Whenever you look into things a little things get dicey.
Ethynol is made from any number of edible produce:
potatoes, corn, beets, fruits, sugar cane, and grain. Edible in moderation for us humans.
Because it is, our governmint, the ATF, tells the makers they must poison the ethyl alcohol. They do this by adding methyl a. (wood alcohol.) 100% poisonous to humans and probably is the additive that makes stove fuel nauseating to some.
Denatured alcohol S-L-X (?) from the hardware is that edible alcohol made poisonous, otherwise it would come in glass and be called vodka and taxed to hell. On the gallon can I use for epoxy cleanup they say it's a "clean burning fuel for marine stoves." There is no MSDS on the can, so casual users like me don't know the composition of the solvent. I use a lot of it and breathe it all the time.
Some agency (the ATF?) governs what can be labeled 'denatured alcohol.' Kleen Strip SLX is reported by one guy to contain 80% methanol, 17% ethanol, 3% MEK. Not something you'ld want to use in an enclosed space, I think, for clean up or fuel. (I have not researched this myself. but I will now get the MSDS for the Kleen Strip I use. I know no one should burn methyl on a boat!)
Who can say what IS a stove fuel?
On the Parks site, they list ingredients as Ethyl a. 93 - 96%, methyl a. 4 - 6%, m. Isobutyl Ketone 1 - 2%, Ethyl Acetate 1 - 2%, Gasoline 1 - 2%.
Parks makes the product for many labels.
Trying to make the point here that maybe this fuel is not a good thing to burn below without direct ventilation. 'Safer' (NONE OF THIS SOUNDS SAFE) fuel might be gotten in the states, but what would you be getting in the Caribbean Mexico or the Pacific?
Any thoughts?
