I'm not sure any of that stuff works either but I still use a mix of baking soda,peroxide and green soap in well or distilled water:

1/2 box of baking soda
16oz of peroxide
2oz of green soap
1 gal of water

I have read in different places where people used a "woods tea" made of plants and tree species of the area boiled down into a tea.

Personally I think it would be a whole lot easier to stink like something than not to stink at all.
