Period underwear takes forever to dry? Why, and how to dry it faster without wrecking it

Step by step

1. 1

   Wring the right way: roll it in a towel

   Lay the pair flat on a dry towel, fold the towel over it, roll the towel up tightly and press or kneel on the roll for half a minute. The towel pulls most of the water out of the core without the twisting that stresses the barrier and elastics. This one step removes more water than anything else you can do.

2. 2

   Hang it gusset-out, in moving air

   Hang the pair open, gusset facing the air, on a rack or hanger where air actually moves - near a fan, an open window, or the airflow of a heating or cooling vent. Still air in a bathroom is the slowest place in the house. Do not fold the gusset closed against itself.

3. 3

   Speed it with a fan, not with heat

   A small fan pointed at the rack cuts drying time dramatically and costs nothing in wear. High heat is the thing to avoid: radiators, heated towel rails and the dryer's hot setting shorten the life of the barrier and elastic. The wash guide's answer is to avoid the dryer; if your pair's care label permits a low or no-heat tumble, keep it to finishing a pair that is already nearly dry.

4. 4

   Own enough pairs that drying time never matters

   The real fix is rotation. With a pair worn, a pair drying and a pair clean, a slow dry is irrelevant. Most people land on six to nine pairs for a full cycle; the how-many-pairs guide does the math from your cycle and how often you can wash.

Why it takes so long

A pair of period underwear is three fabrics stacked: a wicking top, an absorbent core, and a leakproof barrier. The core is designed to take up liquid and hold it, so after a wash it is holding water. The barrier under it does not breathe, so that water can only leave from the top side, through the wicking layer. Regular underwear is one thin layer that dries from both sides. That is the whole difference, and it is why a pair can feel dry on the outside while the core is still damp.

The dryer question

Heat is what ages a pair. It stiffens the barrier film, relaxes the elastic and, over many cycles, shortens the two-year, forty-plus-wash life most brands quote. That is why the standard advice, and the wash guide's answer, is air-dry. The care label on your pair is the final word for that pair; where it permits a low or no-heat tumble, a short tumble to finish a pair that is already nearly dry is a small trade, while a hot cycle from wet is what wears pairs out early. Never dry a pair on a radiator or a heated rail.

A damp pair is not a wearable pair

Wearing a pair before the core is fully dry is the fastest way to odor and to skin irritation, and it also means the pair starts the day already partly loaded. Press the gusset between your fingers before you put it on; if it feels cool, it is still damp. When drying time is tight, the answer is another pair from the rotation, not a damp one.

Travel, dorms and no dryer at all

Away from home the towel roll is everything. Wash the pair in a sink with a little detergent, rinse until the water runs clear, roll it in a hotel or dorm towel and press hard, then hang it open near any moving air. A pair rolled well will usually be dry by the next evening; a pair simply hung wet in a still bathroom may not be dry in two days. Pack one more pair than you think you need for the trip and the drying time stops mattering.
