The correct proportions are 2/3 99% alcohol & 1/3 everything else. The rubbing alcohol you can find in drugstores, etc., typically is only 70%. The initial recipe would have less than 50% alcohol.

Your final mixture MUST be at least 60% (alcohol) to be effective. Make sure your quantities will give you that measure.

To be sure, use 99% rubbing alcohol (isopropyl alcohol) or ethanol.
