Blinds are the number one thing people forget and the number one thing they notice when sun hits them. Here's how to do them in place, by material, without warping anything.
Joseph here. Blinds are a strange surface. Nobody thinks about them for months, then the afternoon sun comes through at the right angle and suddenly every slat looks like it's been in storage. In the Triangle it's worse than most places — pollen season coats everything, and HVAC running nine months a year keeps pushing dust toward the windows.
You don't need to take them down. Taking blinds down is where people break them.
The in-place method that works on almost everything
Close the slats one direction. Put an old cotton sock over your hand, dampen it slightly, and run your hand along each slat from the center outward — fingers above, thumb below, so you get both faces in one pass. Flip the slats the other way and repeat. A microfiber duster with flexible arms does the same job if you'd rather not wear the sock.
Do a dry pass first if the blinds are genuinely dusty. Same rule as baseboards: wet dust becomes mud.
By material
Faux wood and vinyl
The forgiving ones. Damp cloth with a drop of dish soap, dry afterward with a second cloth so you don't leave water spots. These are the only blinds you can reasonably wash off outside or in a tub if they're truly filthy.
Real wood
Treat them like furniture. Dry dusting, then a barely-damp wipe and an immediate dry. Water sitting on real wood slats lifts the finish and the warping is permanent.
Aluminum mini blinds
Thin, bendy and easy to crease. Support each slat from underneath as you wipe — don't press down against air. A creased mini blind never sits flat again.
Fabric, cellular and vertical blinds
Vacuum only, with the upholstery brush on low suction. Dab marks with a damp cloth and let them air dry fully. Wetting a cellular shade through collapses the honeycomb.
How to keep them from getting bad again
- Quick dust once a month — it's two minutes a window when they're not loaded.
- Run them closed when the HVAC is on hardest; less air moves across the faces.
- Change the furnace filter on schedule. Dusty blinds are usually a filter story.
- Kitchen blinds need a degreasing wipe, not just dusting — grease holds dust.
Where this lands on a cleaning quote
Blinds are a scope item, not a standard line. Dusting the tops is normal on a visit; wiping every slat in a house full of windows is real time, so we ask about it before quoting rather than surprising you. If you want them handled, say so when you book — it's one of the add-ons listed on our services page.

I started Fancy Pants because I got tired of watching good cleaners get squeezed and good homeowners get surprised by a bill. I still work homes every week across Raleigh, Durham, Cary and Chapel Hill, so these posts come from the checklist in my head — not a content calendar. Ask anyone on my crew: I am the guy who keeps adding "while we're in there" items.
