this is an excellent point and one I hadn't borne in mind previously. I guess if you are using such a bottle with meths for a few days and subsequently store it dry it is likely to be OK, but it would be easy to accidentally leave it for longer than this, especially if you were not aware of the hazard.
When carrying fuel bottles it is a risk vs consequence game; it is not that they are likely to leak inside a bag, it is more that if they do (and it only takes a tiny piece grit in a seal to provoke a leak and plastic bottles can split of course ) then the result is a lot of quite needless misery. Of the likely liquid stove fuels none of them (with the possible exception of some burning alcohols) are likely to simply evaporate and leave no stains or smells behind. Clothing is bad enough when contaminated with fuel but the prospect of fuel contaminating foodstuffs hardly bears thinking about.
As above I carry the meths in a SIGG fuel bottle in a cage below the down tube.
I know about the effect of ethanol on rubber and some other polymers but I'm surprised about it (or some other component of meths) attacking "alloy". What's the evidence for this, please?
