub the coins clean with solid cleaning agents, you can also use a chemical trick. To do this, you need a glass that you fill to a good third with vinegar. Add salt with a spoon until it covers the bottom of the glass about half a finger high. Stir the vinegar-salt mixture until the salt has dissolved. Then you can gently drop three to four coins into the mixture. Wait five minutes and then take the coins out again. Did it work?
