Why Does Mould Appear on Curtains?
Mould and mildew are both types of fungus that thrive in damp, poorly ventilated spaces, and unfortunately, curtains can become a prime target. If your windows regularly get condensation, or if your curtains are in direct contact with cold walls or windows, they can trap moisture – creating the perfect environment for mould to grow.
Mould can cause health problems so if you are experiencing a lot of it throughout your home, it is best to consult a professional. But for less severe cases, all it takes is a few adjustments and some simple cleaning techniques to keep your curtains fresh and mould-free.

How to Remove Mould from Curtains
If you’ve spotted mould or mildew on your curtains, don’t panic – here’s how to deal with it effectively:
1. Take Your Curtains Outside
Before you start cleaning, it’s best to take your curtains outside if possible. This stops loose spores from spreading inside your home. Give them a good shake to remove any surface mould.
2. Brush Off Any Visible Mould
Use a stiff brush to gently remove as much mould as possible. Again, doing this outdoors is ideal to prevent spores from floating around indoors.
3. Use a Natural Cleaning Solution
Rather than using harsh chemicals like bleach, which can damage fabrics, opt for natural cleaning methods.
White vinegar is fantastic for tackling mould. Mix equal parts vinegar and water in a spray bottle, spritz onto the affected areas, and leave for an hour before dabbing with a clean cloth.
If your curtains are machine washable, pop them in the wash with a mild detergent and a cup of white vinegar to freshen them up.
4. Bathe Your Curtains
For delicate fabrics or curtains that can’t go in the washing machine, try soaking them in a bath with warm water and mild detergent. This is a gentle yet effective way to clean them without damage.
5. Drying is Key!
One of the most important steps is making sure your curtains are completely dry before hanging them

How to Remove Mould from Curtains Without Washing
If your curtains can’t be washed, don’t worry – there are still ways to freshen them up:
- Vacuuming: Use the upholstery attachment on your vacuum cleaner to gently remove and suck up loose mould spores.
- Spot Cleaning: Try dabbing affected areas with a cloth soaked in a vinegar and water solution.
- Steam Cleaning: A handheld steam cleaner can help kill mould spores while keeping your curtains dry.
- Airing & Beating: Take your curtains outside on a sunny, windy day, and give them a good shake or gentle beat to refresh them.

Preventing Mould and Mildew on Curtains
The best way to keep your curtains mould-free is to prevent it from forming in the first place. Here are our top tips:
- Improve ventilation: Open windows when you can, use extractor fans, or consider a dehumidifier in damp-prone areas.
- Keep curtains and blinds away from windows: If condensation is a problem, try positioning your curtain brackets slightly further from the window so air can circulate better.
- Avoid recessed blinds: Blinds that sit inside the window recess can trap moisture. Opting for Roman blinds that hang outside the recess can help.
- Choose washable, natural fabrics: If you’re buying new curtains, go for breathable, natural fabrics that can be easily washed when needed.
- Use mould-resistant sprays: There are special fabric sprays available that help prevent mould growth – just check they’re suitable for your curtain material first.
