You'd never know to look at me but I am a clean freak. Not so much a germaphobe, just a lazy slob who dislikes dirt. Or at least dirt in the wrong places. Having said this, I can often be found adorned with knotted locks, unmanicured fingernails and rumpled clothes. But I have the hygiene thing covered, even on canoe trips.
As for bodily hygiene, a near daily dose of full immersion swims does the deed. If in cold water conditions then a quickie splash and scrub will have to do. Standing next to a pot of hot water isn't the same experience at all, but it sure is nice to cleanse the body and reward the soul. Does wonders for the spirits, off with the old you and on with the new. I and my partner will suffer no more than 2 days between some sort of bathing ritual. It's weird, but I love getting in to the toil and the soil, the grit and the grime, I just don't like wearing it for too long; and I hate going to bed smelling of bug spray, smoke, sweat and whatever rank odours are following me. I've been known to go jump in the lake just before bedtime. A cold shiver swim under the stars is an amazing experience. A cleansing one in so many ways.
As for attire, I will pack 1 change of outer clothes. That means 1 extra pair of pants or shorts, and 1 extra long sleeve shirt. As soon as the first set of clothes get too smokey/dirty I'll bathe and change into the 2nd set of clothes. If our trip outlasts these then it's time for a fully clothed plunge and scrub; laundry and bath all in one pleasurable go. If I overpack anything then I'd rather have "too many" pairs of quick dry underwear and hiking socks. I never try to wash those. I often wear the undies whilst swimming but not too soon enough they'll go into a drybag for the trip home as dirty laundry. Yes, I go through a number of socks and under garments, but it's a small price to pay for the sweet smell of happiness. A completely separate set of poly-merino type underwear and warm socks only for sleeping complete the wardrobe. Compression sacks are great for clothing. There's always room somewhere to tuck in another pair of undies and socks.
Finally, an extra set of outer clothes, shirt, pants and jacket all wait in the vehicle at the take-out. It feels good to bring the memories home; the stank can get stuffed into garbage bags back amongst the gear for the ride home. A parking lot can't be too crowded to stop for our final post-trip metamorphosis.
I've learned all this the hard way, having endured too many trips inadequately clean and clothed.
