. . . but the non-residual property is good! It means that any plant
matter coming into contact with a sterilized surface does not get a
chemical poison. How about commercial methylated spirits, which will be
more poisonous than ethanol, but better than putting up with residues.
Maybe you can even get it without the blue dye and taste denaturant.
Good luck Jayakumar. Mike.
