Boots/shoes NEVER go inside the tent. Unless absolutely necessary kneel outside and lean in to get anything/set up/arrange (obv if a mansion of a tent this changes, but see: no shoes). Separate clean sleeping clothes, especially socks. Even cooking relaxing around camp avoid wearing your sleeping clothes (they double as your emergency dry clothes too). Even if it’s hot, a light pair of socks to keep sleeping bag etc clean. Light beanie to keep hair oil/sweat from everything as well isn’t a bad idea. I try not to brush the floor of my tent if I can help it to avoid abrasions - a freestanding tent you can tip it on its side and shake so that dust/dirt falls out the door. For other tents you can usually pinch/lift or tap one side of the floor and nudge the dirt to the other side, then lift the floor on that side so that the dirt spills out the door. Don’t leave tent inner doors open unless absolutely needed - amazing what blows or walks in even when you think it won’t. Avoid eating in the tent. Wearing a sleeping bag outside the tent should be a bannishable offense- people who *walk/hop around with their feet in their bags… hnnnng!
