The best option for met stoves is medical alcohol, bought in pharmacy or in supermarkets, there are two kinds, one is 96% ethanol plus a bittering ingredient usually bitrex, that's the kind you want, the other kind is Iso mixed with water. I don't recommend methanol, as the quality is highly irregular .
