I second the jetboil and several wash cloths packed in a small steel bucket. The best reason for this is washing up in camp. Soaking your hands and feet, washing them with Dr. Braunner's, and then treating all of the little cuts and cracks with antibiotic ointment and fresh bandages will make a huge difference and prevent staph, which is getting more and more common down there. Bring an easily accessible personal first aid kit with LOTS of band-aids and tape. Not a "hope I don't need it" kit, but a "gonna use it daily" kit for this reason. If you don't have a small camp stove you can heat up the water on the fire - but doing this clean-up on your own time frame is very nice.
