How to Clean Blinds: A Room-by-Room Guide for Every Blind Type
Blinds sit right in the path of dust, cooking grease, and damp air, so they get dirty faster than almost anything else in a room. Learning how to clean blinds properly takes less time than most people expect — as long as you match the method to the material. What revives aluminium Venetians can ruin real wood, and a soaking bath that restores vinyl can destroy a cellular shade.
This guide covers Venetian, wood, faux-wood, vertical, roller, cellular, and fabric or Roman blinds, with exact cleaning solutions, tools, and drying times, plus room-by-room advice, stain removal, cord safety, and the mistakes to avoid.
Key Takeaways
- Dust weekly; deep clean every three to six months, more often in kitchens and bathrooms.
- Never soak real wood blinds — wipe with a barely damp cloth and dry each slat immediately.
- Everyday solution: 1 litre warm water with 1 teaspoon mild dish soap; add vinegar only on vinyl, aluminium, and faux wood.
- Always clean top to bottom, so dust falls onto slats you have not cleaned yet.
- Check cords and cleats every clean, and keep cords away from children and pets.
Before You Start: Tools and Cleaning Solutions
You need a microfibre cloth, a second dry cloth, a soft duster or old sock, a vacuum with a brush attachment, a bowl, mild dish soap, and white vinegar for hard surfaces only. For a deep clean, add a bathtub or large basin, a soft sponge, an old toothbrush for brackets, and a towel for drying.
The all-purpose solution is 1 litre of warm water mixed with 1 teaspoon of mild dish soap. For greasy vinyl, aluminium, or faux-wood slats, add 60 ml of white vinegar to the same litre. Never use vinegar or bleach on real wood, or solvents on fabric; test on a hidden slat first. Start with the blinds closed flat, dust top to bottom, then flip the slats and repeat. A weekly dust takes about 5 minutes per window; a deep clean takes 20 to 30 minutes.
How Often Should You Clean Blinds?
Light dusting once a week stops dust bonding to the surface, when it becomes far harder to remove. A full wipe-down every three months suits living rooms and bedrooms, while kitchens need a monthly wipe because cooking oil traps dust on slats. Bathrooms also benefit from a monthly clean, since humidity encourages mildew. Allergy sufferers should vacuum weekly and deep clean every two months. If you are refreshing the whole house, a deep cleaning checklist helps you fit blinds in the right order.
Venetian, Wood, and Faux-Wood Blinds
Aluminium and vinyl Venetians are the most forgiving. Close them flat, dust both sides, then wipe each slat with a cloth dampened in the dish-soap solution. For heavy grime, remove the blind, soak it in a bathtub of warm water with 60 ml of dish soap and 120 ml of white vinegar for 20 to 30 minutes, scrub gently, rinse, and hang in the shade until completely dry — usually 1 to 2 hours. Never use hot water on vinyl, which can warp.
Real wood needs a gentler touch. Never soak, steam, or leave wood blinds wet: moisture swells the wood, warps slats, and lifts the finish. Dust with a dry cloth, then wipe each slat with a cloth wrung out until barely damp, using plain water or the dish-soap solution, never vinegar. Dry each slat immediately with a second cloth. For sticky marks, dab a tiny amount of wood cleaner onto the cloth, never directly onto the slat. Faux wood, made from PVC or composite, can be treated like vinyl — damp-wipe freely or soak in the tub, then dry for 1 to 2 hours.
Vertical Blinds
Vertical blinds are easy to clean in place. Vacuum each vane top to bottom with the brush attachment, front and back. For vinyl or PVC vanes, wipe downward with a cloth dampened in the dish-soap solution, wipe again with a clean damp cloth, and let them air-dry for about 30 minutes. Fabric vanes need a lighter hand: vacuum first, then spot-clean with a cloth dampened in water and a drop of dish soap, blotting rather than rubbing so you do not fray the weave.
For a deep clean, unclip vinyl vanes one at a time — photograph the order first if they are patterned — soak them flat in warm soapy water for 20 minutes, rinse, and hang them back on the track to dry for 1 to 2 hours. Fabric vanes should not be machine-washed unless the label allows it. While the vanes are off, wipe the headrail and clear dust from the runners, which makes vertical blinds stick.
Roller Blinds
Roller blinds follow one rule: never roll a wet blind back up. Pull it fully down and vacuum both sides with the brush attachment. For vinyl rollers, wipe with the dish-soap solution, rinse with a clean damp cloth, and leave fully extended for 30 to 60 minutes until dry. For fabric rollers, spot-clean stains with a sponge dampened in 250 ml of warm water mixed with half a teaspoon of dish soap, blotting from the outside of the stain inward.
Grease spots respond to a paste of 1 tablespoon of bicarbonate of soda with a few drops of water, left for 15 minutes, then wiped away. Mildew on a bathroom roller needs a dab of 1 part white vinegar to 4 parts water, left for 10 minutes, wiped clean, and dried fully extended with the window open. Repeated soaking can shrink fabric, so heavily stained fabric rollers may need professional cleaning.
Cellular and Honeycomb Blinds
Cellular blinds trap air in hexagonal pockets, making them excellent insulators and the trickiest blinds to clean. Keep them as dry as possible. Vacuum weekly with the brush attachment on the lowest suction setting, running it gently down each pleat — high suction can crush the cells. For light marks, spot-clean with a cloth barely dampened in water and a drop of dish soap, blotting the pleat and then blotting dry. Never immerse a cellular blind, never steam it, and never scrub across the pleats, which can tear the fabric and collapse the honeycomb.
For dust inside the cells, use a hair dryer on the cool, low setting, blowing top to bottom, or a can of compressed air held at least 15 cm away. Spot-cleaned areas usually dry in 30 minutes, but leave the blind fully lowered until it feels completely dry — raising a damp cellular blind traps moisture inside the cells and invites mildew.
Fabric and Roman Blinds
Roman blinds fold into soft pleats that collect dust where it is hardest to reach. Lower the blind fully, vacuum both sides, and pay special attention to the fold lines. Spot-clean with a cloth dampened in the dish-soap solution, blotting never rubbing, and test on a hidden corner first because some dyes bleed. Many Roman blinds are dry-clean only; if the label allows hand-washing, remove the blind, take out battens or dowels, soak in cool water with gentle detergent for 20 minutes, rinse, and dry flat or hanging — never tumble-dry — for 4 to 6 hours.
Sheer and linen-look Romans fade in strong sun, so clean them in the shade and avoid bleach, even on white fabrics, which can yellow. Raising and lowering the blind after vacuuming shakes dust from the folds. Note that tile cleaners differ from fabric care — see how to clean grout so you do not splash tile cleaner onto a fabric blind.
Room by Room: Where Blinds Get Dirty Differently
The living room is mostly a dust story: sunlight bakes a thin layer onto slats, so a weekly dust and quarterly wipe suffice, and clean slats reflect noticeably more light. Bedrooms are an allergy story: vacuum weekly, wash bedding the same day, and open the window for 20 minutes after cleaning to clear airborne dust. Kitchens are a grease story: wipe monthly with the vinegar and dish-soap solution, and clean range-hood filters the same day. Bathrooms are a moisture story: wipe the headrail and bottom rail monthly, leave the blind raised or the window cracked after showers, and treat any black mildew spot early before it spreads into fabric.
Stain, Grease, and Smell Removal
Grease lifts with the dish-soap solution left on the mark for 5 minutes, or with the bicarbonate paste above. Nicotine yellowing on white vinyl responds to a 30-minute soak in warm water with 120 ml of white vinegar per litre; do not use bleach, which makes vinyl brittle. Water marks on wood should be dried immediately, then treated with a tiny amount of wood oil rubbed along the grain. For smells, vacuum thoroughly and air the blind; musty fabric can be misted with 250 ml of water and 1 tablespoon of white vinegar, then left fully extended until dry. Vents need their own method — see how to clean a dryer vent for the lint and airflow side of a whole-house clean.
What NOT to Do, and Cord Safety
Do not soak real wood blinds, steam any blind unless the manufacturer allows it, or use abrasive scouring pads on any slat — they leave fine scratches that trap dirt forever. Spray cleaner onto the cloth, never directly onto blinds, so liquid does not pool in the headrail and damage the mechanism. Do not close a damp blind, roll up a wet roller, or raise a damp cellular shade, and never rehang blinds before they are fully dry. Do not use bleach on coloured fabric or wood, and never mix bleach with vinegar.
Cord safety deserves a check every time you clean. Loop cords and bead chains are a strangulation hazard for young children and pets. Keep cots and climbable furniture away from windows with corded blinds, fit a cleat to hold cords taut against the wall, and replace loop cords with cordless wands where possible. Inspect cords for fraying while cleaning and replace a frayed cord before it snaps. In homes with small children, cordless or motorised blinds are safest.
Slip a microfibre sock over your hand, dampen it, and pinch each slat — both sides cleaned in one pass.
On wood blinds, follow every damp wipe with a dry cloth on the same slat.
Dust falls downward, so start at the headrail and finish at the bottom rail.
Blinds dry faster and smell fresher with the window open and sun out.

Frequently Asked Questions
Can I put blinds in the washing machine?
No, not as a general rule. Vinyl and aluminium Venetians can be bathed by hand, but machine washing bends slats and damages headrails. Fabric Romans should only be washed if the label allows it, and cellular blinds should never be immersed.
What is the best homemade solution for cleaning blinds?
For most blinds, 1 litre of warm water with 1 teaspoon of mild dish soap is safest. Add 60 ml of white vinegar per litre for greasy vinyl, aluminium, or faux-wood slats, but skip vinegar on real wood and delicate fabrics.
How do I clean blinds without taking them down?
Close the slats flat, dust or vacuum both sides top to bottom, then wipe each slat or vane with a damp microfibre cloth. Vertical, roller, and cellular blinds are all designed to be cleaned in place this way.
How long do blinds take to dry after washing?
Wiped blinds dry in 30 to 60 minutes. Bathed vinyl or faux-wood blinds need 1 to 2 hours in the shade, and hand-washed Romans need 4 to 6 hours. Never rehang or roll up a blind until it feels completely dry.
How do I remove grease from kitchen blinds?
Wipe with the dish-soap and vinegar solution, leaving it on the grease for 5 minutes before wiping clean. For stubborn spots, apply a bicarbonate of soda paste for 15 minutes, then wipe away and dry the slat.
Are steam cleaners safe for blinds?
Steam is risky for most blinds: it warps real wood, can shrink fabric, and may damage roller and cellular coatings. Stick to vacuuming, damp wiping, and hand-bathing vinyl and aluminium, unless the manufacturer explicitly recommends steam.
Start With One Window Today
You do not need to clean every blind in the house this weekend. Pick the window you look through most, dust it top to bottom, wipe it with the dish-soap solution, and let it dry in open air. Once you see how much brighter that one window looks, the rest will feel easy. Keep a weekly five-minute dusting habit, a quarterly wipe-down, and a monthly kitchen check, and your blinds will stay clean and last longer.
