Keeping curtains alive, and washing them without wrecking them

What happens if you don't

• Settled dust is not passive. Dust grains have sharp edges, and every time the curtain moves they saw against the fibres. The fabric wears out sooner than it should.
• In air-conditioned rooms, moisture off the coil binds the dust into a film. Once it films, it is far harder to wash out than dry dust.
• In homes with dust allergies or small children, curtains are the collection point everyone overlooks, because nobody touches them daily.
• The obvious sign is colour: long-settled dust dulls the whole panel. People blame sun fading when the fabric is simply dirty.

The routine that actually matters

• Brush or vacuum lightly once a month — soft brush head, lowest suction, work from the top down
• Let some air through the room — a permanently sealed room goes stale and the fabric holds the smell
• Deal with marks immediately — blot with a clean, barely damp cloth. Never rub: rubbing drives the stain deeper and raises the fibres
• Don't let the hem drag on the floor — a dragging hem always blackens and frays before anything else

Taking a Roman blind down to wash — doable if you note the order

Roman blinds are the ones people are most afraid to take down, because of the cords and rods behind them. The hard part is not removing it, it is remembering how it was. Photograph the back of the blind first — two or three shots.

1. Let it all the way down so the fabric is flat and every cord and ring is visible
2. Photograph the back — which rings the cords run through, and where they are tied
3. Release the cords at the bottom rings, usually two to four of them depending on width
4. Gather the cords hanging from the rail and tie them loosely together. This is the step that matters: left loose they tangle into something you cannot undo
5. Pull the fabric off the rail. Most Roman blinds hold on with hook-and-loop tape — peel slowly from one corner across
6. Slide the rods out of their pockets. One end of each pocket is stitched shut; unpick that thread, draw the rod out, and bundle the rods together
7. Label everything. With several blinds, write down which panel belongs to which window — a few centimetres of difference is enough that they cannot be swapped

Five things that ruin a curtain outright

• Tumble drying — heat and spin shrink the panel unevenly, and a shrunk curtain cannot be lengthened again
• Bleach — it destroys both the colour and the fibre, especially on light-blocking coated fabrics
• A hot iron straight on the cloth — much curtain fabric is polyester, and polyester melts. Low heat through a pressing cloth if you must
• Washing it with anything that has hooks or zips — they snag long pulls into the weave that never come out
• Drying it in hard sun while wet — wet fabric in strong sun fades unevenly. Shade with moving air is best
