How To Clean Vertical Blinds

Vertical blinds are a popular choice in many Australian homes. They provide excellent light control and privacy, and they’re well-suited for large windows or sliding doors. However, over time, they attract dust, stains and moisture, which can make them look tired or unclean.

Whether your blinds are made of fabric or vinyl, they need regular attention to stay in good condition. If neglected, they may become discoloured, hold odours or develop mould. This guide covers how to clean blinds properly, including how to clean them without removing them, treat stains and keep them in good shape through all seasons.

What you’ll need before you start

Having the right supplies will help you clean more efficiently, reach tricky areas and avoid damaging your blinds during the process. Preparing everything in advance will also help reduce mess and make the job quicker.

Gather the following:

• Vacuum with a soft brush attachment —  Useful for gently removing dust and loose debris from both fabric and vinyl slats without scratching or tugging at the material.
• Bucket of warm water — Needed for mixing your cleaning solution and rinsing your cloths as you go. Make sure the water isn’t too hot, especially for fabric blinds.
• Mild detergent or dishwashing liquid — A small amount added to warm water is effective for lifting dirt and grime without being too harsh on delicate materials.
• Microfibre cloths or soft sponge — These are ideal for wiping slats clean. They’re non-abrasive, won’t leave lint behind and work well with both wet and dry methods.
• White vinegar and bicarb soda — Natural and effective options for stain removal, grease build-up and mould prevention. They’re safe to use on most blind surfaces when applied correctly.
• Old toothbrush or soft scrubbing brush — Helpful for scrubbing small spots or textured stains gently, particularly in corners or creases that are hard to reach with a cloth.
• Towel or drop sheet for protecting the floor — Place this underneath the blinds to catch drips, dust or cleaning solution. It helps protect carpet, tiles or timber flooring while you clean.
• Stepladder if your blinds are mounted high — Allows you to reach the top of tall blinds safely and clean from a stable, comfortable position without stretching.

Cleaning vertical blinds without removing them

In most cases, you can clean blinds without removing them from their brackets. This method is convenient, less time-consuming and ideal for regular upkeep. With the right tools and approach, you can clean effectively while keeping the blinds in place.

Here’s how to do it step by step:

1. Close the blinds so the slats face in one direction.
2. Use a vacuum with a brush attachment or a dry microfibre cloth to remove surface dust.
3. Tilt the blinds in the other direction and repeat the process.
4. Use a damp cloth with mild soapy water to wipe each slat from top to bottom.
5. For vinyl slats, rinse the cloth often to remove grease and dust.
6. For fabric slats, use a dabbing motion to avoid pulling or damaging the material.
7. Dry the blinds using a clean towel or let them air dry with good airflow.

Cleaning vertical blinds in place like this is ideal for regular maintenance and helps prevent dust build-up from becoming a bigger issue.

How to remove stains from vertical blinds

Stains are common on vertical blinds, whether from cooking residue, pets, moisture or everyday use. Cleaning techniques differ slightly depending on the material.

Fabric vertical blind cleaning

• Mix equal parts white vinegar and warm water in a spray bottle.
• Spray the stained area lightly and blot gently with a clean cloth.
• For deeper stains, make a paste using bicarb soda and a few drops of water.
• Apply the paste to the stain, then scrub gently using an old toothbrush.
• Dab with a clean, damp cloth to remove residue, then allow to air dry.

How to clean vinyl blinds

• Wipe with a soft sponge dipped in warm, soapy water.
• For tougher spots, add a small amount of white vinegar to the solution.
• Scrub lightly using a cloth or soft brush.
• Rinse with clean water and wipe dry with a towel.

If you’re unsure of how the material will react, always test your cleaning solution on a small hidden section first.

How to clean mould from blinds

Mould is common in humid rooms like bathrooms and kitchens. It appears as dark spots and can produce a musty smell. It can also trigger allergies and affect indoor air quality. 

Here’s how to clean mould from blinds effectively:

• Mix equal parts vinegar and water in a spray bottle.
• Spray directly onto the mould-affected area.
• Let the solution sit for 5 to 10 minutes.
• Gently scrub with a toothbrush or cloth until the mould is removed.
• Rinse the area with a damp cloth and dry thoroughly.

Make sure the room is well ventilated during and after cleaning. If the mould keeps returning, increase airflow by opening windows or using an exhaust fan.

How to maintain vertical blinds

Regular maintenance can prevent problems such as discolouration, mould and mechanical wear. Below are practical tips to maintain vertical blinds in the long term:

• Dust blinds weekly using a microfibre cloth or vacuum
• Clean high-moisture areas like kitchens and bathrooms more often
• Wipe down slats after humid weather or rainy days
• Avoid closing blinds while they are still damp
• Open windows for airflow to prevent trapped humidity
• Rotate blinds slightly during the day to reduce fading from sunlight
• Consider deep cleaning every few months, particularly in summer

Keeping to a routine helps prevent deep stains and saves time down the track.

Climate tips for cleaning vertical blinds in Australia

Australia’s weather plays a big role in how often and how thoroughly you should clean your blinds. From dry inland heat to coastal humidity, each condition affects your cleaning needs differently.

In humid regions or during summer:

Moisture tends to cling to vertical blinds during warmer months, creating the perfect conditions for mould to develop. This is particularly common in bathrooms, laundries and coastal areas. To stay ahead of it, clean your blinds more often during summer and use a vinegar spray weekly to help prevent mould from forming on both fabric and vinyl slats. Always ensure blinds are completely dry before closing them, as trapped moisture can lead to musty smells and long-term damage.

In dry and dusty regions:

Inland and arid areas often see a faster build-up of fine dust, which settles easily on blinds. Both fabric and vinyl materials can collect dust, making regular wiping essential. Use a slightly damp cloth rather than a dry one to lift dust more effectively without sending it into the air. It also helps to clean window sills, tracks and surrounding surfaces, as dust from these spots often finds its way onto the blinds.

During bushfire season:

Smoke and fine ash from nearby fires can cling to blinds, leaving behind residue or causing discolouration, particularly on light-coloured vinyl. To manage this, gently wipe down the slats using a soft cloth with water and mild detergent. Keep windows closed during poor air quality periods and only open them once conditions have improved to reduce the amount of smoke that enters your home.
