Removed "up to 30%" for the proportion of water - a comment pointed out it can be higher.
  • Hand sanitiser is widely available, especially in recent months, and reportedly burns well enough to boil water while leaving little residue. The downsides are that it is usually sold as a gel, which is unlikely to flow properly into a double-walled stove, and contains up to 30% water which reduces the heat available.
  • As an alternative, I sometimes use a collapsible wood-gas stove for twigs and leaves when other fuels are hard to get hold of, and some of those stoves are big enough to fit a Trangia-like burner inside. I don't know how the total size and weight would compare to an MSR but that setup would allow you to switch between meths and solid fuel.
