How to Wash Curtains by Fabric Type (2026): Linen, Cotton, Velvet, Polyester, Blackout, Sheers, Silk, Wool

Before you touch a single panel, gather these eight supplies and set aside 45 minutes. The wrong tool costs more than the panel it ruins, and the wrong water temperature can shrink a 100% linen drape by 5% on the first cycle. That is a $400 mistake on a set of custom curtains.

Eight fibres, eight protocols, one universal rule: the sewn-in label wins every argument. This guide walks each fibre from linen through wool, gives you the water temperature, the drying method, and the ironing setting, then bridges into the honest answer for when the panel is just too far gone. The deeper deep-dives sit in the full curtain care hub for readers who want to go further.

Quick Reference: Wash Method by Fabric

Here is the deal: the label decides. Locate the sewn-in care tag on the header or side seam, cross-reference the international fabric care label symbols, then use this table as the shortcut for the eight fibres that cover roughly 95% of custom curtain fabrics shipped in the US.

Fabric	Wash method	Water temp	Drying & ironing
Linen (100%)	Cold gentle machine or hand	Cold, 30°C max	Line-dry damp, iron medium on damp
Linen blend (pre-washed)	Cold gentle machine	Cold, 30°C	Line-dry damp, low iron with cloth
Cotton (100%)	Cold gentle, hand first time	Cold to lukewarm, 30°C	Line-dry damp, iron high on damp
Velvet (cotton or silk)	Steam vertical or dry-clean	N/A (no water)	Steam only, never iron
Polyester & blends	Cold gentle machine	Cold, 30°C	Low tumble 15 min, iron low with cloth
Blackout (coated lining)	Spot-clean face only, never machine	Cool damp cloth	Air-dry flat, never iron
Sheers & semi-sheers	Mesh bag cold gentle	Cold, 30°C	Drip-dry rehang, iron cool with cloth
Silk	Hand wash or dry-clean	Cool	Roll-press towel, iron cool with damp cloth
Wool / wool blend	Cold soak only, never machine	Cold	Roll-press towel, air-dry flat

The table answers about 80% of decisions without further reading. The next eight sections handle the edge cases, the shrinkage math, and the reason your coated blackout lining is the panel most likely to die in a single cycle.

Linen Curtains – Wash & Care

100% linen shrinks. That is not a flaw, it is a fibre reality. Expect 3 to 5% shrinkage on the first wash, sometimes higher if the panel was not pre-washed at the mill. The workaround for buyers who want linen without the shrinkage headache is a blend: Two Pages Liz Linen runs 90% polyester and 10% linen at 140 gsm, pre-washed, and stabilises at under 2%.

Fibre content matters more than aesthetics when it comes time to wash. The Liz Linen Drape product page lists the composition and the pre-wash finish, both of which change what your washer settings should be. If the label reads “100% Belgian linen,” respect the shrinkage math. If it reads “polyester-linen blend, pre-washed,” you have room to breathe.

Water Temp

Cold gentle cycle, 30°C (86°F) maximum. Hot water is where the 3-5% shrink shows up on 100% linen, and it also sets any protein-based stains (wine, food, body oils) into the weave. Owner logs on Trustpilot consistently mention that the panels which held their drop after five years were the ones washed cold from day one.

Drying

Line-dry damp. Take the panel out of the machine before it goes fully dry, hang it on the rod while still slightly wet, and let gravity press out the creases as it finishes drying. This works on linen better than any other fibre because the weight of the wet fabric straightens the drop naturally.

Never tumble dry 100% linen. The agitation felts the surface fibres and the heat locks in shrinkage that a cold wash alone did not cause.

Ironing

Steam-press damp on medium heat, from the back, with a pressing cloth if the label is finicky. Dry-ironing a bone-dry linen scorches it: the fibre yellows at points of contact and the colour shift is permanent. If the panel came out of the machine crease-heavy, mist it lightly with a spray bottle before pressing.

Cotton Curtains – Wash & Care

Cotton is the most forgiving natural fibre in the guide. Raw 100% cotton shrinks 5 to 8% on the first wash, but pre-washed cottons and cotton blends stabilise at about 2%. Two Pages Isabella runs 60% cotton and 40% polyester at 150 gsm, which reads and behaves like a heavier cotton while dodging most of the shrinkage risk.

The wash rules are simpler than linen because cotton tolerates a hotter iron on the finish. Where linen wants a delicate press, cotton takes a high-heat pass on damp fabric and comes out crisp. That difference alone is why cotton panels look put-together longer than linen with the same wash frequency.

Machine or Hand

Cotton blends handle a gentle machine cold cycle from the first wash. 100% cotton benefits from a hand-wash for the first cycle to gauge how much shrinkage the panel actually delivers, then moves to gentle machine on subsequent washes. Cart simulation on the Two Pages configurator shows most cotton panel orders are blends, which skips the hand-wash prologue entirely.

Water Temp

Cold to lukewarm, 30°C maximum. Hot water sets stains, shrinks the fibre, and dulls colour on dyed cottons within three cycles. White 100% cotton is the only exception, tolerating 40°C for stubborn stains.

Drying

Line-dry damp, same as linen, and rehang immediately. Low tumble is permissible on cotton blends if the label allows, but never on 100% cotton: the heat locks in whatever shrinkage the cold wash did not.

Ironing

High heat on damp fabric with a shot of steam. Cotton is the one fibre in this guide that actually welcomes a hot iron, and the result is a crisper drape than any steamer produces. Owners who want the just-tailored look on their cotton curtains iron them once a year post-wash.

Cotton is where regular washing pays off in visible drape quality. If you want a fabric that looks better after twelve months of care than it did on day one, cotton blends are the answer, and the Isabella Heavyweight Cotton Drapery is the collection Two Pages built for that use case.

Velvet Curtains – Wash & Care

Three velvets, one shared rule: never wash cotton or silk velvet in water. Cotton velvet, silk velvet, and polyester velvet are three different animals, but the pile crush point is a universal risk. Water flattens the pile permanently on cotton and silk velvet, and polyester velvet has only slightly more tolerance. Two Pages Birkin runs cotton velvet at 500 gsm, which is exactly the weight this care protocol was written for.

Steam Only

A vertical handheld steamer held 6 inches from the fabric, worked from the back of the panel, opens the pile and relaxes creases without any pile contact. This is the technique the Two Pages product specification recommends for the Birkin collection, and it is the same protocol used by hotel housekeeping crews on velvet drapes.

Never press velvet with an iron, and never touch a steam head directly to the fabric. Both crush the pile in seconds and neither crush recovers.

Dry Clean Frequency

Once every two to three years maximum. Over-dry-cleaning strips natural oils from the pile and dulls the sheen, which is exactly the property that made you pay for velvet in the first place. Owner feedback on Trustpilot consistently mentions that velvet panels dry-cleaned every five years still read as new, while panels sent yearly show visible sheen loss by year three.

Spot Treatment

Spills call for a blot, never a rub, with a dry-cleaning solvent on a white cloth, working from outside in. Rubbing pushes the spill into the pile and spreads the stain. Blotting lifts it out. If the stain is water-based, resist the urge to add more water: it makes everything worse.

Polyester & Blends – Wash & Care

Polyester is the most washer-friendly synthetic in the guide. Cold gentle cycle, mild detergent, low spin, and the panel comes out ready to rehang with only minor pressing. Blackout-coated polyester is the exception (see the blackout section below), but standard polyester and polyester-linen blends like Two Pages Liz Linen are the panels this article can most confidently tell you to machine wash.

Machine Cold OK

Gentle cycle, cold water, mild pH-neutral detergent, low spin. Polyester tolerates repeat washing better than any natural fibre and can go through 15 to 20 cycles across its lifespan without visible degradation. That is why nursery, kitchen, and playroom curtains are almost always polyester blends: they take the abuse.

Drying

Low tumble 15 minutes maximum, or line-dry damp. Heat sets creases in polyester in a strange way, so the trick is to pull the panel out of the dryer while still slightly damp and rehang it immediately. Full-dry polyester on the rod holds creases that a hot iron will not fix.

Ironing

Low heat with a pressing cloth. Polyester scorches at cotton settings and the burn mark is permanent, so use the pressing cloth even on a familiar iron. A handheld steamer is the safer default for polyester, and it takes about half the time.

Blackout & Lined Curtains – Wash & Care

Real talk, the coating on your blackout lining is the reason it works, and it is fragile. A heavy blackout panel like the Two Pages Atlanta Room Divider (252 gsm polyester with a heavy blackout with a coated lining) is engineered to block 99% of light, but that light-blocking rating dies the moment the coating cracks. And the coating cracks in warm water. And in tumble dryers. Sewn linings and bonded linings behave differently, and the distinction changes everything about how you handle the panel.

Never Machine Wash Coated Blackouts

The coating cracks at temperatures over 40°C (104°F) and in tumble dryers. Once cracked, the coating flakes off in patches, the blackout rating drops from 99% to about 70%, and there is no way to restore it. The panel is done.

Spot-Clean the Face Fabric

A damp cloth, mild soap, patience. Work face-side only, protect the coated back with a dry towel underneath, and blot rather than rub. Owner feedback on Trustpilot for the Atlanta Room Divider collection mentions this exact protocol year after year: spot-clean, air-dry flat, rehang.

Sewn Lining vs Bonded Lining

Sewn linings can be separated. Bonded linings cannot. If the panel is a heavy blackout with a sewn-in (not glued or bonded) lining, unpick the seam, wash the face fabric on a cold gentle cycle, spot-clean the coated backer separately, then re-sew or clip the two layers back together. Bonded linings are a single unit: dry-clean or spot-clean only, and never attempt to separate them.

Sheers & Semi-Sheers – Wash & Care

Sheers are the easiest washables in the guide. Polyester voile, embossed polyester, and the embossed semi-sheer polyester Two Pages sells under the Florida collection all take a gentle machine cycle without complaint. The one universal rule is a mesh bag, because sheer weaves catch on machine drums and rip in ways that heavier fabrics do not.

Net Bag Cold Gentle

Fold the panel loose, drop it into a large mesh laundry bag, and run a cold gentle cycle with a small amount of mild detergent. Skip fabric softener: it coats the sheer weave and dulls the light-diffusion property that made you buy sheers in the first place.

Drip-Dry Rehang

Never tumble a sheer. The heat scorches polyester voile, and the tumble action can snag the weave against the drum. Hang the panel directly on the rod while still damp so gravity presses out wrinkles as it dries. This is the same technique used on linen but even more effective on sheers because the fabric is so light.

Iron Cool if Needed

Cool iron with a pressing cloth if wrinkles persist after drip-dry. Sheers scorch or melt at anything above the rayon setting, and the melt-mark is permanent (and visible from the room side against backlight). A cool handheld steamer is the safer default.

Silk Curtains – Wash & Care

Dupioni silk, silk-cotton blend, and faux silk are three different fibres with three different rules. The safest default across all three is dry-clean, and the safest default for buyers who insist on home care is hand-wash cool with a pH-neutral silk soap. Machine wash destroys silk in one cycle. Even the “silk setting” on a modern washer is optimistic.

Hand Wash Cool for Dupioni

Fill a bathtub with cool water and a pH-neutral silk soap. Submerge the panel, agitate gently by hand for 3 to 4 minutes, drain, rinse cool. Never wring, never rub. Roll the panel in a white absorbent towel to lift the water out, then air-dry flat.

Dry Clean for Silk Velvet or Complex Weaves

If it were my dupioni, I would pay the $30 dry-clean and move on. Silk velvet, jacquard silk, and any silk panel with intricate embroidery or contrast trim belong at the dry cleaner. DIY hand-wash risks water spotting on the lustre, and lustre loss is the one thing silk cannot recover.

Air Dry Flat

Never hang wet silk. The weight of the water distorts the weave permanently, and the panel dries with a stretched drop that no ironing fixes. Roll the panel in white towels to absorb, unroll onto a flat surface (a clean bed sheet on the floor works), air-dry flat, then iron cool with a damp pressing cloth.

Wool / Wool-Blend Curtains – Wash & Care

Wool curtain panels are rare in the US market and common in UK and luxury custom lines. Picture the panel folded in on itself in the drum, 30% smaller, felted for good: that is what a single spin cycle does to a wool curtain. It is the most fragile fibre in this guide by a wide margin.

Never Machine, Never Tumble

Any mechanical agitation felts wool permanently. Felting is not shrinkage that can be stretched back: the scales on the wool fibre lock into one another and the fabric becomes a dense, thick mat. A wool panel that goes into a washer at 40°C with a normal spin comes out unusable.

Cold Soak Only

Fill the tub with cold water and a wool wash detergent like Eucalan or Woolite. Submerge the panel, do not rub, do not agitate, let it soak for 10 minutes, drain, rinse cold. That is the entire wash. No scrubbing, no wringing, no spin.

Roll Press Flat Dry

Roll the panel in white towels to absorb, unroll onto a flat surface away from heat and direct sun, and let it air-dry flat. Never re-hang a wet wool panel: the water weight stretches the fabric out of shape, and unlike linen, it does not recover.

Common Mistakes to Avoid

Here is what wrecks a panel in one cycle. Six mistakes owners repeat across every fibre, each of which shortens panel life by one to three years. Skip these and the panels you already own outlast the marketing copy.

The others: chlorine bleach on any coloured fabric (strips dye in one soak), tumble drying blackout-coated linings (cracks the coating), ironing bone-dry linen at cotton settings (scorches the fibre), machine washing silk on “delicate” (frays the weave), and using fabric softener on sheers or velvet (coats the surface and dulls the property that defines both fibres).

The last common mistake is timing. Owners deep-clean their curtains once every three or four years instead of yearly, and by then the panel is asking for a full replacement rather than a wash. A yearly cycle on the schedule below adds two to four summers to the useful life of every panel in the guide.

When to Reorder vs Rewash

Coming back to the original question: care buys you extra years, not immortality. If after two proper wash cycles the panel still smells of mildew, sags at the header seam over an inch, or shows permanent colour shifts beyond 20% fade, the fibre is done. Cleaning is not the answer. Reordering is.

Three signs to stop washing and start looking at a replacement: trapped mildew odor that survives a full soak and dry, header sag over one inch that ironing does not correct, and colour fade over 20% compared to the swatch you kept from the original order. Two of the three means the panel is past its useful life. Three of the three means it should have been replaced last season.
