How To Wash Blackout Curtains

Blackout curtains work hard to block light and regulate temperature, so a careful cleaning routine keeps them hygienic and effective without ruining the blackout coating. This guide explains how to wash blackout curtains and how to clean block out curtains safely, when to machine wash, when to hand wash, and when to use professional dry cleaning. You will see exact temperatures, cycles, detergents, stain removal steps, drying rules, and ongoing curtain care so your curtains keep blocking light and looking sharp.

How To Wash Blackout Curtains Steps By Step

Yes, most blackout curtains can be cleaned, but the method depends on the fabric type and the care label. Remove all hardware, choose the gentlest suitable method, and always air dry in shade.

• Check the care label first. Follow the manufacturer’s instructions before washing to avoid damage.
• Remove hooks and rings. Take down the curtains and detach all hardware before washing.
• Pre-clean the fabric. Shake outdoors, then vacuum with a soft brush attachment to remove dust and pet hair.
• Machine wash only if permitted. Use a delicate cycle, cold or lukewarm water, mild liquid detergent, and a mesh laundry bag.
• Hand wash delicate or coated styles. Gently agitate, then rinse thoroughly to remove soap residue.
• Spot clean small marks. Dab with a mild detergent solution and a clean cloth.
• Air dry only. Hang in shade and keep coated surfaces from touching to prevent sticking. Never tumble dry.

Check The Care Label Before You Start

The label is your primary instruction. It tells you whether machine washing, hand washing, or dry cleaning is recommended for your curtain fabric.

• Fabric and construction: Triple-weave blackout fabrics are usually machine washable on a gentle cycle. Foam or rubber-backed blockout curtains and heavier fabrics often need hand washing or professional dry cleaning.
• Temperature icon: Treat cold as 20 to 30°C. If the label lists lukewarm, stay on the low side to protect the coating.
• Do-not symbols: A crossed dryer means no tumble drying. A crossed triangle means no bleach.
• Warranty note: Some manufacturers require professional cleaning for coated or delicate fabrics. Keep receipts if you choose professional dry cleaning.

What You Need

• Mild liquid detergent or a mild detergent solution
• Mesh laundry bag large enough for each panel
• Vacuum cleaner with a soft brush attachment and a lint roller for pet hair
• Microfibre cleaning cloths and a bucket for low-moisture wipe downs
• Clean towels to press out excess water
• A clothesline, rail, or shower rod for hanging curtains to air dry away from direct sunlight

Clean Blackout Curtains In A Washing Machine

Use these steps only if the label states machine washable. This section covers how to clean blackout curtains and washing blackout curtains safely.

Use a delicate or wool cycle with cold or lukewarm water, a mild liquid detergent, and low spin, then air dry in shade.

1. Remove dust and hardware: Detach rings and hooks. Shake outdoors, then vacuum the curtain fabric with a soft brush attachment to lift dust and dirt.
2. Bag each panel: Place one panel per mesh laundry bag to limit abrasion.
3. Choose settings: Delicate cycle, 20 to 30°C water, light load, and a gentle spin at about 600 rpm or less.
4. Dose detergent lightly: Use a small measure of mild liquid detergent. Avoid fabric softeners and optical brighteners.
5. Rinse well: An extra rinse helps stop residue that attracts dust.
6. Remove promptly: Lift out the curtains as soon as the cycle ends to minimise creasing.
7. Air dry completely: Hang on a line or shower rod. Keep coated faces from touching while drying to prevent sticking. Avoid direct sunlight.

Tip for top loaders: Use the gentlest program and consider stopping before a heavy spin to reduce stress on coated backings.

Hand Washing For Blockout Curtains

This section explains how to clean block out curtains with rubber or foam backings and more delicate curtains that are not suited to machine washing.

Gently agitate in cold water with a mild detergent solution, then rinse thoroughly to remove soap residue.

1. Vacuum first: Regularly dust to remove loose dirt and allergens. Use a lint roller to collect pet hair.
2. Prepare the bath: Fill a clean tub with cold water and a small amount of mild detergent.
3. Spot test: Test a hem or inner seam for colourfastness and coating stability.
4. Submerge the fabric face: Keep the coated side from prolonged soaking. Gently agitate for 5 to 10 minutes.
5. Rinse completely: Drain and refill with cold water. Press water through the fabric until the water runs clear.
6. Remove excess water: Lay the panel on a towel, roll, and press to lift moisture. Do not wring.
7. Hang to dry: Hang from the header so the weight helps the curtain hang straight. Keep coated faces separated while drying.

Low Moisture Cleaning For Delicate Curtains

When soaking is not recommended or the label is unclear, use a low-moisture wipe to freshen the fabric face without saturating the coating.

1. Mix a cleaning solution: A few drops of dish soap or laundry soap in cold or lukewarm water.
2. Wipe the fabric face: Dip a microfibre cloth, wring almost dry, and wipe from top to bottom.
3. Rinse cloth and repeat: Follow with a clean damp cloth to remove residue.
4. Dry immediately: Pat with a towel and allow airflow to prevent lingering odours.

Spot Cleaning And Stain Removal

Treat stains promptly so they do not set into the curtain material.

• General marks: Blot with a mild detergent solution using a clean cloth. Dab, do not rub.
• Grease stains: Work a small amount of gentle detergent on the fabric face, then rinse with a damp cloth.
• Tannin or food spots: Cold water first, then a mild solution.
• Avoid: Harsh chemicals, chlorine bleach, and aggressive scrubbing, which can damage rubberised backings and the blackout coating.

Drying And Wrinkle Care

Drying is where coatings are most at risk.

• Air dry only: Never tumble dry. Hang to air dry completely in bright shade with good airflow.
• Keep coatings from touching: Space panels so coated backs do not stick to each other while drying.
• Avoid direct sunlight: Sun can embrittle coatings and fade delicate fabrics.
• De-crease safely: Steam the fabric face from 20 to 30 cm, moving continuously, or use a warm iron with a pressing cloth on the fabric face only. Do not iron the blackout side.

Types Of Blackout Curtains And How To Clean Them

Blackout curtains are designed to block light and support a cooler, quieter room, but cleaning rules vary by fabric type and construction.

• Triple-weave blackout (no coating): Usually safe for machine washing on a gentle cycle with cold water and mild detergent.
• Foam or rubber-backed blockout: More delicate fabrics that benefit from hand washing or professional dry cleaning. Avoid harsh soaps and detergents that can degrade the coating.
• Heavy fabrics such as velvet or lined cotton: Often require careful handling and may be better suited to dry cleaning.
• Portable blackout curtains: Handy for travel or camping to block light. Follow the label; most clean with low-moisture wiping or gentle hand washing.

Curtain Care Between Washes

Clean curtains perform better for longer. A consistent routine preserves blackout performance and appearance.

• Vacuum monthly: Use a soft brush attachment to reduce dust mites, pet dander, and allergens. This also limits odours absorbed from the environment.
• Dust management: Wipe window sills to stop moisture and mould transferring to the fabric.
• Freshen regularly: Air rooms after cooking and in humid weather to reduce lingering odours.
• Annual deep clean: Wash or professionally clean once a year to maintain light-blocking capacity.
• Treat stains early: Prompt spot cleaning prevents marks becoming ingrained and difficult to remove.

Dry Cleaning And When To Use It

Choose professional dry cleaning when the label specifies dry clean only, when coatings are fragile or peeling, or when stains resist home methods. Tell the cleaner your curtains are blackout or blockout so they select a gentle process compatible with coated linings and delicate fabrics.
