Cellular shades (also called honeycomb shades) are super popular for good reason. They look great, help with energy bills, and give you awesome light control. But here's the thing—those unique honeycomb pockets that make them so special can also trap dust, dirt, and even the occasional bug. Don't worry though! Cleaning these shades doesn't have to be a nightmare. We're here to walk you through everything you need to know about keeping your cellular shades looking fresh and working perfectly.
What Makes Cellular Shades Special?
Before we jump into cleaning, let's talk about what makes these window treatments tick. Cellular shades have a three-dimensional honeycomb structure that traps air in small pockets. From the side, they literally look like a bee's honeycomb. This design creates insulation that protects your home from heat, cold, and even sound. That's why so many homeowners love them—they're both functional and stylish.
The thing is, this same cellular design can collect dust and debris inside those tiny pockets. Regular cleaning keeps your shades looking good and helps them last longer. Plus, when you remove dirt regularly, you're also getting rid of mold and fungus spores that could stain your shades when they get wet. So keeping up with cleaning is actually a smart move for protecting your investment.
Supplies You'll Need for Cleaning
The good news? You probably already have most of what you need at home. Here's what to grab:
Vacuum cleaner with a soft brush attachment - This is your best friend for regular maintenance
Microfiber cloth or feather duster - Perfect for light weekly dusting
Can of compressed air - Great for blowing out bugs and debris from inside the cells
Mild detergent (like dish soap) - For spot cleaning stains
Soft, clean cloths or sponges - For applying cleaning solutions
Lukewarm water - Never use hot water, which can damage the glue
Lint roller - Helpful if you have pets

Regular Dusting (Weekly Maintenance)
The easiest way to keep your cellular shades clean is to dust them regularly—we're talking once a week or every two weeks. This simple habit prevents dust from building up and turning into stubborn stains later.
Here's how to do it: Fully extend your shades so you can see the entire surface. Grab a feather duster or microfiber cloth and lightly wipe each cell in one direction, working from top to bottom. Don't rub back and forth too hard, as this can mess with the pleats or cause the fabric to pill. Just gentle sweeps will do the trick.
If you're dealing with pet hair (we've all been there), a lint roller works wonders. Pull down the bottom of the shade gently to tighten the fabric, then run the lint roller across the surface. No pet hair can resist this treatment. This weekly routine takes maybe five minutes and saves you from major cleaning headaches down the road.
Vacuuming Your Cellular Shades
Once a month, give your shades a more thorough cleaning with your vacuum. This removes dust that's settled deeper into the fabric and keeps your shades looking like new.
Grab your vacuum and attach the hose brush attachment—this is super important because vacuuming without the brush can crumple and deform the fabric. Set your vacuum to a low suction setting. Then, swipe across the cell fabric in horizontal strokes, following the direction of the pleats. Work from top to bottom, covering both sides of the shade.
The brush attachment gently loosens dust and dirt while preventing the fabric from getting sucked up and wrinkled. If you notice stubborn dust spots that won't budge, you can carefully go over them again with a lint roller. Just remember to always work with the pleats, not against them.
How to Remove Bugs from Inside the Cells
Okay, let's address the elephant in the room—or should we say, the bug in the cell. Dead bugs, dust, and debris can get trapped inside those honeycomb pockets, and seeing their silhouettes through translucent shades is not a good look. But don't panic! This is actually super easy to fix.
First, lay down a drop cloth or some newspaper underneath your cellular shades to catch whatever falls out. Then grab a can of compressed air (the kind you use to clean your keyboard). Put the straw into the opening of each cell and spray. The forced air will blow out dust, dirt, and any "departed arachnids" that made their way inside.
You might need to spray from both ends of each cell to make sure you've cleared everything out. If you don't have compressed air, a hair dryer on the coolest, lowest setting can work too. Just be careful—excessive heat can damage the adhesive that holds the fabric together and might warp your shades.
Spot Cleaning Stains
Life happens. Coffee spills, kids' sticky fingers, random splatters—stains are inevitable. The key is to tackle them quickly and gently.
Always try dusting and vacuuming first before you bring water into the picture. If that doesn't work, here's what to do: Mix lukewarm water with a few drops of mild detergent like dish soap. Dampen a soft, lint-free cloth with this solution and wring it out well—the cloth should be damp, not dripping wet.
Gently blot the stained area. Don't scrub or rub hard, as this can cause pilling or damage to the delicate fabric. Work from the outside edge of the stain toward the center to keep it from spreading. Keep blotting until the stain starts to fade. Then, take another clean cloth dampened with plain water and blot the area to rinse away soap residue. Finally, blot dry with a clean, dry cloth.
Important warning: Never submerge your shades in water or get them overly wet. The fabric can lose its shape, and metal components might rust or deteriorate. Once your shades are mostly dry, leave them raised for a few hours to help re-train the pleats.
Deep Cleaning Methods
Sometimes regular maintenance just isn't enough. If your shades are looking really grimy or stained, you have a couple of options. But first, check your manufacturer's instructions—some fabrics don't handle deep cleaning well, and you don't want to void your warranty.
The Bathtub Method (Use with Caution)
Some people swear by the bathtub method, but it comes with risks. Many manufacturers, including major brands, actually recommend against soaking cellular shades completely. Soaking can damage the fabric, cause the shades to lose their shape, and break down the adhesives.
If your manufacturer says it's okay and you decide to try it, here's how: Fill your bathtub with just a few inches of lukewarm water and add a tiny bit of mild detergent. Remove your shades from the window and gently submerge them. Let them soak for just 3-5 minutes—no longer, or you risk permanent damage. Gently swish them in the water, then drain and rinse with clean water. Lay them flat on clean towels to air dry, or rehang them fully extended. Never wring or twist the fabric.
Professional Ultrasonic Cleaning
For heavily soiled shades or if you're nervous about DIY deep cleaning, professional ultrasonic cleaning is your best bet. With this method, a professional service uses high-frequency sound waves to create millions of tiny bubbles that gently remove dirt, dust, and bacteria without damaging the fabric.
The pro will come to your home with a large tank of cleaning solution, dip your shades in, and let the sound waves do their magic. It's safe, effective, and won't void your warranty. Professional cleaning costs vary, but it's worth considering if your shades are expensive or delicate.
What NOT to Do When Cleaning Cellular Shades
Let's talk about the biggest mistakes people make when cleaning these shades:
Don't use harsh chemicals - Bleach, ammonia, spot removers, and even products like Woolite can harm your cellular shades and cause discoloration
Don't scrub the fabric - This causes pilling, damage, and can remove the protective finish
Don't use hot water - Heat can weaken the glue holding the cells together and warp the fabric
Don't soak blackout shades - Blackout fabrics are especially prone to water spotting and delamination
Don't use magic erasers - They're actually a fine abrasive and can create permanent dull spots or holes
Don't dry them in direct sunlight - This can cause fading and weaken the fabric
Don't vacuum without the brush attachment - High suction without protection will deform your shades
Don't fold shades while they're damp - This causes permanent creases

Tips for Different Types of Cellular Shades
Not all cellular shades are created equal. Here are some specific tips:
Single Cell vs. Double Cell: Both types can be cleaned the same way—monthly dusting and spot cleaning with mild soap and water. Just use extra caution with double-cell shades not to crush or stretch the fabric since there are more layers.
Blackout Cellular Shades: These need special care because the blackout backing is prone to water spotting. Use minimal moisture, test any cleaning method on a hidden area first, and blot liquids immediately. Air drying is crucial—make sure they're completely dry before raising them.
Light-Filtering Shades: These can sometimes handle a bit more moisture than blackout fabrics, but always check manufacturer guidelines first. The bathtub method (if recommended) is more likely to be safe for these than for blackout options.
Motorized Shades: If you have a motorized headrail, it must be removed before any wet cleaning. Never get the motor or headrail components wet.
Keeping Your Shades Clean Longer
A few simple habits can reduce how often you need to deep clean:
Close your windows during dusty or windy days
Use air purifiers to reduce airborne particles
Clean window frames and sills regularly so dust doesn't transfer to shades
Handle shades gently when raising and lowering them
Keep cords and wands clean by wiping them with a damp cloth
If you live near the coast, dust more frequently due to salt air particles
When to Call a Professional
Sometimes DIY just isn't enough. Consider professional cleaning if:
Your shades haven't been cleaned in years and are heavily soiled
You have delicate or expensive designer fabrics
There are deep-set stains that won't respond to gentle spot cleaning
Your shades have special finishes or treatments
You're worried about damaging them or voiding the warranty
You don't have time for DIY cleaning
Professional blind cleaning typically costs between $140-$350 depending on how many shades you have and the cleaning method used. For cellular shades specifically, expect around $7.50-$9 per square foot. That's way cheaper than replacing damaged shades!
FAQs
Can you wash cellular shades in the washing machine?
No, you should never put cellular shades in a washing machine. The agitation and water saturation will damage the delicate honeycomb structure, warp the fabric, and destroy the shape of your shades. Stick to gentle hand cleaning methods like vacuuming and spot cleaning.
How often should you clean cellular shades?
Dust your cellular shades weekly or every two weeks with a feather duster or microfiber cloth. Vacuum them monthly with a soft brush attachment. Spot clean stains as soon as they happen. Deep cleaning should only be done once a year if needed, preferably by professionals.
What happens if my cellular shades get too wet?
If your shades get overly wet, blot away as much moisture as possible with a clean, dry towel. Don't twist or wring the fabric. Then fully extend the shades and let them air dry completely to help the pleats keep their shape. Avoid folding them while damp.
Can I use Windex or other spray cleaners on cellular shades?
No, avoid spray cleaners, Windex, bleach, or harsh chemicals on cellular shades. These can damage the fabric, cause discoloration, and break down the adhesive holding the cells together. Stick to mild dish soap diluted in lukewarm water for spot cleaning.
Why do my cellular shades look dingy even after cleaning?
If your shades still look dingy after regular cleaning, it could be from years of dust buildup, exposure to smoke or cooking grease, or sun damage. Try professional ultrasonic cleaning first. If that doesn't work, it might be time to replace them with fresh new shades.
