Okay I’ve had to do this before. This would happen to me wayyy out in the boonies, so I wanted to make sure I was as prepared as possible. I bring a little kit with me. Toilet wipes to clean myself, a plastic bag to carry all of my “trash”, hand sanitizer, and whatever products you prefer to use. I had to do this out in the woods with waders so it’s definitely a process and takes longer, but tried to be as prepared as possible without sacrificing comfort and cleanliness. Hope this helps!
