Heres my recipe, real simple

using an empty clean 1 galon milk jug, fill 1/2 the jug with distilled water, add 1 cup of peroxide, and 1 cup of baking soda, stir the jug, fill the rest of the jug, stir again, place cap on losely and place in a cool dark place. stir the bottle every 24 hours or so, baking soda will settle to the bottom.

also for cover scent, gather 50-100 acrons, crush acorns with hammer, place crushed acrones in pot, make sure its one you wont use again, add water, bring acorns to a boil. let cool, scoop out acrons and throw them away. take the mix and pour into one or more spray bottles. Make sure the cover scent is cool to the touch so you dont melt the bottle. The solution may be a dark color and may stain your clothes, I use the solution on my boots only. works great and smells great.
