Scent Killer - 7.57 litre recipe

3.758 litres (1 gallon) of Hydrogen Peroxide (3%)

3.758 litres (1 gallon) of distilled water. (DO NOT USE TAP WATER!)
473.184 ml (2 cups) of baking soda.
236.592 ml (8 oz) (2 cap fulls) of Sport Wash or unscented soap.

Mix in a large bowl (don't shake up in milk jug) so the baking soda dissolves) and pour into jug.
Let sit open for several days, so the chemical reaction settles down, and don't leave in a tightly sealed container! I use 2 4 litre milk jugs with a screw on cap. I have several used sprayers and fill them from one of the two jugs.

Here's a smaller version of the recipe above if you only want to make a little to try it out:

Mix in a large bowl (don't shake up in milk jug) so the baking soda dissolves) and pour into jug.

I have several used sprayers and fill them from the jug.

Make your own cover scent
Gather up leaves sticks dirt and pine needles from your hunting area, take it home and put the mixture in a pot with distilled water. Bring it to a boil and let it stand for a few hours, then pour the water into a empty spray bottle.
