How to Prevent Mould on Curtains

The last thing any homeowner needs is mouldy curtains, they look distasteful, no one wants to clean them, and they can even harm your health.

The ideal solution is to prevent mould from growing in the first place, which can be done by creating a clean, temperature-controlled house, free from damp. 

Regular cleaning:

As with most areas of home maintenance, the best way to upkeep your belongings is with regular cleaning.

To protect your curtains from mould, make sure you vacuum all the furnishings in your home frequently and occasionally dry-clean them.

Also, wipe down your windows, the surrounding areas, and Venetian blinds or shutters with warm water and detergent.

Try to buy window coverings which are aluminium or PVC for the bathrooms and kitchens, so they are resistant to moisture and easy to clean. 

You also need to make sure you’re cleaning your curtains properly too!

Regularly washing your curtains can help remove any mould spores that may be present and prevent them from growing.

Make sure to follow the care instructions on the label of your curtains to avoid damaging them during washing though.

Mould thrives in damp conditions, so it is a good idea to prevent moisture build-up by ventilating your house.

When you are home, open the doors and windows to encourage air flow and let sunlight in. Installing an exhaust hood above your stove in the kitchen, and an extractor fan in the bathroom, will help to remove steam from the house.

Don’t hang up clothes to dry inside, and check if your clothes dryer is vented outside, because if not, that could contribute to a lot of damp heat in the room. 

If your curtains do become wet, make sure to dry them thoroughly as soon as you can.

Hang them up to air dry in a well-ventilated area, and avoid leaving them damp for extended periods of time.


Another method of preventing the growth of mould on curtains is to regulate the temperature in your house.

By adding double glazing to the windows, and insulating the floors, walls, and ceilings, the building won’t be so affected by hot or cold weather.

If you invest in blinds or other window coverings to go under your curtains, it will also add more insulation and temperature control to the house. 

Use mould-resistant materials

When purchasing curtains, consider choosing ones made from mould-resistant materials, such as polyester or nylon.

These materials are less likely to absorb moisture than natural fabrics like cotton or linen, which can make them much more resistant to mould growth.

By choosing the right materials from the get-go, you can ensure that your curtains stay mould free, leaving you with more time to focus on more important things around the home!

Prevent moisture:

Even if you have a well-ventilated house, it is still a good idea to create the least amount of moisture possible.

Damp usually creeps in from outside on wet, rainy days through gaps in walls and window frames.

Water can also pool in places it shouldn’t if stormwater isn’t being discharged properly or guttering is malfunctioning. The solution is to frequently check your drainage and guttering and make sure everything is working smoothly. 

If you have curtains in your kitchen, especially near your sink, consider swapping them out for metal blinds or something that can better deal with the wet environment.

You can also consider investing in a humidifier for damp areas of the home to add another line of defence against moistur

How to remove mould from curtains:

For cases which aren’t too extreme, you can spray stain remover onto the mouldy areas, scrub with a stiff-bristled brush, and then machine wash on a low temperature with some baking soda.

Dry the curtains by hanging them up outside, don’t use the dryer as it will make the mould stains harder to remove.

If that doesn’t work, you can try the old fashioned method of covering the curtains with lemon juice and salt and rubbing the stains, then rinsing the material out.

However, the most reliable way to remove mould from curtains is to hire a professional curtain cleaning service which will ensure a thorough, long-lasting solution.

Treat mould fast

If you do notice mould growing on your curtains, the speed at which you act is just as important as the methods you use to get rid of the mould, so make sure that you get to work as quickly as possible before the mould starts to grow and spread.

Try to inspect your curtains regularly to see if you can see any mould growing.

What might just seem like a dark speck from far away might actually be mould, so it pays to be thorough!
