For a container just "re-purpose" a used water or soda bottle. How much alcohol do you think you will need for the meals and "uh-oh's" on your hike?
Test cook a couple of meals at home to help you gauge your fuel requirements. Then re-purposed a bottle just large enough to carry the fuel you will need. :-D
Soap and scrubber? An SOS/Brillo pad in a baggie or use your bandana and some Campsuds or Bronner's. Gotta wash that bandana sometimes. ;-)
YMMV
