I use the travel pack Cottonelle flushable wipes to clean up after relieving myself. I use travel pack Cetaphil wipes or baby wipes for sensitive areas, and I use WetOnes type disinfecting wipes for cleaning parts getting rank or blood and such after breaking down an animal.
Alcohol or Benzalkonium chloride type depending what your skin will put up with.
The travel pack sizes seem to be just right for a hunting trip.
