Why Blinds and Curtains Catch People Out at Inspection

Most tenants spend their final week scrubbing ovens, descaling taps and steaming carpets, then walk straight past the one thing hanging in every room. Blinds and curtains collect an astonishing amount of dust, kitchen grease and general grime over a tenancy, largely because nobody thinks to touch them between move-in and move-out. A landlord or inspector, on the other hand, tends to check them first, simply because they’re at eye level and impossible to miss. Grey, dusty slats or curtains with a visible tide mark near the hem are an easy flag on an inspection report, and an easy route to a deposit deduction that could have been avoided with an hour’s work.

The other reason this gets overlooked is that people assume blinds and curtains are “fixtures” the landlord deals with, when in most tenancy agreements they’re treated the same as any other furnishing left in your care. If they were clean when you moved in, they need to be clean when you leave. That’s the standard most landlord inspections are measured against, and it’s worth keeping in mind as you work through your moving out checklist.

Cleaning Venetian and Aluminium Blinds

Metal and aluminium venetian blinds are usually the easiest to bring back to a presentable state, but they’re also the ones people clean badly, because dusting alone rarely shifts the greasy film that builds up in kitchens. Start dry: close the slats fully and run a microfibre duster or a soft brush attachment along each one, working top to bottom. Once the loose dust is gone, wipe each slat with a cloth lightly dampened in warm water with a small amount of washing-up liquid, then turn the blind the other way and repeat on the reverse side. Avoid soaking aluminium blinds or spraying cleaner directly onto them, as water can creep into the mechanism at the top and cause the cords to stiffen or the tilt mechanism to seize.

Wooden and Faux Wood Blinds

Real wood blinds are the ones most likely to be ruined by an overenthusiastic clean, so a lighter touch is essential. Dust them the same way as venetian blinds, slat by slat, then use a cloth that’s been wrung out until it’s barely damp rather than wet. Never soak or submerge wooden slats, and steer clear of ammonia-based sprays, as they strip the finish and leave the wood looking patchy or faded. Faux wood blinds, made from PVC or composite material, are more forgiving and can handle a slightly wetter cloth and a mild all-purpose cleaner, but it’s still worth testing on a small section first if you’re unsure what the finish is.

Vertical Fabric Blinds

Vertical blinds are usually made from a stiffened polyester fabric, and most of the dirt on them is dust rather than grease, so a vacuum with a brush attachment run gently down each slat often does most of the work. For marks or spots, particularly around the bottom where hands and pets tend to make contact, spot clean with a barely damp cloth and mild detergent, working in the direction of the fabric weave rather than scrubbing in circles, which can leave a shiny patch. If a slat is badly stained or has started to curl, it’s often better to check whether replacement slats are available rather than risk damaging the whole set trying to force it clean.

Roller Blinds

Roller blinds tend to be the quickest to deal with, since most are a single flat piece of fabric or PVC that can be wiped down without dismantling anything. Unroll it fully and wipe from top to bottom with a damp cloth and mild cleaner, letting it dry unrolled so it doesn’t stick to itself. Blackout roller blinds with a rubberised backing shouldn’t be soaked, as excess moisture can cause the backing to peel away from the fabric over time.

Machine-Washable Curtains

Lightweight cotton or polyester curtains are usually machine-washable, but the care label is the only reliable way to know for certain, so check it before you do anything else. Remove any hooks, rings or weighted hems first, wash on a cool or gentle cycle, and avoid overloading the machine, since curtains need room to move if you want an even clean. Tumble drying is often where things go wrong, so unless the label specifically allows it, air dry instead.

Dry-Clean-Only, Heavy and Lined Curtains

Heavier curtains, particularly anything lined, interlined or made from velvet, wool or a delicate silk blend, should not go anywhere near a domestic washing machine. These are almost always marked dry-clean-only, and for good reason: the lining and the outer fabric often shrink at different rates, which leaves the curtain puckered and misshapen if it’s washed at home. For these, a light vacuum with a soft brush attachment to lift dust, followed by a trip to a dry cleaner if they’re genuinely soiled, is the safer route. This is one of the few areas where trying to save money can end up costing more, since a warped or shrunken curtain is far harder to explain away at inspection than a cleaning receipt.

Limescale and Grease Near Kitchen and Bathroom Windows

Windows in kitchens and bathrooms tend to have their own particular grime, and it often creeps onto nearby blinds or curtain hems without anyone noticing until moving day. Limescale around a bathroom windowsill responds well to a mix of white vinegar and warm water left to sit for a few minutes before wiping, though it’s worth protecting any wooden or painted surfaces nearby, as vinegar isn’t kind to every finish. Grease near a kitchen window usually needs a proper degreaser or a warm water and washing-up liquid solution rather than a quick wipe, since grease left too long tends to bond with dust and turn into a sticky film that ordinary cleaning sprays won’t shift on the first attempt.

Drying and Rehanging Without Losing Shape

However you’ve washed your curtains, how you dry them matters just as much. Hanging curtains back up while they’re still slightly damp, rather than waiting for them to dry flat or scrunched in a basket, lets gravity do the work of pulling out creases and keeping the fabric hanging correctly. Avoid direct heat sources like radiators for drying, as uneven heat can shrink one section of fabric more than another and leave a curtain that no longer sits straight. If you’ve removed hooks or rings, put them back before the curtain is fully dry so the weight settles evenly along the top edge rather than bunching in places.

When to Call in a Professional

There’s no shame in handing this over, particularly with heavy lined curtains, blinds with a delicate finish, or anything showing signs of damage rather than just dirt. A professional end of tenancy cleaning service will know which methods suit which materials, has the right equipment for anything beyond a domestic clean, and can usually turn a job like this around far faster than a DIY attempt squeezed in between packing boxes. If you’re already paying for a full end-of-tenancy clean, it’s worth checking whether blinds and curtains are included, since bundling it in is often cheaper than a separate specialist visit.
