The Skunk Remedy Recipe
In a plastic bucket, mix well the following ingredients:
1 quart of 3% Hydrogen Peroxide
1/4 cup of baking soda
1 to 2 teaspoons liquid soap
for very large pets one quart of tepid tap water may be added to enable complete coverage.
Wash pet promptly and thoroughly, work the solution deep into the fur. Let your nose guide you, leave the solution on about 5 minutes or until the odor is gone. Some heavily oiled areas may require a "rinse and repeat" washing.
Skunks usually aim for the face, but try to keep the solution out of the eyes - it stings. If you have any cuts on your hands you might want to wear latex gloves for the same reason.
After treatment, thoroughly rinse your pet with tepid tap water.
