I used distilled water,one gallon
Poured some of the water out to make room for the other stuff
Box of baking soda
bottle of peroxide
2 squirts of the green scent free hair and body soap
Pour everything into the gallon jug
Put the lid on,shake like crazy
Loosen the lid,watch the foam, well, foam out the top.
Tighten lid,shake like crazy
Repeat
repeat
repeat
let sit with lid loose for a couple hoursso it doesn't build up pressure and explode.
Skake some more,man that baking soda is hard to get to dissolve!
Let sit
shake
pour into old scent elimination bottles with the spray tops
Makes one gallon, for about 4.00 or less!
