How we pack for two weeks in a carry-on: we do laundry. This is the whole kit.
Washing

Lewis N. Clark
SinkSuds Travel Detergent
Liquid detergent made for washing clothes in a hotel sink, in TSA-sized bottles. It rinses out fast, which is the thing that actually matters when you’re wringing a shirt over a basin at 10pm. This is how two weeks of clothes fits in a carry-on.

Arm & Hammer
Power Sheets Laundry Detergent
Detergent as dry sheets, so it doesn’t count as a liquid and can’t leak. One sheet does a machine load at a laundromat or a rental, and half a sheet handles a sink wash. Thirty-five loads weighs less than one bottle of the regular stuff.

Tide
1-Load Travel Packets
Single-load Tide packets for when you find a real washing machine. No measuring, no carrying a bottle, no guessing at whatever the laundromat vending machine sells. A few of these flat packets ride in the bottom of the bag until machine day.
Drying

HONGYUTAI
Retractable Travel Clothesline
A stretchy clothesline that hooks across a shower or a balcony, with no pins needed because the cord grips the clothes itself. Suddenly the whole bathroom is a drying rack. Retracts to pocket size, and it’s the difference between damp clothes and dry ones by morning.

EasyAcc
Slim Rechargeable Travel Fan
Slim enough to stand on a tray table or a nightstand and strong enough to actually move air. This is for hotel rooms with no fan and windows that don’t open, which is more of them than you’d think. Rechargeable, so there are no batteries to hunt for. Pointed at a clothesline, it cuts drying time in half.

Rynapac
10L Waterproof Dry Bag
A roll-top dry bag that keeps water out or, just as usefully, keeps wet things in. Swimsuits, a rained-on jacket, laundry that didn’t dry in time: they ride home without soaking everything else. It packs flat and weighs next to nothing until you need it.
