Steve-
It’s possible to stay relatively clean on a long-distance hike. I cannot stand getting into a nylon sleeping bag swetty & dirty, so i do a number of things to stay clean on a hike.
(1) Sweating: Try to sweat as little as possible: I use various layers to regulate my body temp. according to the conditions, but primarily i try to keep from sweating. This means that even in cold temps I will hike in shorts and t-shirt a lot. When i stop for a break, i put on warmer clothes. In hot temps. i will soak my shirt in a stream/creek and put it back on wet (on a really hot night, this also helps with sleeping on top of a sleeping pad). The reduced sweating not only helps in keeping cleaner, but it also reduces the hypothermia issues in colder weather and by keeping your body cooler, it works more efficiently, so you can walk greater distances with less effort if you need to.
(2) Swimming: I always swim in ponds/lakes/rivers unless its winter-like conditions. This greatly aids in keeping clean. I never use any soap & i always swim downstream of a trail crossing if its a creek/river.
(3) Towel Bath: At the end of the day i heat up water in my cook pot, add a bit of “Dr. Bronners” peppermint soap, and take a full towel bath from head to toe. (i carry a wash-cloth) I then put on my clean sleeping clothes (town clothes) and cook dinner. This takes a bit of time, and some of my trail buddies give me a hard time for doing it (they’re jealous!), but it sure feels great to get into the sleeping bag squeaky clean! It also helps with general hygene, chaffing, and foot issues.
(4) Motels/Hostels: Once in a while, its great to get fully clean and wash your hair, shave, etc.
On my first thru-hike ('96 AT), the Ranger @ Daicey Pond did not beleive that i was a thru-hiker - too clean! He said that i was lying & that i could not stay in the thru-hiker area (back then, it was @ Daicey and it was FREE to thru-hikers)!!! I didn’t know what to do, other than to go get the other thru-hikers to vouch for me, but then the Ranger said, “Don’t bother, they are probably your friends so they will lie as well.” Finally the thought occurred to me to show him my feet (i hike in sandals), so i propped my feet right on top of his desk, and he finally realised that i wasn’t lying & let me stay with the other hikers! (my feet looked like i had been through a war, without combat boots)
