Sanitising food prep areas and hands.
Antiseptic for first aid treatment.
A bit on some tissue or paper towel to wipe feet before clean socks or getting into sleeping bag. Very effective against foot skank and drying out waterlogged skin!

Fire lighter.
Stove fuel.
If only there were no toxic additives, medicinal ingestion.

Has any body else had a stove building addiction? I never knew empty cans could be so entertaining. My partner thinks, or has had suspicions confirmed, that i am totally bonkers!!!
