Which solvent for corrosive ammo?

[Johnny Peppers]

I use a mixture of Windex, hydrogen perioxide and Simple Green. A quart is made up with a sixteen ounce bottle of perioxide, a tablespoon of simple green and the rest windex.

That is almost the mixture we used for wetting the patches when loading our muzzle loaders for competition. 2 ounces hydrogen peroxide, 2 ounces 409, 2 ounces water soluble oil and enough water to make a quart. Mixed it was milky colored and called "Moose Milk". It wasn't good for cleaning the bore, but helped when you had to shoot a long string without cleaning. Hot water was used for clean up.
Remember that whatever you mix, the water is what dissolves the potassium chloride. A little soap acts as a wetting agent, getting the water into the cracks and crevices.
