I am TERRIBLE at math and I bought a big ol' bottle of virosan... now here is my dillema-
I have a bottle I can fill with 22oz and it is not all the way full (that's just where the oz measurements stop) so i figure I'll use it as a virosan spray bottle but the ratio is this -
"to prepare 1 gallon of a .5% solution (which I'm assuming is what I would need since this is the percentage they use to disinfect teats before milking) for dipping teats, mix 32 fluid ounces (1qt) of Virosan solution with 96 fluid ounces (3qt) of clean water." So...

32oz/96oz = 1 gallon ... all I want is 22 oz.
x/x = .172 gallons (22oz?)?

PS: there are 128 fl. oz. in a gallon.
