Clean cellular shades — also called honeycomb shades or honeycomb blinds — with a soft brush or vacuum brush attachment for surface dust, compressed air to clear debris out of the honeycomb cells, and a barely damp cloth with mild soap for spot stains. Never submerge them in water, and never scrub the fabric. That's the short version. The rest of this guide covers exactly how to do each step correctly, what to do for stubborn stains, and the specific mistakes that permanently crush the pleats or void a warranty.
Why Cellular Shades Need Gentler Cleaning Than Other Blinds
The honeycomb structure that makes insulated cellular shades so effective is also what makes them fragile to clean the wrong way — the fabric is soft, pleated, and glued at each fold, not rigid like aluminum or PVC slats. A wood or faux wood blind can handle a damp wipe with no consequence. A cellular shade can't: too much moisture weakens the adhesive holding the honeycomb cells together, and any scrubbing motion flattens or "pills" the fabric permanently. For homeowners across the US, Canada, and Australia, preserving that honeycomb structure is key to maintaining both the look and the long-lasting insulation of the shades. Every step below is built around that one constraint. (If you also have other fabric window treatments in your home, check our guide on how to clean roman shades for similar gentle care instructions.)
Routine Dusting (Do This Weekly)
A weekly pass with a soft brush, microfiber cloth, or your vacuum's brush attachment on low suction is the single most effective thing you can do for a cellular shade. Work in one direction along the pleats rather than back-and-forth — a back-and-forth motion is what causes pilling over time. If you're using a vacuum, keep it on the lowest suction setting and never remove the brush attachment, since bare suction can pull the fabric out of shape. Staying consistent with this weekly step is what prevents dust from settling in deep enough to need the more involved cleaning methods below.
Clearing Dust and Debris From Inside the Cells
Use a can of compressed air aimed into the open end of each honeycomb cell to push out dust, pollen, and the occasional trapped insect that a surface wipe can't reach. Lay a drop cloth or newspaper underneath first to catch what comes out. A hair dryer on a cool, no-heat setting works as an alternative — never use a warm or hot setting, since heat can soften the glue that holds the honeycomb structure together.
Spot Cleaning Stains
For a stain, blot — don't rub — with a lint-free cloth barely dampened in lukewarm water and a drop of mild dish soap, working from the outer edge of the stain toward the center. Rinse the spot with a second cloth dampened in plain water to remove soap residue, then blot dry with a dry cloth. Once the area is dry, leave the shade fully lowered or raised (whichever position stretches the fabric) for a few hours so the pleats settle back into their original shape.
Can You Wash Cellular Shades in the Bathtub?
No — fully submerging or soaking cellular shades, including in a bathtub, is one of the most common ways people permanently damage them. Soaking saturates the adhesive that holds the pleats together, can cause the fabric layers to separate (delaminate), and lets internal metal components corrode. If dusting and spot cleaning haven't handled a heavily soiled shade, the safer next step is a professional ultrasonic cleaning service rather than a bathtub — ultrasonic cleaning uses sound-wave-generated bubbles to lift dirt out of the cells without soaking the fabric.
Cleaning Cordless Cellular Shades Without Taking Them Down
Cordless cellular shades can be cleaned fully in place — dust, compressed air, and spot cleaning all work the same way whether or not the shade has a cord, and there's no need to remove a cordless shade from its brackets for routine cleaning. The only difference with cordless models is handling: extend the shade fully before dusting so the pleats sit flat and even, making it easier to work top to bottom without missing folds.
Cleaning Blackout Cellular Shades
Blackout cellular shades use an internal lining or metallic layer to block light, and that lining is more moisture-sensitive than standard light-filtering fabric, so keep water use to an absolute minimum. Dry dusting and compressed air are the primary methods for blackout shades; if spot cleaning is unavoidable, use the least amount of moisture that will lift the stain, and avoid pressing hard enough to push moisture through to the lining.
What Never to Do
- Never submerge or soak the shade — this is the single most damaging mistake, covered above, and applies to every fabric type including blackout.
- Never use bleach, ammonia, or harsh chemical cleaners — these discolor the fabric and break down its finish over time.
- Never scrub — rubbing motion pills the fabric and can permanently crush the pleats.
- Never machine wash or dry — the agitation and heat destroy the honeycomb structure.
- Never use a hot hair dryer, radiator, or direct heat to dry a damp spot — heat can melt the adhesive.
Maintenance Schedule: How Often to Clean
| Task | Frequency |
|---|---|
| Light dusting | Weekly |
| Vacuum with brush attachment | Monthly |
| Spot-clean visible stains | As needed |
| Deep clean / inspect for buildup in cells | Quarterly |
| Professional ultrasonic cleaning | Every 1–2 years, or for heavy buildup |
Kitchens and Bathrooms Need More Attention
Steam and condensation are the enemy here. If a shade doesn't fully dry out between uses, you'll eventually get mildew spotting on the fabric. Wipe off visible moisture as soon as you notice it, and plan on dusting more often than you would in a bedroom — humid air plus kitchen grease means dust sticks harder and faster.
A Couple of Product-Specific Quirks
TDBU shades have two headrails instead of one, top and bottom, and people tend to only dust the top one because it's the one they see most often. Lower the top panel fully at least once during your cleaning routine and hit the bottom rail too — it collects just as much dust, it's just less visible. For more on how TDBU shades work, see our TDBU vs. Standard Cellular Shades guide. If your TDBU shade ever gets stuck or crooked, learning how to fix cellular shades by resetting the tension is a handy skill, or refer to our specific guide on what to do if your cordless blinds are stuck and won't go down.
Blackout fabric is thicker and layered compared to light-filtering fabric, so it hides dust a bit longer between cleanings. The tradeoff shows up if you ever need to spot-clean it: those extra layers take noticeably longer to air-dry, so go easier on the water than you would with a lighter fabric. See our Blackout vs Light Filtering Blinds guide for a full breakdown of fabric differences.
FAQ
How do you clean honeycomb shades?
Dust weekly with a soft brush or vacuum brush attachment, clear the inside of each cell with compressed air, and spot clean stains with a barely damp cloth and mild soap — never submerge them in water.
How to clean cellular shades at home without special equipment?
A microfiber cloth or soft brush for dusting and a damp cloth with a drop of dish soap for spot stains covers most cleaning needs; compressed air (sold for cleaning keyboards and electronics) handles debris trapped inside the cells.
Can you wash cellular shades?
You can spot clean them with a barely damp cloth, but you should never fully wash or submerge cellular shades in water — soaking damages the adhesive and can permanently warp the pleated shape.
How often should you clean cellular shades?
A weekly dusting is enough to prevent buildup for most homes; deeper cleaning with compressed air or spot treatment is only needed occasionally, when dust has settled deep into the cells or a visible stain appears.
How do you clean cellular shades without taking them down?
Dusting, compressed air, and spot cleaning can all be done with the shade still mounted — fully extend it first so the pleats sit flat, then work top to bottom. If you need more help, you can reach out to our team at support@uamblinds.com.
