Can You Wash Blackout Curtains or Dry Clean Them?

TLDR;

Yes, most blackout curtains can be either machine washed or dry cleaned, but it depends on the fabric type and care label instructions. Always check the tag first—some materials like velvet or lined curtains may require professional dry cleaning to avoid damage.

What Are Blackout Curtains and Why They Need Special Care

Blackout curtains are specially designed to block light and improve energy efficiency, but that functionality depends heavily on their material and construction.

• Made from multiple layers: Often includes decorative fabric, a foam or rubberized backing, and sometimes a thermal liner
  
• Designed to block light, insulate, and add privacy
  
• Common materials: Polyester, triple weave fabric, cotton blends, velvet, or silk
  
  

Why Do Blackout Curtains Require Extra Care?

• The blackout coating or lining can break down or peel if cleaned incorrectly
  
• Some fabrics shrink or warp with heat and moisture
  
• Cleaning the wrong way can permanently damage the drapes' light-blocking ability
  

Read Before You Wash: Check the Curtain Label

Before doing anything, look at the care tag attached to your blackout curtains.

• The care label offers specific cleaning instructions for your curtain type
  
• Symbols may indicate machine wash, hand wash, or dry clean only
  
• “Dry Clean Only” means the fabric or backing could be damaged by water or agitation
  
  

Key Symbols to Recognize

• Tub with water: Machine washable
  
• Hand in tub: Hand wash only
  
• Circle: Dry clean only
  
• X over a tub or circle: Do not wash or dry clean
  
  

If the label is missing:

• Research the fabric online or refer to the purchase source
  
• When unsure, treat the curtains as delicate and avoid machine washing
  

Can You Machine Wash Blackout Curtains?

Yes, many blackout curtains can be machine washed, but only if the care label permits.

Machine-Safe Materials:

• Triple-weave polyester
  
• Unlined or lightly lined curtains
  
• Synthetic blends
  
  

Machine Washing Tips:

• Use cold water and a gentle cycle
  
• Select low spin speed to prevent damage
  
• Choose a mild detergent, free of bleach or brighteners
  
  

How to Machine Wash Blackout Curtains (Step-by-Step):

1. Remove dust with a vacuum or soft brush
   
2. Fold or roll curtains gently to prevent creases
   
3. Place in mesh laundry bag (optional for extra protection)
   
4. Set washer to cold, gentle, low spin
   
5. Use a small amount of gentle detergent
   
6. Run a short rinse cycle
   
7. Hang to dry (never use a dryer unless label says it's safe)
   

Hand Washing Methods for Delicate Curtains

Some blackout curtains—especially those with heavy or sensitive linings—should be hand washed.

When to Hand Wash:

• If your label says hand wash only
  
• If you're unsure of fabric sensitivity
  
• When dealing with light dirt or odor
  
  

Hand Washing Process:

• Fill a large tub or sink with cold water
  
• Add a small amount of mild detergent
  
• Submerge the curtain and let soak for 10–15 minutes
  
• Gently agitate without twisting or wringing
  
• Drain and rinse with cool water
  
• Press water out using a towel, then hang to air dry

Spot Cleaning for Minor Stains

When full washing isn't needed, spot cleaning is effective for isolated marks.

How to Spot Clean Blackout Curtains:

• Mix warm water with a few drops of mild detergent
  
• Dab the stain with a soft cloth or sponge—do not scrub
  
• Rinse area with a damp cloth and blot dry
  
  

What Can Be Safely Treated:

• Grease stains: Use dish soap
  
• Pet messes: Use enzyme-based cleaners
  
• Mold or mildew: A vinegar-water solution (test on hidden spot first)
  
  

Avoid using:

• Harsh chemicals
  
• Abrasive brushes
  
• Excessive moisture that can leave water rings
  

When Should You Dry Clean Blackout Curtains?

Dry cleaning is recommended when:

• The label states “Dry Clean Only”
  
• Your curtains are made of silk, velvet, or wool
  
• They have rubber backing or decorative elements like embroidery
  
  

Why Some Curtains Shouldn’t Be Washed at Home:

• Delicate fabrics shrink, warp, or lose shape
  
• Foam linings can dissolve or peel in water
  
• Heavier drapes may be too cumbersome for home cleaning
  
  

What Does a Dry Cleaner Do?

• Uses non-water-based solvents to clean fabrics
  
• Applies controlled heat and care techniques
  
• Ensures fabric structure and blackout backing remain intact
  
  

If you need dry cleaning:

• Search “dry clean blackout drapes near me”
  
• Choose a cleaner experienced with lined or blackout fabrics
  

Drying Your Curtains: Air Dry vs. Machine Dry

Never tumble dry blackout curtains unless the care label specifically says it’s safe.

Why Machine Drying Is Risky:

• High heat can melt or crack the blackout coating
  
• Fabric may shrink or become misshapen
  
  

Best Air Drying Practices:

• Hang over a shower rod or laundry line away from direct sun
  
• Spread flat on a clean towel or drying rack
  
• Roll a towel into pleats to reduce wrinkles before hanging
  

Ironing and De-Wrinkling Tips

Creases are common after washing blackout curtains.

Can You Iron Blackout Curtains?

Yes—but with care. Always iron on the fabric side, not directly on the lining.

Ironing Settings:

• Use low to medium heat
  
• If unsure, place a pressing cloth between iron and fabric
  
  

Steamer vs. Iron:

• Steamers are ideal for hanging curtains
  
• Less direct contact means lower risk of damage
  

How to Maintain Blackout Curtains

Routine maintenance keeps blackout curtains fresh and long-lasting.

Weekly/Monthly Curtain Care:

• Vacuum regularly using a brush attachment
  
• Shake out dust when you open windows
  
• Use liners to reduce direct exposure to sunlight and dirt
  
• Air out monthly to prevent odor buildup
  
• Close blinds behind curtains to reduce UV damage

Choosing the right curtain color also plays a role in longevity and aesthetic appeal, especially for spaces like dining areas—see our guide to Curtain Colors for Dining Rooms for stylish, timeless ideas.

Common Problems and How to Fix Them

Even with careful cleaning, issues can arise.

After Washing:

• Lingering smells: Air out for a few days, use fabric spray if needed
  
• Shrinking: Iron gently while still damp to stretch back
  
• Stiffness: Rub gently with hands or add fabric softener in rinse
  
  

Repair Tips:

• Loose grommets or rings: Sew or glue reinforcement
  
• Peeling lining: Apply fabric glue or take to a professional
