How To Clean Mould off Roller Blinds

Mould is an unsightly and unhealthy issue that can quickly develop on roller blinds due to moisture, humidity, and lack of ventilation. In New Zealand, where weather conditions can vary from humid summers to damp winters, mould growth becomes a common household issue.

If left untreated, it can cause allergies, respiratory problems, and even permanent damage to your blinds. Understanding how to clean mould off roller blinds properly is essential for maintaining a fresh and healthy indoor environment. 

Why Mould Grows on Roller Blinds? 

Where it’s damp, dark, and poorly ventilated areas, mould finds the perfect place to spread. In New Zealand, high humidity levels during summer and excess moisture in winter create the perfect conditions for mould to develop on roller blinds. Bathrooms, kitchens, and rooms with limited airflow are the most vulnerable spots. Here are some key reasons why mould may form on your blinds: 

Moisture Buildup: Condensation from windows or excess humidity creates the perfect breeding ground for mould spores. 

Lack of Ventilation: Poor air circulation traps moisture, allowing mould to develop on fabric surfaces. 

Dust and Dirt Accumulation: Roller blinds that are not cleaned regularly collect dust, which provides nutrients for mould to grow. 

Darkness and Warmth: Mould thrives in dark spaces, making blinds that are always rolled up more susceptible to infestation. 

Now that you understand why mould forms, let's dive into the cleaning process. 

How to Clean Mould Off Roller Blinds: Step-by-Step Guide 

Step 1. Gather Your Cleaning Supplies 

Make sure you have all the necessary items before you start. Using the wrong cleaning products can damage your blinds or fail to remove the mould effectively. 

Here’s what you’ll need: 

Item	Purpose
White vinegar	Natural mould remover
Baking soda	Deodorises and breaks down stains
Mild detergent	Cleans the blinds without damaging them
Soft cloth/sponge	Prevents damage while scrubbing
Soft-bristled brush	Loosens stubborn mould patches
Spray bottle	Helps evenly distribute cleaning solution
Bucket of warm water	For rinsing off the solution
Rubber gloves	Protects hands from cleaning chemicals
Face mask	Prevents inhaling mould spores
Microfibre towel	Helps in drying the blinds quickly

Step 2: Take Safety Precautions 

Mould spores can cause health problems when inhaled, so it’s essential to wear protective gloves and a mask while cleaning. Open windows or turn on a fan to improve ventilation in the room.  

Step 3. Take Down the Roller Blinds (If Possible) 

Removing the blinds from the window makes cleaning easier, especially if the mould infestation is extensive. If the blinds are fixed and cannot be taken down, clean them while they are still hanging. Ensure the room is well-ventilated to prevent inhaling mould spores. 

Step 4. Dust Off Loose Mould Spores 

Before applying any liquid solution, use a dry microfibre cloth or a vacuum cleaner with a brush attachment to remove loose mould spores. This prevents excess moisture from pushing the mould deeper into the fabric. Be gentle to avoid spreading the spores into the air. 

Step 5. Apply a Natural Mould Remover 

One of the best ways to kill mould is by using natural cleaners such as white vinegar or a baking soda solution. Here’s how to make and use these solutions: 

Option 1: White Vinegar Solution 

In a spray bottle, create a solution using equal volumes of white vinegar and water. Spray the affected areas generously and let them sit for 30–60 minutes before scrubbing with a sponge. 

Option 2: Baking Soda Paste 

Add a bit of water to baking soda and stir until you have a paste. Apply it to mouldy spots and let it sit for 15 minutes before scrubbing. 

Option 3: Hydrogen Peroxide for Stubborn Mould 

For heavy mould infestation, apply 3% hydrogen peroxide directly onto the affected areas and let it sit for 10 minutes. Then wipe with a clean damp cloth. 

Step 6. Scrub Away the Mould 

Using a soft cloth or sponge, gently scrub the mouldy areas in circular motions. For stubborn patches, a soft-bristled brush can help lift the mould without damaging the fabric. Avoid using excessive force, as this may weaken the material. 

If vinegar alone does not remove all the mould, you can use a mild detergent solution. Mix a few drops of detergent in a bucket of warm water and repeat the scrubbing process. 

Step 7. Rinse and Wipe Down the Blinds 

Once the mould is removed, take a clean damp cloth and wipe away any remaining residue. If the blinds were taken down, rinse them with clean water and wipe them dry. If they are still hanging, use a fresh cloth to ensure no cleaning solution remains on the fabric. 

Step 8. Dry the Blinds Completely 

Drying is a crucial step to prevent mould from coming back. Hang the blinds in a well-ventilated area or under direct sunlight. In New Zealand, where sunlight levels vary seasonally, take advantage of sunny days to air out the blinds. Sunlight is a natural mould killer and helps to speed up the drying process.  

If you’re indoors, use a fan or a dehumidifier to remove excess moisture from the air. 

How to Prevent Mould Growth on Roller Blinds 

Cleaning your blinds is only half the battle—preventing mould from returning is just as important. Here are some simple but effective prevention tips: 

Improve Ventilation: Ensure proper airflow in your home, especially in rooms prone to moisture buildup, such as bathrooms and kitchens. Open windows frequently and use exhaust fans where necessary. 

Use a Dehumidifier: A dehumidifier helps keep moisture levels in check and prevent mould growth, particularly during New Zealand’s wet winters. Ideally, indoor humidity should be kept below 60% to prevent mould formation. 

Regular Cleaning: Dust and wipe down your blinds regularly with a mild detergent solution to prevent mould spores from settling. 

Apply a Mould-Resistant Spray: Using a mould-resistant fabric spray on your blinds can provide an extra layer of protection, reducing the chances of future mould growth. 

Check for Window Condensation: Condensation on windows is a major culprit behind mould formation. Wipe down excess moisture daily and ensure proper insulation to prevent condensation. 

When to Replace Your Roller Blinds? 

Sometimes, despite your best efforts, mould can cause permanent staining or damage to your blinds. Here are some signs that it’s time to replace them: 

• The mould has deeply penetrated the fabric, causing permanent stains.  

• The blinds have a strong, musty odour even after cleaning.  

• The fabric has become weak or brittle due to excessive moisture.  

• You have persistent allergy symptoms, indicating hidden mould growth. 

If your blinds are beyond repair, consider replacing them with mould-resistant blinds like PVC blinds, aluminium blinds, or wooden blinds, which are better suited to New Zealand’s variable climate.
