Soap and water
Almost the same exercise you can repeat by using soap instead of vinegar with the difference that it is not necessary for them to soak for hours in the soap. How to clean the old coins with soap?
Step 1 – Again, take a bowl and fill it with distilled warm water. Add a few drops of mild dish soap and stir together. After that put the coins carefully in the bowl and scrub them by either using your hands or a soft toothbrush.
Step 2 – After you gently rubbed the dirt away, rinse the coins with a distilled water.
Step 3 – Let the coins dry and then enjoy the shining new look they have!
Hydrogen Peroxide or Mouthwash.
Now with these two options for cleaning dirty and grimy coins, the procedure is almost the same. You might be surprised to read that but both Hydrogen Peroxide and different types of mouthwash actually work great and remove stains from old coins. Use a small container or a bowl to fill up with either Hydrogen Peroxide or a mouthwash of your choice, and let the coins sit and soak.
What is different with these types of cleaning old coins is the time of period they have to soak. If you put your old coins in a bowl of Hydrogen Peroxide, then let them there for at least 24 hours. And if you’ve chosen to use mouthwash, about 12 hours should be enough.
When you get the coins out of the container again rinse with distilled water and let them dry completely.
These different solutions for old coins and dirty ones are perfect if you want to take care of your money and make them clean again.
