Eat out of a plastic container, not your pot. Dehydrated stuff rehydrates in bags or plastic bowls/containers fine. Boil water and pour, you have a clean pot 100% of the time.

I have taken a Brawny towel to wipe out pot/pan - these are rinsable, away from the water source!, and dry fast in the sun. When it becomes too stained and tattered it makes good tinder when we finally drop below 10,000 feet and build a fire.

Use TP and pack out in a ziploc bag adequate to the task. A friend will take a lighter and burn the used TP in her cathole. Better than leaving it for creatures to dig up and decorate the wilderness with, I suppose.
