How to Wash Corduroy
Corduroy's cut pile rows (wales) are structurally different from the ground weave — heat causes them to shrink at different rates, flattening and distorting the pile permanently. Cold wash inside-out, no tumble dryer, steam rather than iron. The pile can be restored with steam if it deflects; it cannot be restored if it is heat-set flat.
The Chemistry
Corduroy and velvet are both cut pile fabrics, but their construction and failure modes differ in important ways that affect how they should be washed. In a cut pile fabric, extra yarns are woven into the base fabric and then cut at the top, leaving a surface of upstanding fibre tufts. In velvet, this pile is arranged uniformly across the fabric surface. In corduroy, the pile tufts are arranged in parallel rows — the wales — separated by flat ground weave channels running the length of the fabric. The visual effect is the characteristic ribbed surface with its directional play of light and colour. The primary structural concern with corduroy in washing is differential shrinkage. Corduroy is almost always woven with a cotton ground weave. Cotton shrinks from heat and agitation — the cellulose chains relax from their elongated spinning tension back toward a more compact equilibrium when the hydrogen bonds holding them extended are broken by heat and water. The cut pile tufts in standard cotton corduroy will shrink along with the ground weave. However, the pile and the ground weave are structurally different: the pile is a dense assembly of cut fibres with their ends free, while the ground weave is a conventional interlocked woven structure. They absorb water at different rates and dry at different rates. Under heat from a tumble dryer or a direct iron, these two components shrink and contract at different rates. The result is puckering, distortion of the wale rows, or permanent compression and matting of the pile tufts. The second important structural feature is pile direction. Corduroy pile tufts all lean in one direction (a consequence of how the fabric is cut during manufacture). Running your hand up the fabric (against the pile) versus down the fabric (with the pile) produces different visual and tactile effects — "against the pile" appears slightly lighter and has more drag; "with the pile" is darker and smoother. After washing and drying incorrectly (especially tumble drying), the pile tufts can dry in a deflected position or in mixed directions, producing uneven sheen and a matted appearance. This is reversible (steam and brush while still slightly warm will restore pile direction) but only if the tufts have not been thermoplastically set in the wrong position. The third issue is the susceptibility of corduroy to sheen damage from direct pressure. Ironing directly on the pile side of corduroy — exactly like ironing directly on velvet — crushes the pile tufts and creates a permanent shiny glazed patch where the tufts have been thermoplastically bonded flat. Cotton corduroy has no Tg in the usual sense, but the mechanical compression under the weight of an iron while hot is enough to permanently crush the pile structure. Always iron corduroy from the reverse, using a terry cloth towel or another piece of corduroy as a protective layer. Narrow-wale corduroy (more wales per inch) has thinner, more densely packed pile tufts and is more susceptible to permanent pile distortion than wide-wale. Micro-wale corduroy is extremely fine and approaches the fragility of velvet in some respects. Wide-wale corduroy (4–8 wales per inch) is the most robust type. Stretch corduroy contains elastane in the ground weave. This introduces the same temperature ceiling as all elastane-containing fabrics: above 75–80°C, the polyurethane-polyurea polymer of elastane permanently loses elastic memory. Cold wash (30°C maximum) is required for stretch corduroy. Corduroy generates significant static electricity in its dry state — the pile surface structure and cotton or synthetic composition creates ideal conditions for electrostatic charge buildup. This static strongly attracts lint, pet hair, and dust. Washing does not permanently remove this tendency; an anti-static spray or hanging in a slightly humid environment helps. The lint attraction is structural, not a product of washing.
Step-by-step
- 1
Check the wale count and fibre content — these determine the temperature ceiling
Wide-wale cotton corduroy (4–8 wales/inch): cold to 30°C machine wash. Standard cotton corduroy (10–16 wales/inch): cold to 30°C. Narrow-wale or micro-wale (20+ wales/inch): cold hand wash preferred; maximum 30°C gentle machine. Stretch corduroy (contains elastane): cold 30°C maximum — no exceptions. Polyester or poly-cotton corduroy: cold 30°C. Check the label for fibre content and follow the lower temperature if in doubt.

Turn corduroy inside-out before washing — this protects the pile from direct agitation
Turning inside-out before machine washing reduces direct contact between the pile tufts and the drum, agitator, and other garments. This minimises pile-on-pile friction that can cause tufts to deflect and mat. For dark corduroy, inside-out washing also reduces fading by keeping the pile surface away from direct agitation. Empty pockets, fasten any buttons or zip, and close all fasteners before loading.

Cold water, gentle or delicate cycle, mild detergent
Cold water (30°C maximum) is the critical parameter for corduroy. Higher temperatures cause differential shrinkage between the pile and the ground weave, distorting the wales. Gentle or delicates cycle reduces agitation, which helps maintain pile direction. Standard liquid detergent is appropriate — powder can leave residue in the pile tufts. Avoid fabric softener: it reduces the pile's ability to stand upright and coats the tufts, causing faster future lint attraction.

Remove promptly after the wash cycle — shake gently to restore pile direction
Remove from the machine as soon as the cycle ends. Leaving corduroy bunched in the drum compresses and deflects the pile in random directions as it starts to cool. Remove and give the garment a gentle shake — this helps the pile tufts begin to stand upright in their correct direction while the fabric is still slightly damp and the pile has maximum flexibility. If you can see areas where the pile has deflected, gently brush with a soft-bristle brush while still slightly damp.

No tumble dryer — hang to dry or lay flat
Tumble drying corduroy is the most reliable way to permanently flatten or distort the pile. The combined heat, agitation, and compression in a tumble dryer is ideal for thermoplastically fixing the pile tufts in a compressed, mixed-direction state. Hang corduroy on a padded hanger (not a thin wire hanger that will leave marks in the shoulders) or lay flat on a clean towel. Avoid direct sunlight or direct heat. Allow to dry at room temperature. Once completely dry, the pile direction will be set — brush gently with the pile direction to even out any minor inconsistencies.

If ironing is needed, use steam and iron from the reverse only
Never iron directly on the pile side of corduroy — the weight of the iron crushes the tufts and the heat sets them flat, creating a permanent shiny patch. If the garment needs pressing, place it pile-down on a thick terry towel or another piece of corduroy (pile-to-pile), and iron from the reverse on low to medium heat. Alternatively, use a hand steamer held 2–3cm above the pile surface to relax wrinkles and refresh the pile direction without contact. Move the steamer with the pile direction.

Frequently asked questions
Can you put corduroy in the tumble dryer?
No. Tumble drying corduroy permanently compresses and mat-flattens the pile tufts through a combination of heat, mechanical agitation, and compression. Once the tufts are thermally set flat in the dryer, the pile cannot be fully restored. Minor deflection from damp handling can be reversed with steam and gentle brushing, but dryer-flattened corduroy is permanently damaged. Always hang corduroy or lay it flat to dry at room temperature.
Can you iron corduroy?
Never iron directly on the pile side of corduroy — the iron crushes the pile tufts and the heat sets them flat, creating a permanent shiny glazed patch. If pressing is necessary, place the garment pile-down on a thick terry towel and iron from the reverse on low to medium heat. The terry cloth buffers the pile tufts and prevents compression. A hand steamer held 2–3cm above the pile surface is the safer option: it relaxes wrinkles without any contact pressure.
Why does corduroy attract so much lint?
Corduroy's cut pile surface generates and holds static electricity, which attracts lint, pet hair, and dust. The pile texture also provides more surface area for lint to catch and cling to compared to a flat-weave fabric. This is a structural property of corduroy — it cannot be permanently removed by washing. Keep corduroy garments away from towels, fleece, and synthetic fabrics in the wash and in storage. A lint roller after each wear is the practical management approach.
How do you restore flattened corduroy?
If the pile has been flattened by compression (sitting, pressure) but not by heat-setting (tumble dryer or direct iron), steam can often restore it. Hold a clothes steamer 2–3cm above the pile surface and move it steadily with the pile direction. While the fabric is still warm and slightly damp from the steam, gently brush the pile with a soft clothes brush in the natural pile direction. This coaxes the tufts back to an upright position. Repeat as needed. If the pile has been heat-set flat by a dryer or direct iron, this process has limited effect — the tufts are bonded in the flattened position.
