Ordinary alcohol distilled from water is only 95% alcohol (ethanol) and 5% water (190 proof). It is physically impossible to get 100% ethanol. Denatured alcohol is simply ethanol distilled from another solvent. It is possible to get 99% (198 proof) alcohol this way. Because we're mixing the alcohol with water, it is silly to get the denatured stuff and then mix with water. Just use the 95% alcohol which is cheaper. Larry Beach, RPT Vancouver, BC Canada
