wow, a lot of good ideas....
May change the way I do things....
Here is what I do....
For myself in the shell without sink and running water, I usually use baby wipes to clean most things. If I have a really dirty pot (stew or curry...) I will use some hot water and soap to wash. Of course, scrub and rinse outside the camper. Dry with a quick-dry cloth.
If I am at an organized campsite or if I have tables and such set up, will wash in a folding bucket. Rinse with water. May spray with a water bleach solution and let air dry. Since it rains a lot up hear in WA state, sometimes can't do this.
Keep it simple, don't get a lot dirty you don't need to, and clean as you go. Amazing how simple things can be if I think ahead.....
Every now and again, I wish I had a sink with running water. This is true when my bro is using his and it is raining outside......
But then, hey, where is the fun?
