How to Clean Vertical Blinds Properly
If you want to know how to clean vertical blinds properly, start by dusting them while hanging, then spot clean with warm water and mild detergent. PVC blinds can be wiped down fully, while fabric blinds should be cleaned gently to avoid distortion. Deep cleaning may require removing the slats and washing them individually, depending on the material.
Before cleaning, always check whether your blinds are fabric, PVC or faux wood. The method depends entirely on the material.
Why Vertical Blinds Get Dirty So Quickly
Vertical blinds collect dust faster than most window coverings because they hang in open air and move regularly. Airflow from windows, radiators and daily movement causes dust to settle along the slats.
Kitchens and bathrooms add grease and moisture into the mix. Over time, this can lead to:
-
Visible dust lines
-
Greasy film
-
Light mould spots
-
Discolouration at the bottom edges
Regular light cleaning prevents the need for heavy washing.
Step 1. Dust the Blinds While Hanging
The simplest way to clean vertical blinds is to start dry.
Close the blinds so they lie flat.
Use a microfibre cloth or a soft brush attachment on your vacuum.
Work from top to bottom.
Turn the blinds the opposite way and repeat.
This removes surface dust without spreading it into the air.
For allergy-prone households, vacuuming is better than dry dusting.
Step 2. Spot Clean Marks and Stains
For small marks:
- Mix warm water with a small amount of mild washing-up liquid.
- Dip a soft cloth into the solution and wring it out well.
- Gently blot the stain rather than rubbing.
Avoid soaking fabric blinds. Excess moisture can cause warping or shrinkage.
Always test on a hidden area first.
How to Clean PVC Vertical Blinds
PVC blinds are easier to clean than fabric.
You can wipe each slat fully with warm soapy water.
For greasy build-up, use a slightly stronger solution, but avoid abrasive pads.
Dry each slat with a clean cloth to prevent water marks.
PVC blinds are more forgiving, but aggressive scrubbing can still scratch the surface.
How to Clean Fabric Vertical Blinds
Fabric requires more care.
If heavily soiled, remove each slat carefully from the headrail. Most unclip individually.
- Lay them flat in a bath with lukewarm water and mild detergent.
- Let them soak for 20–30 minutes.
- Gently wipe along the length of the fabric.
- Rinse thoroughly and hang them back up to dry naturally. This helps them keep their shape.
Do not twist or wring them out.
Can You Wash Vertical Blinds in a Washing Machine?
In most cases, no.
Machine washing can:
-
Distort the fabric
-
Fray edges
-
Damage weights and stitching
Unless the manufacturer explicitly states they are machine washable, avoid it.
How to Remove Mould from Vertical Blinds
Mould can develop in damp rooms.
For light mould on PVC: Use diluted white vinegar on a cloth and wipe gently.
For fabric blinds: Blot with a diluted solution of white vinegar and water. Do not oversaturate.
Persistent mould may require professional cleaning or replacement.
Improving ventilation in the room helps prevent recurrence.
How Often Should You Clean Vertical Blinds?
Light dusting once a month is usually sufficient.
In kitchens or high-traffic rooms, cleaning every two to three weeks keeps build-up under control.
Deep cleaning is typically needed once or twice a year.
What Not to Use on Vertical Blinds
Avoid:
-
Bleach
-
Harsh chemical sprays
-
Steam cleaners on fabric
-
Rough scourers
These can cause fading, distortion or permanent damage.
When to Replace Vertical Blinds
If slats are:
-
Warped
-
Frayed
-
Stained beyond removal
-
Mould-damaged
Replacement may be more practical than restoration.
Regular cleaning keeps blinds looking bright and extends their lifespan. Always follow manufacturer care instructions and test any cleaning solution on a small, hidden section first.
