How to Stay Clean When Hiking: A Small Kit and Simple Habits for Your First Nights Out

Judging by most packing lists, staying clean overnight means carrying half your bathroom. Skip it, and you picture day two: sticky skin, damp socks and greasy hair as you crawl into your sleeping bag next to a friend.

Then there’s the bigger worry: that going without will make you sick. That isn’t fussiness. Plenty of beginners put off a first overnight over it, especially anyone used to a daily shower.

Most hygiene lists are written for long trips and thru-hikers, which is why they look like too much for two nights. What you want is how to stay clean when hiking for a night or two, without carrying your whole bathroom and without getting sick.

You’ll get a small kit and a short evening routine, each habit with the reason it’s worth the effort, so you eat with clean hands, sleep clean, and leave the water and the wildlife alone.

Is It Worth Bothering for Just One or Two Nights?

Yes, a few habits are worth it. In a study of Appalachian Trail backpackers, those who washed their hands after going to the toilet and routinely cleaned their cookware were about half as likely to get diarrhea.

Dry feet and fresh socks help keep athlete’s foot away, and a quick wash helps you sleep well.

It’s easy to think the stakes are low on a short trip. You’re picturing day two, a bit sticky and self-conscious next to a friend in the tent, and that seems like the whole problem. The same small habits that keep you comfortable also help keep you well.

The study of Appalachian Trail backpackers followed 280 hikers, each out for at least a week. More than half had diarrhea at some point, and those who washed their hands after going to the toilet and routinely cleaned their cookware were about half as likely to get it.

It has real limits. These were long-distance hikers reporting on themselves, and the study shows a link rather than proving cause. I still think it matters for a short trip, because the habits are small, so the case for doing them doesn’t need to be large.

A second paper on the same hikers lists their most common complaints: foot blisters (64 percent), diarrhea (56 percent) and skin irritation (51 percent). Feet, stomach and skin are exactly where the habits below are aimed.

Feet are worth a closer look. The American Academy of Dermatology notes that the fungus behind athlete’s foot thrives in warm, moist places like sweaty shoes, which is a fair description of a hiking boot by evening. Dry feet and fresh socks take away the damp it likes.

Then there’s sleep. A quick wash and a clean set of clothes let you lie down in your bag feeling settled instead of sticky, and that makes a first night out much easier.

Every habit and item below has to pass the same test. It earns its place if it helps keep you from getting sick, lets you sleep comfortably, or protects the water and wildlife, and it has to be worth its weight in the pack.

Anything that does more than one job wins, which is why your cook pot keeps turning up in this guide. If you’re skimming, the five things to do each evening are gathered at the end.

What Goes in a Small Hygiene Kit (and What Can Stay Home)

The kit is small: sanitizer with at least 60 percent alcohol, a little biodegradable soap, a few unscented wipes with a bag to carry them out, a small cloth, a toothbrush and toothpaste, fresh socks and a dry set of sleep clothes. Your cook pot doubles as the wash basin.

Those packing lists with half a bathroom in them are built for weeks on the trail. For a night or two, you’re aiming for one small bag, with every item earning its place against the test above.

• Hand sanitizer with at least 60 percent alcohol, so you can clean your hands before food without making any wastewater to deal with.
• A small bottle of biodegradable soap, because a few drops are enough for a wash or a greasy pot, and less soap means less to keep away from the water.
• A few unscented wipes and a zip bag, for a quick wipe-down when you don’t want to walk for water. The used ones ride home in the bag.
• A small cloth or bandana, which turns a potful of water into a proper wash and weighs next to nothing.
• A toothbrush and a small amount of toothpaste, since a night or two needs very little, and a small tube is less to store with your food.
• A fresh pair of socks for each day. That’s my call on the count, because the American Academy of Dermatology’s advice is to change socks every day, and more often when they get wet.
• A dry set of sleep clothes you wear only in the tent, so the day’s sweat stays out of your sleeping bag.
• The cook pot you already carry, which doubles as your wash basin and rinse jug, so it adds no weight at all.

I’d leave behind full-size bottles, a shower bag’s worth of extras and anything that only does one job. Every item adds weight, so the kit stays small and does double duty where it can. The pot is the clearest example: it cooks dinner, then becomes your basin.

Toilet paper, a trowel, period products and hand care after the toilet have their own kit, covered in my guide to going to the bathroom in the woods. The Appalachian Trail study’s clearest result was soap and water after the toilet, so that habit matters as much as anything here.

The rest of what goes in your pack is in my list of hiking essentials for beginners.

Why Hand Sanitizer Alone Won’t Clean Grimy Camp Hands

Sanitizer helps, but it can’t clean on its own. The CDC says it doesn’t work well on visibly dirty or greasy hands, and names camping as an example. Wash grimy hands with soap and water from your pot, and save sanitizer for hands that look clean.

Picture your hands after the first evening at camp. You’ve staked out the tent, handled the stove and fuel, and rubbed in sunscreen hours ago, and now you’re reaching into the snack bag. A squirt of sanitizer feels like the job is done.

Plenty of beginners pack sanitizer and assume hand washing is covered. It’s an easy belief to pick up, since sanitizer is quick and needs no water.

The CDC’s hand sanitizer guidance puts soap and water first, with sanitizer of at least 60 percent alcohol for when soap and water aren’t available. It also says sanitizer may not work as well on visibly dirty or greasy hands, and names camping as one of those times.

The reason is that sanitizer can kill germs on your skin, but it doesn’t lift dirt or grease off it. The CDC also notes that soap and water work better against some germs, norovirus among them.

So match the step to your hands: soap and a little water from your pot when they’re greasy or dirty, sanitizer when they look clean. Rub it in for about 20 seconds, until your hands are dry, and don’t wipe it off before then.

Keep the Pot as Clean as Your Hands

If last night’s dinner is still stuck to the pot, it’s worth a few minutes to clean it before you cook again. The same Appalachian Trail study linked routinely washing utensils with warm, soapy water to less diarrhea.

The method is short, following Leave No Trace and park guidance. Use hot water and a good scrub first, and a little unscented biodegradable soap only if you need it, all at least 200 feet from water.

Strain the dishwater through a fine mesh strainer and scatter it widely, well away from camp, which matters most where bears are around. Then pack out whatever the strainer caught.

How to Wash Up Without Washing in the Lake

Carry water in your pot at least 200 feet, about 70 to 80 adult steps, from any lake or stream. Wash with a little biodegradable soap, rinse with water from the pot and scatter it. Even biodegradable soap affects water quality, so it never goes into the water.

By the second evening your face feels greasy, your hair is flat, and you’d rather not smell in a shared tent. The lake right there looks like the obvious place to fix all of that.

Here’s the method from Leave No Trace’s guidance on waste. Fill your pot at the water’s edge and carry it at least 200 feet away before any soap comes out.

Wash with a damp cloth and a few drops of biodegradable soap. Rinse with water from the pot, then scatter the rinse water over the ground so the soil can filter it.

That 200-foot distance is one of the Leave No Trace basics, and the soap is the reason for it.

When water is short, start with your face, armpits, the back of your neck and your feet. Those are the spots that feel grimiest by evening, and a little water goes a long way on them.

Wipes or a Water Wash?

Both work, and the real difference is what you’re left carrying. Wipes are quick and need no walk, but every one becomes trash you pack out. A water wash takes the pot and a short walk, and leaves nothing behind.

Here’s how the two compare for a quick evening wash.

Whichever you use, wipes stay unscented, and every one comes home with you, including the ones sold as biodegradable.

Can’t I Just Jump in the Lake?

Sometimes, and it can be a lovely way to cool off. Leave No Trace suggests thinking twice where fresh water is scarce, because lotion, sunscreen, insect repellent and body oils all end up in it.

If swimming is allowed and the water isn’t small or scarce, rinse off sunscreen and repellent away from the water first, and never take soap in. Check the local rules before you go in.

I’d treat a swim as a bonus and keep the pot as the washing plan. The 200-foot wash works everywhere, including the places where swimming isn’t allowed.

Why Your Toothpaste Spends the Night With Your Food

Where bears are around, park rules treat your toiletries like food. Soap, toothpaste, deodorant, sunscreen, lip balm and even hand sanitizer go wherever your food goes for the night, never into the tent. The reason is smell: to a bear, toothpaste and lip balm smell a lot like food.

At the end of a long day, it’s natural to tuck the toothpaste and lip balm into the tent pocket, where they’re handy in the morning. Where bears live, that’s the one habit to change.

Shenandoah National Park’s food storage rules list sunscreen, soap, insect repellent, lip balm, toothpaste, deodorant, medications and feminine products as items to store with food, and say never to bring food or toiletries into the tent. Olympic National Park adds hand sanitizer to its list.

So wherever your food sleeps, the kit sleeps too, whether that’s a bear canister (a hard, lockable food container bears can’t open) or a food locker.

Unscented products aren’t an exception. The park lists don’t make one, so the whole kit goes in with the food, scented or not.

Rules differ from park to park, and some require a bear canister. Check the food storage rules for wherever you’re going before the trip.

How to Stay Clean When Hiking Each Evening: Five Steps Before Bed

Each evening, in this order: wash up away from water, dry your feet and put on fresh socks, change into clean sleep clothes, brush your teeth away from camp and water, then put the whole kit in with your food. It takes a few minutes.

The light is going, dinner’s done, and you’re not sure what comes next or in what order. Here’s the order that works, each step with its reason.

1. Wash Up Away From Water

Use the pot-and-cloth wash from earlier, or a couple of unscented wipes if you’re short on time or water.

Body oil works its way into a sleeping bag over time, and a quick wash before bed is the easiest way to keep the inside of your sleeping bag clean.

2. Dry Your Feet and Change Your Socks

Take your shoes and socks off once you’re done walking for the day. The American Academy of Dermatology’s advice is to wash your feet with soap, dry them completely, and put on clean socks that dry quickly or wick moisture.

The reason is the warm, damp spot from earlier: sweaty socks and shoes are where the athlete’s foot fungus thrives. The academy also suggests changing socks every day, and more often when they get wet.

Skip cotton for socks and sleep clothes, because it holds moisture against your skin. My layering guide explains which fabrics dry fastest without the jargon.

Blisters are a topic of their own and worth sorting out before you go. This step is about clean, dry feet for the night.

3. Change Into Clean Sleep Clothes

After the wash, put on a dry set of clothes you keep only for sleeping and never wear on the trail. You’ll sleep more comfortably, and less of the day’s sweat and sunscreen ends up in your bag.

If you’re wondering about a sleeping bag liner, my guide to choosing a sleeping bag covers it, along with the pad that keeps you warm.

4. Brush Your Teeth Away From Camp and Water

Brush with water you’ve already filtered, boiled or treated, never straight from the stream, and do it at least 200 feet (60 m) from any water. That’s the backcountry advice from Alberta Health Services.

As for where to spit, guidance from North Cascades National Park says to spread toothpaste on bare ground well away from camp and water. Spit, spread it out rather than leaving a blob, and put the toothpaste back in the kit.

5. Put the Whole Kit With Your Food

Last thing before the tent, the whole kit goes into the canister or locker with your food, for the reasons above. Check the tent pockets for a stray lip balm before you zip up.

Before the trip, look up the food storage rules for wherever you’re going, and pack the kit in one small bag that can go straight in with your food.
