I used the recipe wirehair posted for the first time this season. It works! Instead of shampoo I used Scent Killer laundry soap and I use regular tap water instead of distilled.

Last season I used diluted baking soda in a spray bottle which works also but I would guess the peroxide helps in bacteria control.

ONE CAUTION. Baking soda is a salt and will tarnish any metal on your boots, your bow and the spring inside the pump mechanism of your spray bottle. I dab a little vegitable oil or apply camo tape on the metal bow parts to prevent rust. I also empty the spray bottle every few days and fill it with plain water. After spraying a few times, I let the water disolve any leftover salt, then I refill the bottle with the scent killer solution. Don't reprime the pump until you are about to hunt.
