Venturing outside can be a messy endeavor.

Bringing soap into the backcountry, particularly for multi-day backpacking trips, is a great way to keep yourself refreshed, sleeping well, and ultimately feeling like a human within wild environments.

That being said, it is important to understand the environmental impacts that using soap outdoors will entail. Choosing the right camp soap is an important part of that understanding, as is developing proper backcountry hygiene practices. Doing your part to <a href=””>leave no trace</a> and minimize impact will increase the likelihood that beautiful places will remain for many generations to enjoy.

Keep reading to discover, exactly, what makes a soap biodegradable, why you should be using one, both outside and at home, as well as specific instructions for disposing of it properly while hiking or backpacking.


  • Use biodegradable soap for all camping/hiking/backpacking needs
  • Dispose of it properly, away from lakes, rivers, and streams
  • Familiarize yourself with alternate cleaning techniques which can limit your soap use
  • Always use soap in group camping situations


  • Use soap, even biodegradable, anywhere near a freshwater source
  • Bring traditional soaps into the backcountry
  • Use more than what is needed

What is Biodegradable Soap?

A biodegradable soap for camping is, simply, one that can be broken down or decomposed by bacteria or other living organisms. Contrary to many popular hand or dish soaps found in homes and businesses throughout the country, camping soaps are efficiently decomposed (eliminated or reduced to negligible amounts) by organic soil.

Biodegradable soap compared to traditional soaps

Traditional soaps, like those, probably, sitting at your kitchen sink right now or found within public restrooms, often contain synthetic (man-made) chemicals. Many of these harmful chemical preservatives, such as parabens, phthalates, petrochemicals, along with artificial colors and scents, do not break down quickly.

This means that if they are disposed of in nature, traces of their chemical makeup can still exist many years later. The negative impact potential on local flora and fauna is considerable, and that is why traditional soaps should never be used while camping.  

Most biodegradable soaps, however, are produced with natural, organic ingredients that break down efficiently when exposed to the bacteria found in soiled environments. These concentrated solutions can, also, provide suitable cleaning power with drastically less soap.

Why You Should Use Biodegradable Soap

Before looking closer at the benefits of using a biodegradable soap over a traditional version, we should address the reality than any soap used outdoors will cause an impact. The highest quality, all-natural, organic, biodegradable soap still has the ability to affect the environment in a negative way, especially for aquatic species.

If you are, truly, adamant about leaving no impact, you will, likely, learn to hike and camp without the use of soap. This is not to say that using a biodegradable soap is considered unethical or unacceptable. We’re just acknowledging the fact that any soap, even biodegradable, will cause more impact than none at all.

Most, ourselves included, will still justify bringing soap into the backcountry for the sake of general hygiene, health, and to aid in the prevention of communicable diseases commonly transferred through camp cookware. Following strict guidelines for its use and disposal helps us remain responsible and aligned with LNT principles.

While minimizing environmental impacts and adhering to LNT practices are the most obvious reasons for why you should be using a biodegradable soap when cleaning up outside, there are numerous other benefits that you may not be aware of yet.

Benefits of using biodegradable soap

Fewer environmental impacts

The very nature of a biodegradable substance means that it will become, virtually, undetectable over time (when disposed of properly). Unlike other harmful chemicals or plastics, biodegradable soaps pose very little threat to existing ground vegetation or surrounding plant life.

Additionally, they pose less risk to aquatic species. Although soap exposure to waterways should be avoided at all costs, it’s nice to have a little extra assurance in the event that we fail with this responsibility.

Extended use out of a single bottle

Biodegradable soaps are concentrated and designed to be mixed with water. This means that you can, typically, use only 1-2 drops of soap per cleaning application. One small bottle of biodegradable soap can, actually, last longer than a larger version of the traditional variety.

Healthier ingredients

If you already pay close attention to the ingredients that make up what you eat and drink, why not extend this monitoring to the soaps and lotions that you place on your skin? Chemical laden soaps can contain known carcinogens and skin irritants

I don’t know about you but natural ingredients that I can pronounce, like olive oil, coconut oil, or jojoba oil, commonly found in hiking soaps, give me extra confidence to know that I am not risking my health with a product.

How to clean if you decide not to use soap

If you make the decision to go soapless when handling your hygiene needs in the backcountry, consider some of the following strategies:

  • Go for a swim! As long as you’re not heavily covered with bug sprays or sunscreens, taking a dip in a fresh body of water is one of the best ways to stay refreshed and clean sans soap.
  • Sand, dirt, or pine needles can provide the abrasive qualities, often desired of soap, to aid in cleaning dishes. Simply rinse with fresh water when you have removed the heavy soot or food debris.
  • Protect yourself from sun exposure and bugs with clothing and/or netting, as opposed to lotions and sprays. Permethrin-treated or UV-protected clothing helps limit the amount of bug spray or sunscreen you need to clean from your skin each night, further reducing your need for soap on the trail.

How to Dispose of Biodegradable Soap Responsibly

There is a common misconception among many hikers, backpackers, and campers that biodegradable soap doesn’t pollute the environment. As a result, these folks pay little attention to how much they are using, where they are using it, or how they, ultimately, dispose of it.

Using a biodegradable soap near or within any water source is a serious violation of LNT practices. It carries numerous environmental and marine wildlife impacts that cannot be reversed. Please, do not shower, wash your face, or do your dishes with soap in any river, lake, or stream.

Here’s what to do instead:

  1. Carry the necessary water for your cleaning tasks, via a bottle, hydration reservoir, or collapsible bucket, to a site that is at least 200 ft. away from all sources of freshwater.
  2. Use soap sparingly – 1 to 4 drops is more than sufficient in most cases. Biodegradable soaps are highly concentrated so that you can limit what you need to use outside. Follow the instructions for mixing with water, which are typically found on the bottle.
  3. For best practice in disposing of outdoor soap, consider digging a cathole into which you can pour your ‘grey water’. This surrounds the soap with the organic soil compounds that aid in efficient decomposition. It, also, helps to prevent potential surface runoff during rain events.
  4. It is, alternatively, acceptable to disperse small amounts of grey water in a wide arc (imagine slinging the water out of your pot, as opposed to pouring it). This method prevents the concentrated pouring of the entire solution in one spot and saves you from having to dig a cathole.
