Marine alcohol, sold in the paint section of Walmart, home despot, Lowers, etc. works great. It actually says it is for marine stoves as well. (http://theboatgalley.com/using-an-alcohol-stove/ ) .
Additionally, as the story notes, you can also use Heet brand gas line antifreeze. It’s basically just isopropyl alcohol.
If you want rubbing alcohol, go with the one that’s 90-91%. 70% doesn’t heat as well in my experience.
With all three, you have to be really careful not to get the alcohol or the soot in your food. US law requires denaturants, which are typically toxic. Likewise, methanol is also present in some of the available alcohols, which should also be kept out of your food.
Thanks for the info. I’ve got some 70% stored for emergencies that would be a backup to a backup in this case.
I’d use a covered pot based on what you told me.
Denatured alcohol or HEET gas line antifreeze (methyl alcohol) work best.
You can buy the brass alcohol stoves for about $15 and they'll last forever.
Made a woodgas stove from 2 cans. Works great.
