Widely available, easy-to-produce, safe and nomad-friendly hygiene products/tool

[Ucy]

As a nomad, it's important to have products/tools that enable you ease yourself when pressed with no toilet around, also get yourself cleaned and not leave even a single or microscopic trace like fecal matter anywhere on your body. This means your hygiene products or method must be very effective yet safe on your body
- Other things to consider: bathing products, mouth wash etc.


What method or products/tools would you use to achieve best hygiene practice, not just for yourself but other people and environments.


Mine are:

Small digging tools for creating small hole (about 1 or 2 feet deep). When I'm done easing myself, I cover the hole with soil. Then use tissue to clean that body part properly, and soap + water for extra cleaning of the already tissue-cleaned part. The cleaning will be done with my left hand ofcourse
And after the cleaning is completed, the left hand is washed with the soap and water, followed by right hand.
Tools/products I will always have in my backpack or carry along with me to get this done effectively:
* Empty inflatable container for collecting water
* Biodegradable Soap
* tissue
* digging tool
* small expandable lightweight shelter for privacy while easing myself.
Etc


For bathing and mouth cleaning:
* the biodegradable Soap
* inflatable bucket
* towels
* the small expandable lightweight shelter for privacy
* Toothbrush, toothpaste, salt, ash, inflatable cup,
Etc


Do you have better method for easing yourself at random places without messing up the environments, or for keeping the lower part of your body very clean without contaminating your hands, water containers and other belongings?
