Bacardi makes a denatured alcohol solution -- denatured with water, 25%.
Or, failing that, any of a host of flavors of pure grain alcohol, 95%
ethanol, 5% water (some have called it tincture of water, to keep it from
prying palates) would be effective for this use.  For a comprehensive list
of local vendors, look in your yellow pages under Liquor, Retail.

Your mileage will vary by county ordinances, esp. in bible-belt states.
