How to Clean Cellular Shades

Cellular shades, also known as honeycomb shades, are a popular choice for their clean appearance and insulating design. Their distinctive honeycomb-shaped cells trap air, helping reduce heat transfer around windows.

But what happens when dust starts collecting on the fabric, fingerprints appear near the bottom rail, or a small bug finds its way inside one of those cells?

Cleaning cellular shades takes a little more care than wiping down traditional blinds. The fabric is often delicate, and the pleated honeycomb structure can lose its shape if it's scrubbed, squeezed, or exposed to too much moisture.

Fortunately, routine maintenance is usually straightforward. A microfiber duster or a vacuum with a soft brush attachment can handle much of the everyday buildup.

In this guide, we'll walk through how to clean cellular shades safely, remove loose debris from the honeycomb cells, deal with common household stains, and recognize when it's better to call a professional.

Take a look at cellular shades from the side, and you'll see rows of hollow, honeycomb-shaped cells. When the shade is lowered, these cells create air pockets that help slow heat transfer around the window.

Cellular shades come in different constructions, including single-cell and double-cell designs. You'll also find light-filtering and blackout fabrics, each designed for different lighting and privacy needs.

While many of these shades can be dusted in much the same way, their tolerance for water and cleaning products may vary. Some blackout fabrics, for example, contain special coatings or inner layers that require additional care.

If you're comparing styles, explore our Cellular Shades collection to see the different designs and options available.

There are three main reasons.

The fabric can be delicate. Aggressive scrubbing or abrasive tools may cause pilling, surface wear, or discoloration.

The cells can lose their shape. Strong vacuum suction or too much pressure may crush or distort the pleats.

Some materials are sensitive to moisture. Excess water can leave marks or affect adhesives, blackout linings, and certain hardware components.

A good rule of thumb is to start with dry cleaning methods. Only move on to spot cleaning if the shade's care instructions allow it.

You probably already have most of the tools you need at home.

Gather a microfiber duster, a vacuum with a soft brush attachment, clean microfiber cloths, and a dry towel. For approved spot cleaning, have a bowl of lukewarm water and a suitable mild detergent ready.

Avoid stiff brushes, rough sponges, and abrasive cleaning pads. They can damage the fabric even when you're only trying to remove a small mark.

If the manufacturer allows damp spot cleaning, mix a small amount of mild detergent into a bowl of lukewarm water.

A few options include:

• Mild soapy water: A little gentle soap diluted in water.
• Mild dish soap: Choose a gentle formula rather than a heavy-duty degreaser.
• Woolite detergent: A suitable gentle formula designed for delicate fabrics may be an option, provided the shade's care instructions allow it.

You only need a small amount. Using more detergent won't necessarily remove stains faster, and leftover soap can create marks of its own.

Never use bleach, ammonia, or harsh chemical cleaners on cellular shade fabric. These products may permanently damage the fibers, color, or protective coatings.

Before treating a visible stain, test the diluted solution on a small, inconspicuous area. Check for discoloration, water marks, or changes in the fabric.

If the manufacturer specifies dry cleaning only, skip the cleaning solution entirely.

For everyday dust, you may only need the first three steps. Spot cleaning is best reserved for stains that don't come off with dry methods—and only when the fabric's care instructions permit it.

Start by lowering the shade so the fabric is fully extended.

This makes it easier to see dust along the pleats and inspect the bottom rail, edges, and back of the shade.

Look for fingerprints, pet hair, water spots, and any insects or debris trapped inside the honeycomb cells.

For motorized shades, stop the motor and follow the manufacturer's instructions for disconnecting power when appropriate.

Use a clean microfiber duster, starting at the top and working your way down.

Follow the horizontal pleats with light strokes rather than rubbing repeatedly in one spot.

Try not to squeeze the cells or pull on the fabric edges.

If you dust regularly, this may be all the cleaning your shades need.

When dust has had time to build up, a vacuum with a soft brush attachment can help.

Here's how to do it:

1. Set the vacuum to its lowest suction level.
2. Attach a soft brush suitable for delicate fabric.
3. Work slowly from the top of the shade downward, following the pleats.
4. Keep the nozzle from pulling or catching the fabric.
5. Clean both sides as needed.

If the fabric starts lifting toward the nozzle or the pleats become distorted, stop and switch back to a duster.

For many households, a light dusting every week or two is easier than dealing with months of buildup.

If a fingerprint or small stain remains, check the manufacturer's cleaning instructions before using water.

When damp spot cleaning is permitted:

1. Mix a small amount of mild soap, gentle dish detergent, or an approved Woolite formula with lukewarm water.
2. Dip a clean microfiber cloth into the solution.
3. Wring it out thoroughly. The cloth should be barely damp, not wet.
4. Test a hidden area first.
5. Gently blot the stain, working from the outside toward the center.
6. Use a second clean, lightly dampened cloth to remove detergent residue.
7. Blot with a dry towel to absorb remaining moisture.

Don't spray the solution directly onto the shade, and don't scrub back and forth.

If the stain doesn't improve, avoid adding more detergent or increasing pressure. Persistent stains may need professional attention.

After spot cleaning, leave the shade extended in a well-ventilated room until the fabric is completely dry.

Avoid heated hair dryers, irons, or other heat sources.

Try not to raise and lower the shade repeatedly while the fabric is damp, since folding wet pleats can put unnecessary pressure on them.

Once dry, operate the shade normally according to its care instructions.

One of the more frustrating things about honeycomb shades is that small insects and bits of debris can sometimes get inside the cells.

You might not notice them at first. But on light-colored, light-filtering shades, a dark speck inside a cell can become especially noticeable when sunlight shines through.

Use Gentle, Cool Air

If the cell has accessible openings that allow air to pass through, a gentle stream of cool air may help.

Lower the shade completely and locate the cell containing the debris.

Set your hair dryer to its lowest cool-air setting. Hold it a safe distance from the fabric and direct the airflow along the cell.

If the debris is loose and the air can pass through, it may come out the opposite end.

Use cool air only. Never press the hair dryer against the fabric or use a heated setting.

Be Careful with Compressed Air

A low-pressure air tool may also help loosen dust inside accessible cells.

Be careful with canned compressed air. Strong airflow can damage delicate material, and improper use may expose the fabric to liquid propellant.

Follow the tool's instructions and avoid using it if the cells are particularly fragile or difficult to access.

Avoid Sharp Objects

Resist the temptation to push it out with a needle, toothpick, or wire.

The thin walls of the honeycomb cells can be punctured easily, leaving permanent holes.

If gentle airflow doesn't work, contact the manufacturer or a professional window treatment cleaner for advice.

Not every mark on cellular shades needs the same treatment. Dust and pollen are usually easy to remove, while grease and liquid stains can be more stubborn.

Dust and Pollen

For ordinary dust and pollen, start with a microfiber duster or a vacuum on low suction.

There's usually no need for water or detergent.

If you live near a busy road or keep windows open during pollen season, you may need to dust more often.

Fingerprints

Fingerprints often appear near the bottom of shades that are raised and lowered by hand.

Try gently blotting the area with a clean, dry cloth first.

If the mark remains and the fabric allows damp cleaning, use a small amount of the mild cleaning solution described earlier.

To prevent new marks, operate cordless shades using their designated handle or operating area whenever possible.

Kitchen Grease

Cellular shades installed in kitchens may collect tiny airborne grease particles over time.

Unlike ordinary dust, grease can cling to fabric fibers and may not come off with vacuuming alone.

Remove loose dust first. If the fabric allows damp spot cleaning, test a small hidden area before gently treating the grease with diluted mild dish soap.

Avoid heavy-duty degreasers, alcohol, bleach, ammonia, or soaking the fabric. Deeply embedded grease may not respond to home cleaning.

Drink Spills

If a drink splashes onto your shade, act quickly.

Use a clean, absorbent cloth to blot up as much liquid as possible. Don't rub the stain outward, which can spread it.

If the material allows damp spot cleaning, follow the manufacturer's directions and use only a small amount of cleaning solution.

Stains from sugary or heavily colored drinks can be harder to remove, especially if liquid has entered the honeycomb cells.

Pet Hair

Pet hair can cling to fabric, particularly near windows where pets like to sit.

A soft vacuum brush on low suction is usually the best place to start.

Be cautious with sticky lint rollers. Strong adhesive may pull on the fabric fibers.

Musty Smells and Suspicious Spots

If your shades develop a musty smell or suspicious spots, check the surrounding window for condensation, leaks, or poor ventilation.

If the area is simply damp, improve airflow and keep the shade dry.

If visible mold has developed, don't attempt to remove it with bleach, ammonia, or large amounts of cleaning solution.

For extensive contamination, consult a qualified professional and consider whether replacement is necessary.

Motorized cellular shades follow many of the same fabric-care rules as manual shades. The main difference is the presence of electrical and mechanical components.

Make sure the shade isn't moving. Follow the manufacturer's instructions for disconnecting power when appropriate.

Never clean or handle the fabric while the motor is operating.

Use a microfiber duster or a vacuum with a soft brush on low suction.

Avoid pulling on the fabric or putting pressure on the lifting mechanism.

Never spray water or cleaning solution onto the headrail, motor, power connections, or controls.

If the shade needs to be removed or requires more extensive cleaning, consult the manufacturer or a qualified professional first.

You may have seen tutorials showing cellular shades being washed in a bathtub.

That doesn't mean the method is safe for every product.

Different manufacturers use different fabrics, adhesives, blackout linings, and hardware. Some materials tolerate limited moisture, while others can lose their shape or separate when soaked.

Unless the manufacturer specifically approves full washing or immersion, don't soak cellular shades.

Here's why several common cleaning methods can be risky:

Soaking exposes the whole shade to moisture; steam adds heat; and scrubbing puts pressure on the fabric and pleats. These can affect the materials, adhesives, or shape of the shade.

If your particular shades are labeled washable, follow their specific instructions rather than relying on a general cleaning tutorial.

Usually, no.

Most routine tasks can be done while the shades are installed, including dusting, low-suction vacuuming, removing some loose debris from the cells, and spot cleaning when permitted.

Taking down traditionally mounted shades every time they get dusty creates extra work and may put unnecessary wear on the brackets or headrail.

Some no-drill cellular shades have mounting systems that make installation and removal more convenient. However, the exact process depends on the product, and a no-drill design doesn't automatically mean the shade should be removed for routine cleaning.

If you're looking for window coverings that don't require drilling into the window frame, explore our No-Drill Shades collection, which includes options for different window setups.

Most everyday dust doesn't require professional cleaning. But some problems are better left to someone familiar with delicate window treatments.

Large or stubborn stains: Years of cooking grease, smoke residue, or stains that have penetrated the fabric may be difficult to treat safely at home.

Debris trapped deep inside the cells: If gentle airflow doesn't work, stronger tools may do more harm than good.

Visible mold: A professional can help assess whether cleaning is practical or replacement is the safer option.

Damaged or misshapen cells: Collapsed pleats, separating fabric, or lifting problems may indicate structural damage rather than a cleaning issue.

There's no single schedule that works for every home.

Shades in a rarely used guest room may stay relatively clean for weeks. Kitchen windows, busy living areas, and rooms where pets spend time can collect dust and hair much faster.

Use this as a general maintenance guide:

Start with light dusting every one to two weeks, vacuum when dust builds up, and address spills promptly using only methods permitted by the manufacturer. Adjust the routine for kitchens, pets, pollen, and busy rooms.

These are practical guidelines, not mandatory cleaning intervals.

Regularly removing loose dust and dealing with small marks promptly can help prevent the need for more intensive cleaning later.

A few simple habits can make future cleaning much easier.

When operating cordless cellular shades, use the designated handle or operating area whenever possible.

This helps keep skin oils and fingerprints off the fabric.

Dust collecting on window sills and frames can eventually settle on the shades.

When you dust your window coverings, take a moment to wipe down the surrounding surfaces too.

Be careful when moving furniture, cleaning windows, or placing decorations near the shades.

Furniture corners, sharp tools, and pet claws can catch or puncture the honeycomb material.

What Is the Best Way to Clean Cellular Shades?

For routine maintenance, use a microfiber duster or a vacuum with a soft brush attachment on the lowest suction setting. Only use a mild cleaning solution for spot cleaning if the manufacturer permits it.

Can You Wash Cellular Shades with Water?

Some cellular shades allow light damp spot cleaning, but that doesn't mean they can be fully washed. Check the manufacturer's instructions before using water, and avoid soaking unless specifically approved.

How Do You Remove Bugs from Honeycomb Shades?

If the cells have accessible openings, try using a hair dryer on a low, cool setting to blow out loose insects. Don't insert sharp objects or use hot air.

Can You Vacuum Cellular Shades?

Yes, if the manufacturer's care instructions allow it. Use a soft brush attachment and low suction to avoid pulling on the fabric or distorting the pleats.

Start with dry dusting or gentle vacuuming. Some blackout fabrics have coatings or inner layers that may be sensitive to moisture, so check the care instructions before spot cleaning.

If you're comparing room-darkening options, take a look at our Blackout Cellular Shades collection.

Can You Steam Clean Cellular Shades?

Steam cleaning isn't recommended as a general method. Heat and moisture can affect fabric, adhesives, and pleat shape. Only use it if the manufacturer specifically approves it.

How Often Should Cellular Shades Be Dusted?

Light dusting every one to two weeks works as a starting point for many households. Vacuum as needed, especially in kitchens, high-traffic rooms, or homes with pets.

Can Stains Be Removed from Cellular Shades?

Some light stains can be removed with careful spot cleaning. If the fabric permits damp cleaning, a small amount of mild soapy water, diluted gentle dish soap, or an approved Woolite solution may help. Persistent stains may need professional treatment.

How Do You Clean Motorized Cellular Shades Safely?

Stop the motor and follow the manufacturer's safety instructions. Dust the fabric gently, and keep all liquids away from the motor, headrail, and electrical connections.

On lighter fabrics, debris inside a honeycomb cell may be more noticeable when sunlight passes through. If you're comparing how different shades soften natural light, explore our Light Filtering Cellular Shades collection.
