To clean most blinds, close the slats, dust them top to bottom with a microfiber cloth or a vacuum brush attachment, then flip them the other way and repeat — a quick weekly pass keeps them from ever needing more. For a deeper clean, wipe each slat with a barely-damp cloth, but only on materials that tolerate moisture: faux wood, aluminum and vinyl are fine wet; real wood and fabric shades are not. The right method depends entirely on what your blinds are made of, so here’s the honest, material-by-material breakdown.
How do you clean blinds?
Close the blinds so the slats form a flat surface, then dust from the top down using a microfiber cloth, a sock over your hand, or a vacuum on low with a soft brush. Tilt the slats the opposite direction and dust again to catch both sides. For built-up grime, wipe faux wood, aluminum or vinyl slats with a cloth dampened in warm water and a drop of dish soap — but keep water off real wood blinds and fabric shades, which should only be dry-dusted or spot-cleaned. Finish by drying any damp slats so they don’t spot.
The weekly once-over that prevents real cleaning
Ninety percent of blind cleaning is just not letting dust build up in the first place. Once a week, run a microfiber cloth, a clean sock on your hand, or your vacuum’s soft-brush attachment along the closed slats — top to bottom, then flip and repeat. It takes under two minutes per window and means you almost never have to do the wet, slat-by-slat deep clean.
- Close the slats fully so they overlap into one flat panel.
- Dust downward (upward flicks dust back onto clean slats).
- Reverse the tilt and dust the other side.
- For cords and the headrail, a quick pass with the vacuum brush finishes the job.
That’s the whole routine for most homes. Everything below is for when a slat actually needs washing — and where people go wrong is treating every blind the same. They aren’t.
The blind-cleaning cheat sheet, by material
How to clean wood blinds
Real wood is the one everyone gets wrong. Those warm basswood slats are beautiful, but wood is porous — standing water swells it, lifts the finish, and leaves cloudy marks that don’t buff out. So wood blinds get dusted, not washed: a dry microfiber cloth or a vacuum brush for the weekly pass, and for stubborn spots, a cloth dampened with a tiny bit of water or wood cleaner, wrung out until it’s almost dry, wiping one slat at a time and drying immediately behind it.
A drop of wood-safe furniture cleaner once or twice a year keeps the finish from drying out. Skip the all-purpose sprays — the ammonia in many of them dulls a wood finish over time.
How to clean faux wood blinds
This is where faux earns its keep. Faux wood and composite blinds are made to shrug off moisture, which is exactly why we put them in kitchens and bathrooms instead of real wood. That means you can actually wash them: wipe each slat with a cloth dipped in warm water and a drop of dish soap, and for greasy kitchen film, a 50/50 water-and-white-vinegar mix cuts it fast.
For blinds that are truly caked, faux wood is light and water-safe enough to take down and rinse in the tub or with a hose — but read the caution in the “never do” section first, because even here there’s a right and wrong way. Dry the slats before you re-hang so water doesn’t sit in the route holes.
How to clean aluminum & mini blinds
Aluminum blinds are non-porous, so water is no problem — the thing to protect here is the shape of the slat, not the finish. Thin metal slats crease if you press too hard, and a bent slat never sits right again. Dust or vacuum weekly; for a deeper clean, wipe with a damp cloth, supporting the slat from behind with your other hand so you’re not folding it as you go.
An old cotton glove or sock on your hand lets you pinch each slat and clean both sides in one pass. Wipe along the length of the slat, not across it.
How to clean cellular, pleated & fabric shades
Fabric window treatments follow completely different rules — there are no slats to wipe, and the fabric is the finish and the function at once. For cellular shades, pleated shades and Roman shades, the weekly move is a vacuum on the lowest suction with a soft brush attachment, run gently down the fabric. For the honeycomb pockets on cellular shades, a quick shot from a hair dryer on the cool setting blows dust out of the cells.
For spots, dab — never rub — with a cloth and a little mild soapy water, then blot dry and let the shade hang fully open until completely dry. Rubbing a fabric shade pills and distorts it, and soaking can leave a permanent tide line. If a fabric or woven shade is genuinely stained, that’s the moment to ask about professional cleaning rather than risk it.
What to never do to your blinds
A few shortcuts do more harm than a year of dust:
- Don’t soak real wood or fabric. Water is the enemy of both — warping for wood, tide lines for fabric.
- Be careful with the “bathtub method.” It’s only for faux wood, vinyl or aluminum, never wood or fabric — and never for blinds with a built-in motor. Dry them fully before re-hanging.
- Skip abrasive pads and harsh chemicals. Scouring scratches slats and strips finishes; ammonia dulls them.
- Never get water near motorized blinds. Motorized and smart shades get dry-dusting only — keep moisture away from the motor and battery housing.
When it’s time to replace instead of clean
Sometimes the honest answer is that the blinds are done. Yellowed slats, frayed cords, bent vanes that won’t sit straight, or fabric that’s stained through don’t come back with cleaning — and a tired set of blinds ages a whole room. If yours are past saving, it can cost less than you’d think to start fresh with cordless or motorized options that are far easier to keep clean.

Frequently asked questions
How often should you clean blinds?
Dust blinds once a week with a microfiber cloth or vacuum brush to prevent buildup, and do a deeper clean a few times a year or whenever film and grime become visible. Kitchens and bathrooms usually need deeper cleaning more often because of grease and humidity.
Can you clean blinds with water?
It depends on the material. Faux wood, vinyl and aluminum blinds can be safely cleaned with warm, soapy water, but real wood blinds and fabric shades should be kept dry and only dusted or spot-cleaned, since water warps wood and stains fabric.
How do you clean blinds without taking them down?
Close the slats to form a flat surface and dust from top to bottom with a microfiber cloth, a sock over your hand, or a vacuum brush attachment, then reverse the tilt and repeat for the other side. For grime on faux wood or aluminum slats, wipe each one in place with a barely-damp cloth.
Can you wash faux wood blinds in the bathtub?
Yes, faux wood, vinyl and aluminum blinds can be soaked and rinsed in a tub because they resist moisture, but real wood blinds, fabric shades and any motorized blinds should never be submerged. Dry the slats completely before re-hanging so water does not sit in the cord holes.
What is the fastest way to clean blinds?
The fastest method is to close the slats and run a vacuum with a soft brush attachment or a microfiber dusting tool down both sides, which takes under two minutes per window. Doing this weekly prevents the buildup that would otherwise require slow, slat-by-slat wet cleaning.
