How to Clean Blinds in South Africa

The right method for each material. No professional cleaning services exist in South Africa — this guide is how you protect what you have spent money on.

To clean blinds properly, dust weekly with a dry microfibre cloth, working from top to bottom with the blind fully extended. For a deeper monthly clean, wipe with a cloth wrung almost dry in warm water with a few drops of mild dish soap. Match the method to the material: damp cloth for rollers and PVC, bathtub soak for aluminium venetians, dry cloth only for real wood. Never roll a blind up wet — trapped moisture causes mould inside the roll within days. In coastal South African homes, a weekly fresh-water rinse on outdoor blinds prevents salt from corroding hardware.

How do you clean blinds properly?

  • Dust weekly with a dry microfibre cloth, working top to bottom with the blind fully extended
  • Monthly, wipe with a cloth wrung almost dry in warm water with a few drops of mild dish soap
  • Never roll a blind up wet — trapped moisture causes mould inside the roll within days
  • Aluminium and PVC venetians can be submerged in a bath of warm soapy water for deep cleaning
  • Wood and bamboo blinds must never be soaked — use a damp cloth and dry immediately
  • Sheer fabrics like Shademaster by Crawford’s are inherently mould-resistant, ideal for coastal South African homes
  • For shutters, clean behind every louvre groove and leave blades slightly open when the house is unoccupied
  • Custom Blinds recommends a seasonal deep clean and weekly light dusting to extend blind life by years

TLDR

Dust weekly, damp-wipe monthly, never roll up wet. Each material has its own method — roller, venetian, honeycomb, wood, sheer and outdoor blinds all clean differently. Shutters need attention behind the grooves. Mould is the real enemy in coastal SA homes, and the right fabric choice prevents it entirely.

Clean blinds change a room instantly. Light comes through clearly. Dust stops circulating. The air smells different. It takes ten minutes, and the house feels like it did the day everything was installed.

“Ninety percent of the blind replacements I quote could have been avoided with a cloth and five minutes a week. The fabric was fine. The mould was not.”

How do you clean roller blinds?

Roller blinds are the most popular blind in South Africa and among the easiest to maintain. The critical rule is simple: never roll a blind up while it is still damp. Trapped moisture causes mould inside the roll within days, particularly in humid coastal areas like the Garden Route, KZN and the Western Cape. If staining has set in beyond what cleaning can shift, it may be time to replace rather than persist. Blockout roller blinds start from R583 with free delivery nationwide.

5 steps to clean roller blinds

  1. Extend fully. Lower the blind to its full length so the entire fabric surface is accessible.
  2. Dust top to bottom. Run a dry microfibre cloth in straight downward strokes. For sheer roller blinds, use a vacuum on low suction with a brush attachment — the fabric is too delicate for friction.
  3. Damp-wipe monthly. Mix a few drops of Sunlight Liquid or mild dish soap in warm water. Wring your cloth almost dry and wipe in downward strokes. Rinse the cloth in clean water and go over the blind again.
  4. Spot-treat stains. Apply a paste of baking soda and water with a soft cloth. Test on a hidden section first. Avoid bleach — it degrades the UV coating that protects the fabric.
  5. Dry completely before rolling up. Leave the blind hanging fully extended until bone dry. Rolling up a damp blind causes mould inside the roll within days.

Are sheer blinds harder to clean?

Sheer and light-filtering roller blinds require a gentler approach than standard blockout fabrics, but they reward that care with longer life. The open weave structure means dust passes through rather than settling — so they actually stay cleaner between wipes.

Shademaster by Crawford’s — handcrafted in Cape Town since 1885 — uses fabrics engineered for humidity and salt air. The weave is inherently mould-resistant, which makes Shademaster the preferred sheer for coastal homes from Knysna to Ballito. Weekly vacuuming on the lowest suction setting with a brush attachment is all most Shademaster installations need. For marks, a barely damp cloth and patience.

If your sheer blinds have developed permanent dark staining that will not lift after repeated treatment with diluted white vinegar, the mould has penetrated the fibres. At that point, replacement is the only option — but choosing a mould-resistant fabric like Shademaster means the problem does not return.

How do you clean venetian blinds without removing them?

Aluminium and PVC venetian blinds are the most forgiving material to clean. Tilt the slats to about three-quarters closed — not fully overlapping — and wipe each slat from side to side with a dry microfibre cloth. Flip the slats and repeat on the other side.

For kitchen venetians where grease builds up, mix equal parts warm water and white vinegar. Dip your cloth, wring well, and wipe each slat individually. Dry with a clean cloth to prevent water marks. Aluminium and PVC venetians handle moisture well, so you can be more thorough than with other materials.

Deep clean: If the slats are heavily soiled, remove the blind and soak in a bath of warm water with a squirt of dish soap for an hour. Wipe each slat, rinse under clean water, and hang to dry completely before reinstalling. If your slats are bent, discoloured, or the cords are fraying, cleaning will not fix a worn mechanism. Replacement aluminium venetians are made to measure and delivered free.

How do you clean vertical blinds?

Vertical blinds hang from a top track with individual slats that run from ceiling to floor. Dust collects along the flat face of each slat and in the carrier clips at the top where the slats hook in.

Weekly: Dust each slat from top to bottom using a microfibre cloth or a hand-held vacuum cleaner on low suction. Always work downward — pulling upward can unhook the slats from their carriers.

Deep clean: Unhook the slats from the track. For fabric verticals, lay them flat and spot-clean with a cloth dampened in warm water and a few drops of Sunlight Liquid. For PVC or vinyl slats, soak in a bath of warm soapy water, wipe each slat, rinse and hang to dry straight before rehooking.

Tip: Never fold or crease fabric vertical slats during cleaning — the crease line becomes permanent. Lay them flat or hang them over a shower rail to dry.

How do you clean faux wood and Plaswood blinds?

Faux wood and Plaswood venetian blinds combine the look of timber with the moisture resistance of PVC, making them easier to clean than real wood. They will not warp if they get wet, which makes maintenance significantly simpler.

Weekly: Dust with a microfibre cloth or soft duster, tilting slats up and then down to reach both sides. Monthly: Wipe down each slat using warm water with a few drops of Sunlight Liquid. Alternate the slat direction when wiping with Pledge or Mr Min polish to reach both surfaces and restore the finish.

These blinds handle more moisture than real wood, so you can be thorough without worrying about warping — making them a practical choice for kitchens, bathrooms and coastal homes.

How do you clean honeycomb blinds?

Honeycomb blinds trap dust inside their cellular structure, which is excellent for insulation but requires specific cleaning. Use a vacuum with a brush attachment on the lowest suction setting — higher suction can collapse the cells.

A hairdryer on a cool setting is surprisingly effective at blowing dust out of the honeycomb chambers. Direct the airflow along the length of each cell. For spots and stains, blot gently with a damp cloth and mild soap. Never submerge honeycomb blinds in water — the adhesive bonding the cells will weaken. If the cells are damaged or discoloured, order replacement honeycomb blinds made to your exact measurements.

How do you clean wood and bamboo blinds safely?

Real wood and bamboo blinds must never be soaked or exposed to excess moisture. Water warps timber, discolours finishes and weakens bamboo fibres. Treat them the way you would treat wooden furniture.

Weekly: Dust each slat with a dry microfibre cloth or feather duster, following the grain. Monthly: Lightly dampen a cloth — barely moist, not wet — and wipe each slat. Apply a small amount of Mr Min, Pledge or wood-safe polish to restore the finish. Dry immediately.

For stubborn spots, a cloth dampened with white vinegar works on most wood finishes. Always test on a hidden area first. If slats have warped or the finish has lifted, the damage is structural — no amount of cleaning will restore them.

How do you clean shutters — and what do most people miss?

Shutters look clean from a distance, but dirt and dust accumulate in the grooves behind each louvre blade where the blade meets the frame. Most people wipe the flat face and miss these channels entirely. Over months, that hidden grime becomes a breeding ground for mould.

The method: Open the louvres fully. Use a small brush — an old toothbrush works well — to clean inside each groove where the blade pivots. Then wipe each blade front and back with a damp cloth. For PVC and aluminium shutters, mild soapy water is fine. For timber, use a wood-safe cleaner and dry immediately.

Holiday home warning: If your property sits closed for weeks at a time — common on the Garden Route and along the coast — leave shutter blades slightly angled open, never fully closed. A sealed room with no air movement creates the perfect conditions for mould growth behind the louvres. Even a two-degree tilt allows enough ventilation to prevent moisture from settling. Many holiday homeowners return to mould-stained shutters that could have been avoided with this single adjustment.

PVC shutters from brands like Plaswood are naturally mould-resistant and easier to maintain than timber in humid environments. For coastal holiday homes, they are the practical choice. See our full guide to choosing shutters for the Garden Route.

How do you clean outdoor blinds and PVC screens?

Outdoor blinds endure direct sun, wind, rain and salt spray. Clear PVC panels, canvas drops and sheerweave screens each need different care, but all benefit from regular rinsing before dirt has time to bond with the surface.

Clear PVC: Rinse with a garden hose on gentle pressure. For marks, wipe with warm soapy water and a soft cloth. Never use abrasive cleaners or scourers — they scratch the PVC permanently, making it cloudy. Avoid pressure washers.

Canvas and acrylic: Brush off loose dirt when dry. Hose down, then scrub gently with a soft brush and mild soap solution. Rinse thoroughly. Let the blind dry completely before rolling up.

Sheerweave mesh: The open weave stays cleaner than solid fabrics. Vacuum with a brush attachment or hose down. For coastal installations where salt builds up, a monthly fresh-water rinse prevents the salt from degrading the fibres.

How do you remove mould from blinds in South Africa?

Mould is a fact of life in humid South African homes, particularly during Cape winters, in KwaZulu-Natal, and in any coastal bathroom or laundry. The key is catching it early — small dark spots at the bottom of a blind or a musty smell near the window.

Removal: Mix equal parts white vinegar and water in a spray bottle. Spray the affected area and let it sit for ten minutes. Wipe with a clean cloth. For stubborn mould on vinyl or aluminium, a soft-bristle brush helps. Dry the area thoroughly afterwards.

Prevention: The weekly dusting habit is the best prevention. Mould needs dirt and moisture together. Remove the dirt and you remove half the equation. In high-humidity rooms, choose materials that resist mould: aluminium venetians, PVC shutters, and mould-resistant sheer fabrics like Shademaster by Crawford’s.

When to replace: If dark staining will not shift after repeated vinegar treatment, the mould has penetrated the fibres. No cleaning method will restore the blind. Replacing with a mould-resistant fabric prevents the cycle from repeating.

Frequently Asked Questions

How often should you clean blinds in South Africa?

A light dust with a dry microfibre cloth once a week prevents build-up. A deeper clean with a damp cloth and mild soap once a month keeps blinds in good condition. In coastal areas like the Garden Route, where humidity accelerates mould growth, weekly attention is more important than anywhere else.

Can you clean roller blinds without taking them down?

Yes. Extend the blind fully and wipe top to bottom with a dry cloth for weekly dusting or a barely damp cloth for monthly cleaning. There is no need to remove roller blinds from the brackets unless they are heavily soiled and require a full soak.

What is the best way to prevent mould on blinds?

Dust weekly to remove the organic matter mould feeds on. Never roll a blind up while damp. In high-humidity rooms, choose mould-resistant materials such as aluminium venetians, PVC shutters, or Shademaster sheer fabrics. Good ventilation is essential.

Are Shademaster blinds easier to clean than standard sheer fabrics?

Shademaster uses fabrics engineered for humidity and salt air, making them inherently mould-resistant. Weekly vacuuming on low suction is typically all a Shademaster installation requires. See the full Shademaster range.

How do you clean behind shutter louvres?

Open the louvres fully and use a small brush to clean inside the groove where each blade meets the frame. This is where hidden dirt and mould accumulate. Wipe each blade front and back, then leave the louvres slightly open to allow air circulation.

Can you use vinegar to clean blinds?

White vinegar diluted with equal parts water is safe and effective for aluminium, PVC, and vinyl blinds. It cuts through grease and kills mould spores. Avoid vinegar on real wood. For fabric blinds, test on a hidden area first.

Where can I get blinds cleaned professionally in South Africa?

There are no dedicated blind cleaning services in South Africa. This guide is the practical alternative. For replacement blinds, shop online or call Duncan on 079 523 5407.
