Even on longer adventures a small bit of multipurpose liquid soap in a re-closeable plastic bag goes a long way. My hands-down, all-time favorite is Dr. Bronner’s Pure-Castile soap, in their 2 oz. bottle. Two ounces doesn’t sound like much, but during a recent three week thru-hike, I still had a tiny bit left over when I returned home. Dr. Bronner’s advertises on their bottle all kinds of uses for their soap. I use it to sanitize hands and showering of course and it’s great for washing clothes, but I draw the line at using it as my toothpaste, which they advise.
Also, Dr. Bronner’s Pure-Castile soap comes in a wide variety of scents, from peppermint to hemp and lavender, or un-scented. Something for everyone.
Even reading the bottle is entertaining.
