>>2674762Clothes: I just pick quick drying, low smell stuff. Especially in warmer weather I take the opportunity to rinse stuff out and dry it on the outside of my pack. In winter I just keep it dry, often with either boiling water in a nalagene or my body heat in the sleeping bag. Permethrin on all of my clothes and shelter at least once a season. I usually have one set of things to wear awake, another for sleeping, plus the stuff like insulation and rain layers, it's just kind of a given that they will be a little icky after a long trip. Exception is socks, I typically have 2 sets of socks and 2 sets of liners and will rotate them daily, plus separate socks to sleep in in cool weather.
Cooking I keep it simple. I don't typically cook directly on the heat to avoid baking food onto things which leaves residue and potential for bacteria or mold growth . I like to just reheat stuff with boiling water in a bowl bag or tupperware with a coozie. The plastic wipes clean easily. I bring a piece of natural scrubby sponge to keep it clean and then I rinse the bowl with hot water. I do bring campsuds if it has been a couple days or if the meal was a little oily. Boiling water sanitizes the cup and spoon.
Self I rarely worry about hair or shaving. I do bring some stuff for things like bike touring where I have the opportunity to swing by a state park with showers. I always have a comb or heavy brush for hair and beard though. I keep hand sanitizer in both my cooking and shit kits, as well as a pocket bidet. I bring a little microfiber camp towel so I can rinse myself off with a little water. To me the most important is oral hygiene so always a toothbrush, paste, and floss. I'll not shower for 2 weeks, but I will brush twice a day every day.
First aid kit is probably on the overprepared side, but I make a specific effort to deal with little things before they become big things especially on long trips. Antiseptics, wound coverings, etc.
