This video shows us how to clean coins using 3 simple products.
Pour lemon juice, vinegar, and iodized salt into a small container.
There should be an equal amount of lemon juice and vinegar, and use approximately half as much as the lemon juice and vinegar for the salt in volume.
So it would be 1/4 cup lemon juice, 1/4 cup vinegar, 1/8 cup salt.
Stir the mixture until the salt dissolves.
Place the coins into the container, and stir with a utensil for awhile.
Take the coins out afterward, and rinse under cold water.
The coins will then be sparkling clean again.
