Curtain & Blind Care Guide
How to wash, dry, iron and maintain curtains and blinds - with fabric-specific guidance and tips for Cape Town's UV, dust and coastal conditions.
How often should you clean curtains?
Curtains collect dust, cooking grease, moisture and UV-degraded fibres at different rates depending on the room. Kitchen and bathroom curtains need cleaning four times a year; a study or office curtain needs cleaning once.
Recommended cleaning frequency by room
A "clean" means a full wash for washable fabrics, or a thorough vacuum and spot-clean for dry-clean or delicate fabrics. More frequent spot-cleaning as needed is always worthwhile.
Cape Town-specific care considerations
Cape Town's climate puts specific demands on curtains that most generic care guides do not address.
UV degradation
Cape Town has some of the highest UV index readings in the southern hemisphere. Direct sun through unprotected windows bleaches and weakens fabric within 2-3 years. UV-rated polyester and a lined curtain (which protects the face fabric) are the two most effective defences.
Cape Doctor dust
The south-easter deposits fine dust across the entire metro. Curtains in rooms with windows left open during summer accumulate dust noticeably faster - vacuum monthly during the Cape Doctor season (September to March) rather than waiting for a full wash.
Winter damp and mould
Cold, wet winters create condensation on windows. Curtains that rest against cold glass or walls develop mould spots. Leave a 5-10 cm gap between the curtain and the window, and ventilate rooms daily. Treat any mould with white vinegar solution before it sets.
Coastal salt air
Within a few kilometres of the coast, salt particles accelerate corrosion on metal components (hooks, rings, blind mechanisms) and leave a residue on fabric. Rinse outdoor-facing blinds and metal hardware more frequently - monthly wipe-downs prevent build-up.
Reading care label symbols
Care labels use international symbols. These are the ones you will see most often on curtain fabrics.
How to wash curtains at home
Follow these steps to wash curtains safely without risking shrinkage or damage.
Check the care label
Read the label sewn into the lining or heading tape before anything else. If it says dry clean only, take it to a dry cleaner - home washing risks permanent shrinkage or colour bleed.
Remove hooks, rings and weights
Take out all curtain hooks, clip rings, and lead weights from the hem. Metal hardware damages the drum and tears fabric. Put small hardware in a mesh laundry bag.
Shake out loose dust outside
Shake the curtains outdoors before washing. This removes surface dust and prevents a dusty rinse from re-settling into the fabric. A quick vacuum on low with an upholstery attachment also works.
Wash on gentle at the correct temperature
Use a delicate cycle. Polyester washes at 30°C, cotton up to 40°C if the label allows. Use a mild detergent - no bleach or optical brighteners, which yellow fabric over time.
Hang immediately while damp
Remove from the machine as soon as the cycle ends and hang back on the track or a line while still damp. The weight of the wet fabric pulls out most creases. Avoid tumble drying unless the label explicitly allows it.
Curtains that have shrunk, faded badly, or developed mould that will not shift may be worth replacing. We will give you an honest assessment.

Different fabrics need different care. Use this table as a quick reference alongside your curtain's care label.
| Fabric | Wash method | Max temp | Iron | Notes |
|---|---|---|---|---|
| Polyester / synthetic | Machine wash | 30°C | Low (110°C) | Most curtain fabrics. Holds colour well, resists shrinkage. |
| Cotton / polycotton | Machine wash | 40°C max | Medium (150°C) | Check label first - untreated cotton can shrink up to 5-7% at 60°C. |
| Linen blend | Machine wash | 30°C max | High (200°C) - damp | Linen creases easily. Iron while damp for best results. |
| Velvet | Dry clean or hand wash | Cold only | Do not iron | Steam from the reverse side only. Never iron the pile directly. |
| Sheer / voile | Machine wash | 30°C | Low (110°C) | Wash separately - sheers snag on heavier fabrics. Hang immediately. |
| Blackout lining | Hand wash or wipe | Cold only | Low (back only) | Machine washing can peel or crack the blackout coating. Spot-clean where possible. |
Blind care by type
Blinds collect dust on slats and fabric surfaces and need different maintenance to curtains.
| Blind type | How to clean | Avoid | Frequency |
|---|---|---|---|
| Roller blind (fabric) | Vacuum with brush attachment, spot-clean stains | Immersion in water - the roller mechanism corrodes and fabric warps | 3-4x/year dust; spot-clean as needed |
| Roller blind (PVC / blackout) | Wipe with damp cloth and mild detergent | Abrasive cleaners that scratch the surface coating | Monthly wipe-down in kitchens and bathrooms |
| Aluminium Venetian | Wipe each slat with a damp microfibre cloth or Venetian duster | Leaving wet for extended periods near the ladder tape | 2x/year full clean; monthly quick dust |
| Timber Venetian | Dry dust only with a microfibre cloth or feather duster | Water and steam - causes warping and swelling of real wood | 2-3x/year; keep away from moisture-prone rooms |
| Vertical blind (fabric) | Vacuum with upholstery attachment; spot-clean stains | Machine washing individual louvres - most shrink and lose shape | 2x/year |
| Vertical blind (PVC) | Wipe with damp cloth; mild detergent for stubborn marks | Solvents which cloud the surface | Monthly wipe-down |
Common problems and fixes
Curtains shrank after washing
Prevention only - once shrunk, fabric cannot be reliably stretched. Wash at 30°C on gentle and always check the label. If curtains are now too short, a hem extension may be possible.
Mould or mildew spots
Soak washable fabrics in 1 part white vinegar to 4 parts cold water for 30 minutes, then wash at the maximum label temperature. For dry-clean fabrics, take to a professional and mention the mould - some home treatments set the stain permanently.
Fading from UV
Fading is irreversible. Slow it down by adding a lining or an interior UV-filter roller blind. Replace with a UV-rated polyester fabric in sun-facing rooms. Rotate sheer panels regularly so UV exposure is even across the fabric.
Curtains won't hang straight after washing
Hang while still damp and let gravity do the work. If creases remain, steam from a garment steamer held 10-15 cm away is the safest method. Iron only on the correct heat setting, from the reverse side for velvet and sheers.
Rust marks from metal hooks or rings
Remove all metal hardware before washing. Treat rust marks on fabric with a paste of lemon juice and salt left for 30 minutes before washing, or use a commercial rust remover rated for fabric. Replace any corroded hooks - they will re-stain the fabric.
Blind slats bent or warped
Aluminium slats can sometimes be gently straightened by hand. Warped timber slats caused by moisture exposure cannot be fixed - replace the affected louvres. To prevent warping, keep timber Venetians away from kitchens and bathrooms.
Storing curtains correctly
Curtains taken down during a move or renovation need to be stored carefully to avoid permanent creases, yellowing and pest damage.
Wash before storing
Always wash or dry-clean before storing. Soiled fabric attracts insects and the stains oxidise and set permanently over months in storage.
Store in breathable bags
Use cotton bags or pillowcases, never plastic. Plastic traps moisture and causes yellowing and mould within weeks in a Cape Town winter.
Fold along pleat lines
Fold loosely following the existing pleat lines rather than flattening the heading tape. This preserves the shape and reduces the ironing needed when you rehang.
Cool, dark and dry
Store away from direct sunlight (UV degrades fabric even through glass), damp walls, and heat sources. A linen cupboard is ideal; a garage is not.
