The safest way to clean honeycomb blinds is to dust them regularly with a vacuum on low suction and a soft brush attachment, clear the inside of the cells with a hair dryer on the cool setting, and spot clean marks by dabbing — never rubbing — with a barely damp cloth. Honeycomb (cellular) shades are low-maintenance, but their pleated cell structure means dust settles inside the pleats and the fabric can crease permanently if it’s handled roughly. The steps below keep them looking crisp and working properly for years.
Quick Answer: How to Clean Honeycomb Blinds
- Lower the shade fully so the pleats open up and every surface is reachable.
- Vacuum both sides with a soft brush attachment on low suction, moving side to side along the pleats.
- Clear the cells with a hair dryer on the cool, low setting (or a can of compressed air) blown through one end of each cell.
- Spot clean marks by dabbing with a microfibre cloth dampened with lukewarm water and a drop of mild dish soap.
- Let it air dry fully lowered before raising the shade again.
What You Need
- A vacuum with a soft upholstery or dusting brush attachment (and adjustable suction, if you have it)
- A hair dryer with a cool setting, or a can of compressed air
- Two clean microfibre cloths
- Lukewarm water and a mild, clear dish soap
- A feather duster or lint roller for quick in-between touch-ups
Step 1: Routine Dusting (Every Few Weeks)
Lower the shade all the way so the pleats are extended. Hold the vacuum brush slightly away from the fabric rather than pressing it in, and work side to side in the direction of the pleats, top to bottom. Pressing hard or using a stiff brush flattens the honeycomb shape over time, which affects both how the shade looks and how well it insulates.
Do the room-facing side and then the window side. The window side usually collects more dust and, in winter, a little condensation residue near the bottom rail.
Step 2: Cleaning Inside the Cells
This is the step most people skip, and it’s where dust, small insects and debris collect. With the shade fully lowered, set a hair dryer to its cool, low setting and blow through the open end of each cell row; the debris comes out the other side. Hot air is not a good idea because it can soften the adhesive that holds the pleats together. A can of compressed air works too; keep it upright and use short bursts.
Step 3: Spot Cleaning Marks and Stains
Mix lukewarm water with a drop of mild, clear dish soap. Dampen a microfibre cloth until it’s barely damp (wring it out well) and dab the mark gently. Rubbing or scrubbing can distort the thin cell walls or leave a shiny patch on the fabric. Follow with a second cloth dampened with plain water to lift any soap, then let the area dry with the shade fully lowered.
If a stain doesn’t lift after a couple of gentle passes, stop there. Forcing it usually does more damage than the stain itself, especially on light-filtering fabrics where a water ring can show against the light.
How to Clean Honeycomb Blinds Without Taking Them Down
Everything above can be done with the shade in place, which is the approach we recommend for almost every home. Taking a honeycomb shade down means working with brackets and clips that are easy to bend, and many cordless systems need to be re-seated carefully to keep their tension. Leaving the shade mounted also avoids creasing the fabric while you move it. For most households, a regular dusting routine plus occasional spot cleaning is all that’s ever needed.
What Not to Do
- Don’t soak or submerge the shade (for example, in a bathtub) unless the manufacturer’s care instructions for your specific shade say it’s allowed. Water can weaken the adhesive, leave marks, and damage the headrail, and it should never be done with blackout-lined or motorized shades.
- Don’t use a steam cleaner; heat and moisture together can permanently collapse the cells.
- Avoid harsh cleaners such as bleach, ammonia or solvent-based products, which can discolour the fabric.
- Don’t press or crease the pleats while cleaning, and never raise the shade while the fabric is still damp.
Extra Care for Cordless and Motorized Honeycomb Shades
Cordless shades use an internal spring system that normally needs no maintenance; just lower and raise them by the bottom rail with even pressure rather than pulling from one corner. For motorized shades, keep moisture away from the headrail and motor entirely, and clean the fabric only with the dry methods (vacuum and cool air) plus careful spot cleaning. If a motorized shade starts to stall or move unevenly, that’s a mechanical issue rather than a cleaning one; see our guide to what to check when motorized blinds act up.
A Seasonal Note for GTA Homes
Homes across Mississauga, Toronto and the rest of the GTA with forced-air heating tend to see more dust near windows from November to March, when the furnace runs constantly. A quick dusting every two to three weeks in winter keeps it from building up inside the cells. Kitchens need a little more attention because cooking vapour can leave a film, while bathrooms benefit from good ventilation to keep humidity away from the fabric.
When Cleaning Isn’t the Fix
A shade that sags on one side, cells that stay flattened and won’t spring back, or a shade that won’t stay up are signs of a mechanical problem, not dirt. Our troubleshooting guide explains the most common causes: honeycomb blinds won’t close or won’t go up. If a shade is damaged beyond a simple fix, a replacement made to measure for your window is often the better long-term option.
Frequently Asked Questions
Can you wash honeycomb blinds in the bathtub?
Only if the manufacturer’s care instructions for that specific shade allow it. Many honeycomb shades are not designed to be submerged: water can weaken the pleat adhesive and damage the headrail. It should never be done with motorized or blackout-lined shades. Dry cleaning with a vacuum and cool air, plus careful spot cleaning, is the safer choice.
How often should honeycomb blinds be cleaned?
A light dusting every few weeks is enough for most rooms, a little more often in winter in homes with forced-air heating. Cleaning inside the cells two to three times a year keeps them clear of debris.
Can I use vinegar on honeycomb blinds?
We don’t recommend it. Mild dish soap diluted in lukewarm water is gentler on the fabric and less likely to leave a mark. Always test on a small, hidden area first.
Why are the cells on my honeycomb blind collapsing?
Cells usually flatten from pressure (pressing a brush or cloth into them), from heat or steam, or from moisture that softened the adhesive. Once the cell structure has collapsed, it generally can’t be restored by cleaning.
Do honeycomb blinds still insulate if they’re dusty?
Dust doesn’t stop them from insulating, but crushed or distorted cells do reduce the air pocket that makes honeycomb shades energy efficient. Learn more in our comparison of pleated vs. honeycomb shades for energy savings.
