If I remember right, the formula is: A pint of hydrogen peroxide, a cup of baking soda, and a squirt of dish soap. Rub the mixture on the dog or car seat or whatever. Let it sit for a bit, rinse it off. The smell is gone. I have used this several times on a dog who couldn't be convinced that skunks don't have a sense of humor. It works. Pheasant hunters will mix it up ahead of time just in case.
