   I don't know if it's true but I've been told that different companys use
different things to "denature" alcohol. I was told that they can use any
additive that makes the alcohol undrinkable and that one common addative is
kerosene. FWIW I usw A LOT of denatured alcohol for cleanning electronics
and the brand that I use does not seem to leave a resisdue. I've had no
problems using it. I can find the original can and get the brand name if
you like.
