When working with food coloring, you can avoid staining your skin by wearing long gloves and a long-sleeved shirt. Sometimes stains are inevitable, however, since blending the ingredients can cause them to spatter and spray the coloring outside the mixing bowl. If food coloring comes in contact with your skin, immediately work on removing it. The less time it sits on your skin, the lighter the stain will be.
Rinse the excess food coloring off with warm water. Dry the area with a paper towel.
Put three tablespoons of salt into a small bowl. Add five tablespoons of either vinegar or lemon juice to the salt. Mash the ingredients together with the tablespoon until they form a paste.
Rub the salt paste into the stain. Massage the salt thoroughly so the abrasive action will lift off the pigment. Rinse the stain again. Keep rubbing more of the paste into the stain and rinsing it off until the coloring is gone.
Wash the area with hand soap, rinse it off and dry it with a paper towel.
