Vertical blinds are a staple in Greek apartments, holiday rentals, and hotel rooms — they handle strong Mediterranean light well and last for years, but they collect dust, cooking grease, and sea-salt haze faster than most window treatments. The video above from Blinds.com walks through the core technique in minutes; this article goes deeper with step-by-step instructions, material-specific tips, and answers to the questions most homeowners ask first. Follow this routine once a month and your slats will stay bright without ever needing a full replacement.
Why Vertical Blinds Need a Different Approach
Unlike horizontal Venetian blinds, vertical slats hang freely and rotate 180 degrees, which means dirt builds up on both faces and along the top rail where the clips sit. Standard dusting with a cloth often just moves grime from one slat to the next, leaving streaks.
The material of the slat — PVC, fabric, or aluminium — determines how wet you can get it. PVC and aluminium tolerate a damp wipe and even a brief soak, while fabric slats (common in Greek holiday villas for their soft diffused light) need a gentler hand-wash or a delicate machine cycle.
What You Will Need
Gather your supplies before you start: a vacuum cleaner with a brush attachment, two microfibre cloths, a bucket of warm water, a few drops of mild dish soap or white vinegar, and a soft-bristle brush for stubborn spots. For fabric slats you will also want access to a bathtub or large sink. Having everything ready means you do not have to stop mid-clean and risk leaving wet slats to re-attract dust.
5 Steps to Clean Vertical Blinds
- 1
Vacuum both faces of every slat
Close the slats flat on one side and run the vacuum brush attachment from the top of each slat to the bottom using light, even pressure. Rotate the slats 180 degrees and repeat on the other face. This removes the bulk of loose dust before any moisture touches the surface, which prevents you from smearing grime into the material.

Wipe down PVC or aluminium slats with a damp cloth
Mix a few drops of dish soap into a bucket of warm water. Dampen a microfibre cloth — wrung out so it is just barely moist — and wipe each slat from top to bottom on both sides. For grease marks near kitchen windows, substitute white vinegar diluted 1:3 with water; it cuts through cooking residue without leaving a residue of its own. Dry immediately with a second clean cloth to prevent water spots.

Hand-wash or machine-wash fabric slats
Unhook fabric slats from their top clips by pressing the clip tab and sliding the slat out. Lay them flat in a bathtub filled with cool water and a capful of gentle laundry detergent. Gently agitate, rinse thoroughly, and hang to drip-dry in the shade — direct Greek summer sun can bleach the colour and warp the stiffening insert. If the care label permits, a delicate machine cycle in a mesh laundry bag also works well.

Clean the top rail and clips
The head rail collects the most concentrated dust because air circulates through the mechanism whenever the blinds are opened or closed. Use a dry paintbrush or a cotton swab to dislodge dust from inside the rail channel, then wipe the outer casing with a damp cloth. Check each clip for cracks while you work — a broken clip causes a slat to hang crooked and is inexpensive to replace.
- 5
Re-hang and test the rotation
Slide fabric slats back into their clips once fully dry, or confirm the wipe-down slats are dry to the touch before closing them. Draw the blinds fully open and closed once to confirm every slat rotates freely and hangs plumb. If a slat twists or jams, check that its clip is seated evenly in the rail. Finish by standing back and checking the overall alignment from across the room — uneven slats are usually fixed by a gentle manual straighten.

FAQ
- Can I clean vertical blinds without taking them down?
- Yes, for PVC and aluminium slats you should leave them hanging. Vacuuming and wiping in place is faster, safer, and avoids any risk of bending the slats during removal. Only fabric slats genuinely benefit from being taken down, because they need a proper soak and rinse that is impractical to do on the rail.
- How often should vertical blinds be cleaned in a holiday rental or hotel room?
- A quick dust with the vacuum brush should be part of every changeover clean. A full damp-wipe takes only 15-20 minutes and is worth doing monthly in coastal properties where salt haze settles on surfaces, or every 6-8 weeks in inland apartments. Deep-cleaning fabric slats twice a year is usually sufficient unless there is a specific stain.
- My blinds still look yellowish after cleaning — what can I do?
- Yellowing on white PVC slats is usually UV oxidation, not dirt, and cannot be fully reversed by cleaning. A paste of baking soda and a little water left on the slat for 10 minutes before rinsing can brighten them slightly. For severe discolouration, replacement slats are sold individually and are generally inexpensive — often cheaper than the labour cost of professional whitening treatments.
