Things You'll Need
Instructions
Pour 2 cups of warm water into a bowl. Mix with 2 teaspoons of dish soap.
Wet a clean cloth with the soapy water. Gently rub the dirty note in a circular motion.
Another option is to clean the paper money in a washing machine. Place the bills in your pants pocket and run the pants (and your money) through a wash cycle, using detergent as with a regular load of laundry.
For especially hard-to-remove markings, put 2 teaspoons of rubbing alcohol on a clean cloth. Gently rub the bills until the dirt is removed, then rub clean water on the money to remove the alcohol.
Whichever method you use, allow the bills to air dry. This can be done by placing the money in between paper sheets and pressing them in a book.
