Hillbilly, I use the drug store type peroxide. It works fine. I mix 16oz peroxide, 16oz distilled water, 1/2 cup baking soda, and 1 oz of the green sent-free shampoo/soap. Stirr it up in a large container until everything's dissolved, and divvy it up in a couple of new spray bottles (I get those at the Dollar Store). Don't screw the lids on tight, for at least a few days, because there's a chemical reaction going on there, and those gasses have to vent. Don't shake em up, because it's the equivolent of shaking up a high-powered soda. It'll spew out all over the place. Once the gasses have fully escaped, it's ok to shake it up, but I'd wait at least 5 days or so. Try to keep it out of the sun, as peroxide deteriorates in sunlight--thus their dark bottles.
