How to Wash Linen Shirts — The Complete Care Guide

The complete guide to washing linen shirts — temperature, cycle, drying, ironing, and storage.

Linen shirts are easier to wash than most people expect. The reputation for difficulty comes from lower-grade linen — short-staple cloth that stiffens, shrinks, or loses its drape in the wash. Long-staple Belgian linen behaves differently. It improves with washing. The fibre softens rather than degrades, and the drape becomes more fluid over time rather than less.

The correct method:

“Belgian linen washed and stored correctly will last for decades. Washed correctly from the first time, it will be better by the tenth wash than it was by the first.”

— Pieter Petros, founder

Machine wash on a cool or warm cycle — 30 to 40 degrees Celsius. Linen does not require cold water, but temperatures above 60 degrees Celsius will cause shrinkage and may damage the fibre structure over repeated washes. A gentle or delicate cycle is ideal but not essential for Belgian linen — the long-staple fibre is robust enough to handle a normal cycle without damage.

Use a mild detergent. Avoid detergents with optical brighteners — these can affect the natural tone of linen colourways over time, particularly in the warmer shades like Dubarry and Roosewood Pink.

Do not use fabric softener. Linen does not benefit from softener and does not need it. Belgian linen softens naturally through washing. Adding softener reduces the natural moisture-wicking properties of the flax fibre — the very quality that makes linen the correct fabric for hot climates.

Drying: hang dry or tumble dry on low heat. Hanging is preferable — it allows the cloth to dry in its natural drape, which reduces the amount of ironing required and preserves the structure of the weave over time. If tumble drying, remove while still slightly damp to prevent over-drying.

Ironing: linen can be ironed on a medium-high heat while damp for a pressed finish. Or it can be left with its natural texture — the relaxed surface of air-dried linen is part of the fabric's character, not a flaw. Many PP customers do not iron at all.

Storage: hang or fold loosely. Linen needs to breathe — avoid sealed plastic bags or vacuum storage. A breathable garment bag or an open wardrobe rail is correct.

Belgian linen washed and stored correctly will last for decades. Washed correctly from the first time, it will also be better by the tenth wash than it was by the first.
