We prewipe all of the food stuff off of all the dishes with a paper towel and throw that in the fire. If the dog is along, we just let him pre-rinse all of the dishes. Dawn in the first tub and dilute bleach water in the second and air or towel dry. Works great. We use paper when we are in a big hurry, but it is too much waste for us on the longer trips of 14+ days.
