Denatured alcohol from Lowes, or Home Depot works as well, and it's *dryer*. Rubbing alcohol usually has about 30% water. There are only traces of water in the denatured alcohol. This is mostly ethanol, the same stuff that is in beer, wine, and whiskey. they add about 10% methanol to *poison* it. Otherwise the stuff can get expensive due to the liquor tax. DON'T DRINK THE STUFF.
