If "high ethanol content blends like Green denatured produce a little more soot", how does Sunnyside with an even higher percentage? Since "Complete combustion of ethanol forms carbon dioxide and water vapor", I'm thinking Sunnyside may burn cleaner (less soot) since it doesn't have as much other stuff in the mix. Is there an optimum blend to eliminate soot?
Russ,
Excellent questions, but I don't have a definitive answer (yet). I've got anecdotal indications that a mix of ethanol with water without some of the denaturing agents found in denatured alcohol will burn cleaner. However, I'm not quite ready to "publish" that yet until I've been a little bit more thorough.
A mix of around 90/10 ethanol/methanol is supposed to be very clean burning according to people that I've talked to, but I haven't personally verified that yet. I've obviously got some more experimenting to do.
