How To Get Mould Off Curtains

Curtains not only add beauty and functionality to our homes but also provide privacy and protection from sunlight. However, they can be susceptible to mould growth, which not only ruins their appearance but also poses health risks. 


This blog will walk you through the easiest and most effective way to clean mould off your curtains, ensuring a clean and healthy living environment for you and your family.

What causes mould on curtains?

Mould thrives in environments with high humidity, warmth, and limited air circulation. When curtains come into contact with moisture, such as condensation, leaks, or dampness, they become an ideal breeding ground for mould spores. 

Common causes of mould on curtains include high humidity levels, lack of ventilation, water leaks, and insufficient drying after washing.

Excess moisture in the air can be due to various factors like humid weather, poor ventilation, or moisture seeping through walls and windows. Bathrooms, kitchens, and basements are particularly prone to mould growth due to the high levels of humidity and frequent exposure to moisture. If your curtains are in close proximity to these areas, they are more likely to develop mould.

Furthermore, condensation can occur when warm air meets a cold surface, such as windows or poorly insulated walls. If the curtains are hanging near these surfaces, they may absorb the moisture and become a breeding ground for mould.

Why mould is dangerous

Mould growth on curtains not only affects the aesthetic appeal of your home but also poses health risks. Exposure to mould spores can trigger allergic reactions, respiratory problems, and aggravate existing conditions like asthma. 

The presence of mould can cause symptoms such as sneezing, coughing, watery eyes, nasal congestion, and skin irritation.

Some individuals may be more sensitive to mould than others, and prolonged exposure can lead to more severe health issues. People with compromised immune systems, respiratory conditions, or allergies are particularly vulnerable to the adverse effects of mould.

It is crucial to address mould growth promptly to prevent further complications and maintain a healthy indoor environment.

How to get mould off curtains

Cleaning mould off curtains requires a systematic approach and the right tools. Here is a step-by-step process to effectively remove mould from your curtains:

1.Gather the necessary supplies

Before you begin the spot cleaning process, gather the following supplies:

  • Rubber gloves: Protect your hands from direct contact with mould and cleaning solutions.
  • Face mask: Prevent inhalation of mould spores during the cleaning process.
  • Plastic sheet or drop cloth: Place it on the floor beneath the curtains to catch any debris or moisture.
  • Soft-bristle brush or sponge: Use to scrub the mould spots gently.
  • Mild detergent or vinegar solution: Prepare a cleaning solution using a mild detergent or vinegar diluted in water.
  • Spray bottle: Fill it with the cleaning solution for easy application.
  • Clean white cloth: Use for testing the cleaning solution and blotting the curtains.
  • Vacuum cleaner (optional): Can be used with a brush attachment to remove loose mould spores before spot cleaning.

At Briscoes, we offer a wide range of cleaning supplies, including rubber gloves, face masks, spray bottles, and more.

2. Prepare your workspace

To ensure a safe and controlled environment for spot cleaning, follow these steps:

  • Lay a plastic sheet or drop cloth on the floor beneath the curtains to catch any debris or moisture that may fall during the cleaning process.
  • Open windows or use a fan for proper ventilation, allowing fresh air to circulate and prevent the accumulation of cleaning fumes.
  • Wear rubber gloves and a face mask to protect yourself from mould spores and any potential irritants in the cleaning solution.

By taking these precautions, you create a suitable workspace that minimises the spread of mould spores and ensures your safety during the cleaning process.

3. Test the cleaning solution

Before applying any cleaning solution to your curtains, it's essential to test it on a small, inconspicuous area to ensure it doesn't damage the fabric.

  • Dilute a small amount of mild detergent or vinegar in water or prepare the cleaning solution as per the manufacturer's instructions.
  • Apply the solution to an inconspicuous spot on the curtain.
  • Wait for a few minutes and blot it gently with a clean white cloth.
  • If the fabric remains unaffected, you can proceed with the cleaning process.

Testing the cleaning solution helps you avoid any potential damage to the fabric and ensures that it effectively removes the mould without causing discoloration or other adverse effects.

4. Apply the cleaning solution

Once you have tested the cleaning solution, follow these steps to remove mould spots from your curtains:

  • Fill a spray bottle with the diluted cleaning solution.
  • Spray the affected areas of the curtain, ensuring you dampen them without oversaturating.
  • Allow the solution to sit on the fabric for a few minutes to loosen the mould.
  • Do not let the solution dry on the curtains.

Applying the cleaning solution helps break down and loosen the mould, making it easier to remove during the scrubbing process. Be careful not to oversaturate the curtains, as excessive moisture can lead to further mould growth or damage to the fabric.

5. Gently scrub the affected areas

Using a soft-bristle brush or sponge, gently scrub the mould spots in a circular motion. Be careful not to scrub too hard, as it may damage the fabric. Focus on the areas where mould growth is most visible. 

The circular motion helps lift the mould particles and dirt from the fabric, allowing the cleaning solution to penetrate deeper.

Take your time and be thorough while scrubbing the affected areas. Ensure that you cover all the visible mould spots and pay attention to the corners and edges of the curtains where mould tends to accumulate.

6. Rinse and dry thoroughly

After scrubbing, rinse the curtain thoroughly with clean water to remove any residue from the cleaning solution. Follow these steps:

  • Fill a spray bottle with clean water.
  • Spray the curtain to rinse off the cleaning solution.
  • Use a clean white cloth to blot and remove excess moisture.
  • Hang the curtain in a well-ventilated area to dry completely.

Rinsing the curtain helps remove any remaining cleaning solution and loosened mould particles. Blotting with a clean cloth helps absorb excess moisture and promotes faster drying. Hanging the curtain in a well-ventilated area ensures proper airflow, preventing the formation of mildew or mould due to dampness.

It's important to allow the curtains to dry completely before rehanging them. Hanging partially damp curtains can lead to odour, mould reformation, and potential damage to the fabric.

More tips for effective spot cleaning

To ensure successful spot cleaning of mould from your curtains, keep the following tips in mind:

  • Address mould growth as soon as you notice it to prevent it from spreading further. Early intervention is key to minimising the damage and reducing health risks.
  • Avoid using bleach on curtains, as it may damage the fabric and alter the colour.
  • Stick to mild detergent or vinegar-based solutions.
  • Consider using a vacuum cleaner with a brush attachment to remove loose mould spores before spot cleaning. This step helps minimise the number of spores released into the air during the cleaning process.
  • For stubborn mould stains, you may need to repeat the spot cleaning process or seek professional assistance. Certain types of mould or deeply ingrained stains may require specialised treatments or the expertise of a professional cleaner.

By following these tips and guidelines, you can effectively remove mould from your curtains and restore their appearance and cleanliness.

How to help prevent mould on curtains

Mould growth on curtains can be a frustrating and unsightly problem. Not only does it affect the appearance of your curtains, but it can also pose health risks and compromise indoor air quality. 

To maintain clean and mould-free curtains, it's important to take preventive measures. In this section, we will discuss practical tips and strategies to help prevent mould formation on your curtains. 

Regular cleaning and maintenance

Regularly cleaning and maintaining your curtains is crucial to minimise the chances of mould growth.

  • Follow the manufacturer's instructions for cleaning your curtains, whether it's machine washing or dry cleaning. Different fabrics have specific care requirements, and following these guidelines helps maintain their integrity.
  • Vacuum your curtains regularly to remove dust, pollen, and other particles that can contribute to mould growth. Use a vacuum cleaner with a brush attachment to gently remove debris from the fabric's surface and folds.
  • Inspect curtains for any signs of leaks or dampness near windows or doors. If you notice any water stains or moisture accumulation, investigate and address the underlying cause promptly.
  • Repair any issues, such as leaks or inadequate insulation, to prevent moisture from entering your home and affecting the curtains. Fixing these problems helps maintain a dry environment and minimises the risk of mould growth.

By incorporating these practices into your routine, you can reduce the likelihood of mould formation on your curtains and preserve their cleanliness and longevity.

Proper ventilation

Creating adequate airflow and ventilation in your home is essential for preventing mould growth. Consider these tips for better ventilation in your home:

  • Open windows and doors regularly to improve air circulation. This allows fresh air to enter and stale air to exit, reducing the humidity levels inside.
  • Use fans or dehumidifiers to reduce humidity levels in areas prone to moisture, such as bathrooms, kitchens, or basements. These devices help control humidity and promote a drier environment, discouraging mould growth.
  • Use exhaust fans while cooking or taking a shower to remove excess moisture from the air. Proper ventilation during activities that generate moisture helps prevent its accumulation and subsequent mould formation.
  • Fix plumbing leaks or any source of water infiltration promptly. Moisture from leaks can seep into curtains and contribute to mould growth. Repairing these issues eliminates a potential source of moisture.

Opt for mould-resistant curtain fabrics

Choosing the right curtain materials can significantly reduce the likelihood of mould growth. Consider the following options:

  • Look for fabrics that repel moisture and are resistant to mildew. Some curtain materials, such as polyester blends or synthetic fibres, have inherent properties that make them less susceptible to mould growth.
  • Avoid heavy or thick fabrics that can trap moisture and impede proper airflow. Opt for lightweight materials that allow air circulation, reducing the chances of mould formation.
  • If you live in a particularly humid or damp climate, consider using mould-resistant curtain liners. These liners provide an additional layer of protection and can be easily removed and cleaned.
