Let's use volume to find the percentage of alcohol that would result from mixing your recipe:
Your 190 Proof "Everclear" is 95% alcohol. That means that 18 ounces of Everclear is 17.1 ounces of pure 100% ethanol alcohol.
The total volume of your recipe is 32 ounces.
17.1 ounces of alcohol in a 32 ounce volume is roughly 53.43% alcohol by volume.
You want to have a solution that is at least 60% by volume so you must cut the total volume without reducing the alcohol. The hydrogen peroxide and the distilled vinegar both contain water so removing some water would reduce the volume without reducing the alcohol.
Removing the 4 ounces of water will make a 28 oz disinfectant solution of a little over 61% alcohol by volume given the composition of your ingredients.
VERY Important: The solution contains enough acid that when mixed with another common household material (bleach) will release toxic gas (chlorine) to hurt or even kill you.
Do NOT mix chemicals contrary to the indications in the safety warnings on labels.
READ ALL LABELS CAREFULLY.
