Yeah echoing the 1 quart of 3% hydrogen peroxide, ¼ cup baking soda, and 1 teaspoon dish-washing liquid solution. It may take repeated treatments but definitely works. You mix the ingredients in a bowl, put a dishrag in it and apply the stuff generously to all sprayed skin and hair, let it soak in for about 5 minutes for the chemicals to work, rinse off with really warm water so you can open your pores and let more spray sweat out, and repeat. Been doing that procedure for years and it's worked each time I've been sprayed as long as I'm really vigilant about it.
Tomato juice will almost certainly fail you. It's been shown in lab tests (including Mythbusters) to do next to nothing and people only thought it worked because of olfactory fatigue making them smell tomatoes over the skunk odor.
