The fastest way to ruin blackout curtains is a hot wash followed by a tumble dry, which cracks the light-blocking coating and leaves pinholes that glow at 6 a.m. That backing is the whole reason you bought them, so it dictates every cleaning choice you make. Before you sort out your window treatments, it’s worth getting the rest of the room dialed in too, from best gallery wall frames to a best console table for entryway, a best large floor mirror, the right best wall mirror for living room, and a best table lamp for living room.
Can You Machine Wash Blackout Curtains?
It depends on the backing. Blackout fabric comes in two builds, and they behave very differently in water. Coated panels have a foam-acrylic layer painted onto the back, and these are the ones most likely to crack, peel, or flake if you machine wash them at all. Woven “triple-weave” blackout panels block light through dense fabric layers instead of a coating, so they handle a gentle cycle far better.
Check the care tag first. If it says hand-wash or spot-clean only, believe it. For woven panels rated machine-safe, use cold water (under 30°C / 86°F), the gentle cycle, and a mild liquid detergent with zero bleach. Wash one or two panels at a time so they aren’t crammed against each other.
Never wring them out. Twisting a 84-inch panel puts stress on the seams and backing that no fabric fully recovers from. Skip the dryer completely, even on low, since heat is what turns a flexible coating brittle. Owner reviews aggregated on Apartment Therapy repeat the same complaint over and over: the curtains were fine until someone dried them once.
If you’re unsure which build you own, run your thumb across the back. A rubbery, slightly tacky surface means coated. A soft, textile feel means woven.
How Do You Spot-Clean Without Wrecking the Coating?
Start local. Most stains and marks don’t need a full wash, and every full wash shortens a curtain’s life. Blot the spot with a cloth dampened in cool water and a drop of dish soap, working from the outside of the stain inward so you don’t spread it. Press, don’t rub. Rubbing drives grime deeper into the weave and can abrade a coated back.
For grease or makeup marks, a paste of baking soda and water sits on the stain for 15 minutes, then lifts away with a damp cloth. Keep all of this on the front face when possible and treat the coated side gently. GREENGUARD-certified fabrics tolerate mild cleaners, but harsh solvents can break down both the coating and any low-emission treatment the panel carries.
Try any cleaner on a hidden corner first, like the bottom hem behind the fold. Wait five minutes and check for color bleed or a dull patch. This ten-second step saves the whole panel.
Rinse the treated area with a second cloth dipped in plain water so no soap residue dries into a ring. Then let it air-dry flat or hang it right back on the rod. A quick spot-clean like this handles 80% of everyday marks. No washer required.
How Do You Remove Dust, Wrinkles, and Odors?
Dust is the real enemy, and it builds up faster than most people think. Vacuum both sides monthly with an upholstery brush attachment on low suction, running top to bottom in long strokes. This alone keeps allergens down and stops the gray film that makes light panels look tired. A handheld vacuum works fine for a quick weekly pass.
Wrinkles need heat handled carefully. Set an iron to its lowest setting, place a thin cotton pressing cloth between the iron and the fabric, and work the front face only. Direct heat on a coated back will melt it. A handheld garment steamer is the safer bet: hold it 6 inches away and let the steam relax the fibers without contact.
For odors, skip the fabric spray and start with air. Hang the panels outside on a mild, dry day for a few hours. Baking soda helps too. Lay the curtain flat, dust a light layer over it, wait 30 minutes, then vacuum it off. That pulls out trapped smoke and cooking smells without adding perfume that just masks them.
Freshen, don’t drench. A steamer plus a monthly vacuum keeps most panels presentable for a year between deep cleans.
How Often Should You Clean and Store Them?
Vacuum monthly, spot-clean as needed, and deep-clean every 6 to 12 months, more often in a bedroom near a busy street where road dust settles fast. Kitchens and homes with pets sit at the shorter end of that range.
When you take panels down for a season, don’t fold them into tight creases that set permanently in coated fabric. Roll them loosely around a cardboard tube instead, or drape them over a wide padded hanger. Store in a breathable cotton bag, never a sealed plastic bin, which traps humidity and invites mildew on the backing.
Label the bag with the room and panel size so you’re not measuring an 84-inch drop against a 63-inch window next fall. Keep them somewhere cool and dry, away from direct sun that fades folded edges unevenly. A closet shelf beats a garage or attic every time.
Helpful Picks
These three panels all clear a 4.4-plus owner rating and use backings that survive careful cleaning better than budget coated versions. Start with the linen-look option if you want a softer face that spot-cleans easily, or the room-darkening sets if maximum light blocking matters more than texture.
Joydeco 100% Blackout Linen Curtains 84 Inch, 2 Panels Rod Pocket & Back Tab Thermal Insulated Drapes
Pros
- True100% blackout performance with dedicated liner layer
- Versatile dual-mount design fits both casual and tailored aesthetics
- Affordable price for a complete2-panel set with premium linen texture
- Wide range of size options from 63 to 120 inches in length
- Heavyweight fabric provides noticeable noise reduction and privacy
Cons
- Faux linen may not satisfy buyers expecting the softness of real linen fiber
- Limited to 52-inch panel width, so extra-wide windows may need additional panels
- Back tab style can be harder to slide open and closed compared to grommet curtains
These Joydeco curtains hit a sweet spot that is surprisingly hard to find: full blackout performance wrapped in a fabric that actually looks good. Most blackout curtains feel plasticky or flat, but the textured faux linen here gives rooms a warm, layered feel that reads much more expensive than the price tag suggests.
In a real room, the heavyweight drape falls nicely without bunching, and the natural linen color works as a neutral backdrop for just about any palette. The dual hanging system is a thoughtful touch. Use the rod pocket for a gathered, casual look or switch to back tabs for clean, tailored folds when you want something more polished.
If you want complete darkness and a designer-adjacent linen look without spending over $25 for two panels, this one delivers.
Styles it works with: Modern Farmhouse, Scandinavian, Coastal Casual, Transitional
Best placed in: Primary bedroom windows, nursery or kids' room, living room sliding door, home office with screen glare issues
May not suit: Ultra-modern or industrial spaces where slek gromet panels look more cohesive, or rooms with very wide windows (over 100 inches) where two panels alone will not provide full coverage
Buy it if:
- You need complete darkness for sleeping, shift work, or a nursery
- You want the look of linen curtains but need blackout performance behind them
- You prefer having two hanging style options so you can restyle without replacing curtains
Consider waiting if:
- You need a very specific color that is currently out of stock in your preferred length
- You want to compare seasonal sale pricing during Prime Day or Black Friday
Skip it if:
- You need sheer or light-filtering curtains that still let natural light through
- You strongly prefer grommet-top panels for easy sliding on a curtain rod

- Thick 225 GSM fabric provides solid light blocking and thermal insulation

Finding blackout curtains that actually block light without looking cheap or feeling flimsy is harder than it sounds. This MIULEE set stands out because you get four panels of genuinely thick 225 GSM fabric for less than most brands charge for two. The matte finish and consistent black color on both sides give them a clean, modern drape that looks intentional rather than like a dorm room fix.
What really sets these apart for everyday living is the dual rod pocket design. You can secure the bottom to keep panels taut and neat, which is a small detail that makes a big difference in rooms where drafts or foot traffic cause curtains to shift. The ruffled header adds just enough softness to avoid the flat, industrial look some blackout curtains have.
If you want genuine room-darkening performance and full window coverage without spending more than $20, this one delivers.
Styles it works with: Modern Minimalist, Industrial, Contemporary, Scandinavian

- You want a longer drop length for floor-to-ceiling windows
Skip it if:
- You prefer grommet or tab-top curtains that glide easily for frequent opening and closing
- You need panels wider than 40 inches each to cover oversized windows with fewer panels

Frequently Asked Questions
Can you put blackout curtains in the dryer?
No. Heat is the single fastest way to crack a blackout coating and create light-leaking pinholes. Air-dry flat or hang them damp on the rod so gravity pulls out wrinkles as they dry.
Do blackout curtains lose their darkening ability after washing?
It depends on the backing and how you wash them. Woven triple-weave panels hold up well on a cold gentle cycle, while coated panels can lose 10 to 20% of their opacity if washed hot or wrung out. Cold water and no dryer keep the coating intact longer.
How do you clean blackout curtains without taking them down?
Yes, this is the smarter routine most weeks. Vacuum both sides with an upholstery brush, spot-clean marks with cool soapy water, and steam wrinkles with a handheld unit held 6 inches off the fabric. Full washes should be the exception, not the habit.
Can you machine wash 100% blackout curtains?
It depends on the care tag. Many woven blackout panels list a cold gentle cycle as safe, but foam-coated ones often say hand-wash or spot-clean only. When the tag is missing, treat the panel as coated and hand-clean it to be safe.
Will ironing damage blackout curtains?
Yes, if you iron the coated side or use high heat. Iron the front face only, on the lowest setting, with a cotton pressing cloth in between. A steamer avoids the risk entirely since it never touches the backing.
How do you get mildew smell out of blackout curtains?
No perfume spray needed. Air them outdoors for a few hours, then sprinkle baking soda, wait 30 minutes, and vacuum it off. Persistent mildew on the backing usually means the panel was stored in sealed plastic, so switch to a breathable cotton bag going forward.
How often should blackout curtains be deep-cleaned?
It depends on the room. Every 6 to 12 months works for most bedrooms, but drop to every 3 to 4 months near a busy street, in a kitchen, or in a home with shedding pets. Monthly vacuuming stretches the gap between deep cleans.
