How to wash Linen - (2026 guide)

The Care Guide

100% linen is the most forgiving fabric you can own, if you treat it right. It's also the easiest one to shrink, stiffen, or fade if you don't. Here's how to wash it properly, from Santoli Napoli, makers of 100% linen shirts in Napoli, Italy.

Linen is a natural fiber. It comes from flax. It's been around for 6,000 years, and it lasts longer than almost any other fabric in your closet, but only if you stop doing three things that will ruin it in a single wash. If you already own linen shirts, these steps will keep them looking good for a decade. If you're about to buy one, this is what you need to know before your first wash.

Care depends on what the shirt is made of, so start there. Santoli Napoli shirts are 100% linen, never a blend, cut and sewn in Napoli by Partenopea Camicie, and the core cloth is Albini woven in Italy at 160 to 190 GSM. A shirt at that weight survives a cold machine wash and comes out better than it went in. A thin blend holds a factory press instead, which is a different garment with different rules. The Italian linen shirts buyers guide explains how to tell the two apart before you buy.

What are the three things that ruin linen?

Before we get into the correct routine, here are the three moves that will kill a linen shirt. If you avoid these, you're most of the way there.

The never and always lists above are the shortest possible version of linen care. If you stopped reading here, you'd already do better than most people. But the details matter, so let's go through the actual routine, step by step.

How do you wash a linen shirt step by step?

1. Check the care label first. Every linen garment is slightly different depending on how it was finished. Most 100% linen shirts are machine washable on cold, but some brands pre wash their linen and some don't, which changes the guidance. If the label says cold, gentle cycle, follow it. If it says hand wash only, take that seriously. Ours are machine washable, cold, gentle cycle, always.
2. Turn the shirt inside out. This one small step protects the outer surface of the fabric from friction against zippers, closures, or the drum of the machine. It reduces the small pilling and fading that shows up after the tenth or fifteenth wash. Close the shirt fully first, then flip it inside out.
3. Cold water, gentle cycle, mild detergent. Cold water is non negotiable. Hot water shrinks linen fibers and fades color faster than anything else you can do. Use a mild liquid detergent, one that's designed for delicate fabrics, not a heavy powder with brighteners. Avoid bleach entirely. It weakens linen fibers and shortens the life of the shirt significantly.
4. Wash with similar colors and similar weights. Linen absorbs dye more than synthetic fabrics do, so a new dark linen shirt can bleed color on lighter items in the first two or three washes. Wash whites with whites, darks with darks. Also try to avoid throwing your linen shirt in with heavy items like jeans or towels. The friction can pull threads and stress the fibers.
5. Never overload the machine. Linen needs room to move in the drum. If you cram it in with a full load, it comes out more wrinkled than it needs to be, and the fibers don't rinse cleanly. Give it space. Half full is better than three quarters full.
6. Skip the dryer if you can. The dryer is where linen goes to die. High heat is the number one cause of shrinkage. If you must use a dryer, use the lowest heat setting and pull the shirt out while it's still damp. Then hang it or lay it flat. If you can, air dry from the start. It takes a few hours in a well ventilated spot.

Step	Santoli Napoli 100% linen	Never do
Wash	Machine wash cold, gentle cycle, mild detergent	Hot water, bleach
Dry	Hang damp on a wide hanger, air dry	Tumble dryer, heat breaks flax down over years
Soften	Let wear and washing do it	Fabric softener, it coats the fiber and kills moisture wicking
Press	Iron slightly damp on medium steam, inside of the collar outward	Press a dry, cold or dirty shirt

How should you air dry linen?

Air drying isn't just skipping the dryer. Where and how you dry the shirt affects how it looks when it's ready to wear.

Hang the shirt on a padded or wooden hanger, closed at the top so the collar keeps its shape. Don't hang it in direct sunlight for hours, since strong sun will fade the dye, especially on darker shirts. A shaded outdoor spot with airflow is perfect. Indoors near an open window or a fan works just as well.

If the shirt comes out of the wash a little stiff at first, don't panic. Linen has a natural stiffness that softens the minute you wear it. A slight breeze while it dries helps the fabric relax as the water evaporates.

Never lay a wet linen shirt flat on painted wood or a colored towel. Linen absorbs color from other surfaces when it's wet.

Should you iron linen?

Ironing linen is a personal choice, and there's no wrong answer. Italian men do iron their linen, often carefully, and then wear the shirt until the day puts the creases back. Both things are true at once, the press and the crease.

Linen wrinkles. That's what real linen does. If you buy a linen shirt that doesn't wrinkle, it's probably not 100% linen. The wrinkles are a feature, not a flaw. Many people, especially if you're going for a Mediterranean summer look, wear their linen shirts with the natural creases and love them that way.

If you want a crisper look, iron the shirt while it's still slightly damp. Set the iron to medium steam and work from the inside of the collar outward. Iron on the reverse side to avoid shine marks on the fabric. Don't press hard. Let the iron and the moisture do the work. If the shirt is already fully dry, spritz it with water first or use the steam setting.

Never iron a dirty shirt. Heat locks stains into linen fibers permanently.

Wrinkling is the proof, not the problem. A shirt that comes out of the wash flat is usually holding a press from a synthetic blend rather than behaving like flax. Our full answer on that sits in do linen shirts wrinkle, and the case for the fiber in the first place is in why wear linen.

How do you fix a shrunk linen shirt?

If you already made the hot water mistake, don't throw the shirt out. There's a chance you can recover some of the size.

Fill a sink with lukewarm water and add a small amount of mild fabric conditioner or hair conditioner. Soak the shirt for 30 minutes. Then gently stretch the fabric back toward its original shape while it's still wet. Don't pull hard, just guide it back. Lay it flat to dry, reshaping as it dries.

The conditioner soak won't work for extreme shrinkage, but for mild shrinkage from a single hot wash, it can bring back most of what you lost.

How should you store linen?

Linen prefers to breathe. Store it hanging if you have closet space, or folded loosely in a drawer with room to move. Avoid stuffing linen shirts into tight drawers where they compress into hard creases that are difficult to remove.

Cool and dry is the rule. Direct sun through a window will fade colors even in storage. If you're storing linen for the off season, wash it clean first, since stains and body oils darken and set over months in storage.

Hanger width matters more than most people expect on linen. A wide wooden hanger holds the shoulder line of a Santoli Napoli shirt such as Sand Beige in the Italian collar or Sand in the mandarin collar, both $139. A thin wire hanger digs two points into damp linen and leaves marks that take a press to remove.

How often should you wash a linen shirt?

Less often than you think. Linen is naturally resistant to bacteria and odor, and it airs out well between wears. If you wore the shirt for a few hours in mild weather and it looks and smells clean, hang it up overnight and wear it again.

Over washing shortens the life of any garment. A well made linen shirt might only need washing after two or three wears, unless you sweated heavily or spilled something on it. Spot clean small marks with a mild soap and cold water before you commit to a full wash.

Linen drawstring pants follow the same routine as the shirts. Pure White linen drawstring pants at $99 wash cold, hang damp, and never see the dryer. Fit changes how often a shirt needs washing too, since a shirt that sits off the body breathes better than one pulled tight, and how a linen shirt should fit covers that. If you are still choosing a shirt, the buyers guide compares weight, collar and construction.
