Short answer: away from home you have three options and each has one trick. In a hotel, wash in the sink and dry with the towel-roll method, which cuts drying time roughly in half. At a laundromat, inspect the drum before you load it and never leave the building. On a shared or dorm machine, set a phone timer for five minutes before the cycle ends. And pack pods rather than liquid, because a pre-measured solid travels better than a bottle in every sense.
What to pack
| Item | Why |
|---|---|
| 2 to 4 pods in a sealed bag | Pre-measured, no spill risk, no bottle to leak over a suitcase |
| A flat rubber sink stopper | Hotel basins rarely hold water, and this solves it in two seconds |
| Two or three inflatable or folding hangers | The single most useful thing in a hotel bathroom |
| A mesh bag | Dirty clothes in the case, delicates in a shared machine |
| One dryer sheet | Goes in the suitcase itself, not just the dryer |
| A short length of cord | A washing line between the shower rail and a door handle |
Flying with detergent
Liquid detergent counts as a liquid, so in carry-on it falls under the 100 ml (3.4 oz) container limit and has to fit in the clear bag. Pods are solid and are generally allowed in carry-on without that restriction, which is the practical reason to travel with them.
Two caveats worth taking seriously. Screening is always at the officer's discretion, and powders and gels sometimes get a second look, so keep them in their original packaging or a clearly labelled bag and put them somewhere you can reach. And rules differ by country and change over time: check your airport's current guidance, or the TSA's "What can I bring?" tool if you are flying in the United States, rather than trusting a blog post, including this one.
The hotel sink method
- Fill the basin with lukewarm water and dissolve a pod completely before anything goes in. Never put an undissolved pod against a garment.
- Submerge one or two items. Two shirts is a sink load; four is a wet mess that will not dry.
- Press and squeeze for two minutes. No rubbing, no wringing.
- Drain, refill with clean water, press again. Repeat until the water runs clear, usually twice.
- The towel roll. Lay the garment flat on a dry bath towel, roll the two together tightly like a swiss roll, then press down along the roll or stand on it. This pulls out far more water than hands can.
- Hang on a hanger, shape it with your hands, and leave it over the bath or in front of the air-conditioning unit. Turn the extractor fan on and shut the bathroom door.
- Shirts and underwear dry overnight. Denim and anything thick will not; do not try.
The laundromat, in order
- Go at an off hour. Weekday mornings are empty; Sunday afternoon is not.
- Bring small change and a card. Many machines take both now, but not all, and the change machine is often broken.
- Check the drum before you load. Run your hand around it for dye, grease or a stray red sock. This is the step that saves a whole load.
- Use the right size. Commercial drums are large; one pod is enough for a normal load, two for a packed one or hard water.
- Pod in the empty drum first, then clothes on top, three quarters full. The dispenser drawers in commercial machines are usually filthy.
- Cold, normal cycle for almost everything.
- Do not leave the building. Finished loads get moved, and sometimes they get taken.
- Clean the dryer lint trap before you use it. Commercial dryers run blocked more often than not, and that alone doubles your drying time and your cost.
- Dry on medium, not the hottest setting. Commercial dryers run far hotter than domestic ones and will cook elastane.
- Fold at the machine while everything is warm. It is the only way to come home without creases.
Shared and dorm machines
- Set a timer for five minutes before the end. Almost every conflict in a shared laundry room is about a load left sitting.
- Never unload someone else's wash onto a dirty surface. If you have to move it, use a clean basket and fold the top item so they can see you were careful.
- Do not claim two washers and a dryer at peak time.
- Wipe the detergent drawer and the door seal if you use softener, which you should not be using anyway.
- Wash cold. You do not know what the previous person ran, and cold protects your colours from a drum that is never cleaned, as covered in how to clean a washing machine.
- Bag delicates. Shared machines spin harder than you would at home.
Packing so there is less to wash
- Merino wool is the travel fibre: it resists odour for days and dries fast. Air it overnight rather than washing it, as in how to wash wool, cashmere, silk and linen.
- Dark, matte synthetics hide marks and dry overnight; pale linen looks wonderful and arrives creased.
- Roll rather than fold, and put a dryer sheet in the middle of the case. It keeps the whole suitcase smelling clean and cuts the static that builds up in a packed bag, which is the same mechanism described in how to get rid of static cling.
- Keep one mesh bag for worn clothes so the clean side of the case stays clean.
- Hang the outfit for tomorrow in the bathroom while you shower: fifteen minutes of steam removes most travel creasing, as in how to get wrinkles out of clothes without an iron.
The first hour home
Unpack the case the day you arrive rather than leaving it in the hall. Anything damp, anything worn against skin and anything that went in the mesh bag goes straight into a cold wash with two pods; the case itself gets left open to air. Clothes that sit packed and slightly damp for three days come out smelling of exactly that, and the diagnosis then is the one in why do my clothes still smell after washing.
Frequently asked questions
Can you take laundry detergent on a plane?
Liquid detergent is treated as a liquid, so in carry-on it must be in a container of 100 ml or less inside the clear bag. Pods are solid and are generally allowed in carry-on without that limit, which makes them the practical choice for travel. Screening is at the officer's discretion and rules vary by country, so check your airport's current guidance before you fly.
How do you wash clothes in a hotel sink?
Dissolve a pod fully in lukewarm water, submerge one or two items, press and squeeze for two minutes, then rinse in clean water twice. Lay the garment on a dry bath towel, roll the two together tightly and press down to force out the water, then hang it and run the bathroom extractor fan with the door shut.
How do you dry clothes fast in a hotel room?
Use the towel-roll method to remove most of the water first, then hang the garment on a hanger in the bathroom with the extractor fan running and the door closed, or in front of the air conditioning. Shirts and underwear dry overnight; denim and heavy fabrics will not.
How many pods do you need in a laundromat machine?
One for a normal load and two for a packed commercial drum or if the local water is hard. Put the pod in the empty drum before the clothes rather than using the dispenser drawer, which is rarely clean.
What is the etiquette for a shared laundry room?
Set a timer for five minutes before your cycle ends so you are there to unload, do not occupy more machines than you need at peak times, clean the lint trap after using a dryer, and if you have to move someone's load, use a clean basket rather than a surface.
What clothes are best for travel?
Merino wool, because it resists odour for several days and dries quickly, and dark matte synthetics, which hide marks and dry overnight. Linen looks good and creases immediately, so pack it knowing that.
How do you keep clothes smelling fresh in a suitcase?
Pack a dryer sheet in the middle of the case, keep worn clothes in a separate mesh bag, roll rather than fold, and never pack anything damp. Air the case open for an hour when you arrive and again when you get home.
