Mould. It’s nasty, it’s smelly and it looks downright disgusting. Now, imagine that one day, while cleaning your home, you discover that your beautiful lace curtains, the ones you paid a pretty penny for, are covered in ghastly fungi! Or maybe it has already happened to you? Well, no worries – we are here to save the day!
In this article, we are going to answer all of your questions on how to get rid of mould on curtains, including why it happens in the first place, and, as always – give you some helpful prevention tips.
Both mould and mildew can appear easily on, well, almost anything. Fungi need only a little bit of moisture (like condensation on windows), a warmer environment and a food source such as dust, dirt or organic material.
So, if you have a draftier window hidden behind a nice pair of curtains, don’t be surprised if you find nasty mould spots covering the fabric.
Generally, mould is a term that includes several types of identical nuclei. One of the fungus’s main characteristics is that it can develop beneath almost any type of material, penetrate it, and inflict some serious damage as time passes. That being said, mildew falls into this category, slightly differing.
Mildew grows on top of items and unlike some sorts of fungus, is easier to treat. Remember those slippery orange stains you found while last cleaning your bathroom? That is live mould. The same fungus spots can turn grey, which means that the mould is hibernating. What can “activate” the spores is warmth and sunlight.
Now that you know what exactly is mould and why it appears, we can talk about effective ways to remove it. Before you continue with the cleaning, note that not all curtains are made the same and have different washing requirements.
Check the label of your curtains before attempting to clean them. Some curtains can only be dry cleaned, and you need to know this in advance, so you don’t damage the material. Follow the provided instrusctions strictly for satisfying results.
So, with this out of the way, here are the 4 easy steps to treat curtain mould successfully:
The first part of the cleaning process is definitely not a pleasant one, but it’s still necessary. Get a hard bristle brush and start scrubbing the fungus. You need to remove as much of the nasty mould as you can.
We highly advise doing this outside, so the fungi spores don’t end up in another area of your home.
Once you are done scrubbing, roll up your sleeves – we are making a DIY curtain mould killer.
If you are a fan of eco-friendly homemade cleaners, then we should definitely mention the white vinegar and water recipe. It’s that simple, you just have to mix equal parts of the two in a spray bottle and treat the mouldy areas on your curtains.
Vinegar has antibacterial properties, so it should be effective enough to kill the mould. It’s good to wash your curtains after a few hours, though, to get rid of the smell and freshen up the fabric.
The next step of the cleaning process is to wash the curtains. You can do it by hand if you are dealing with net curtains which could be more delicate.
However, if your curtains’ label says they are machine washable, then this is the fastest and easiest way to deep clean them. Put them in along with your regular detergent and some fabric softener, and set your washing machine at a low temperature. 40 degrees will do the job.
If you are handling very sensitive fabrics that do not allow cleaning with water, then consider dry cleaning them. Mouldy curtains can be dry cleaned and the fungus successfully removed from the delicate materials. This can be done safely without having to worry about damaging the fabric.
Finally, take out the curtains from the washer and hang them outside to dry. DO NOT use your dryer to speed things up – there is a chance that you could actually shrink the curtains.
Carpets, like curtains, can become a breeding ground for mould growth. If your textile flooring is affected, read our post on how to remove mould from carpets.
Dealing with any kind of mould on any kind of area, surface, or material is nasty. The stuff looks weird, smells funny, and let’s face it – you can get goosebumps only by the thought of touching the fungi.
