Simply saturate paper towel with lemon juice and place it over the stain. This helps it to cling, and keeps it wet longer. Let it dry, check the stain, and rewet again if necessary until the stain dissolves or loosens sufficiently to easily remove it. Although it requires time, it is easy and effective.
