Here is a Skunk Tonic recipe from Missouri Conservationist July 2008 magazine. Hope it helps!
Skunk Tonic
For use on people, clothing and pets.
Mix Together:
1 quart of hydrogen peroxide
1/4 cup baking soda
1 teaspoon liquid laundry soap or dishwashing detergent
The first two ingredients form an alkaline peroxide that chemically changes the skunk essence into sulfonic acid, an odorless chemical. The soap breaks down the oily skunk essence and makes it more susceptible to the other chemicals.
Chemicals in this formula are harmless, but try this solution at your own risk. To be safe, keep the formula away from the eyes, nose and mouth of people and pets.
Do not store this mixture or put it in a closed container. When kept in a warm place, the mixture may expand and burst the container.
