Mould does not just leave behind unsightly stains and a musty smell - it can put people's health at risk and damage your property. If it's growing on your fabric blinds, it is especially tricky to get rid of, too, and can cause them to deteriorate. 

Our professional mould removal services can help restore your property to a safe, clean home. Our Dewpoint-accredited technicians are available nationwide to remove all traces of mould from your home, including mould in the air. We operate 24/7, 365 days a year.

Keep reading to find out why mould is growing on your fabric blinds and how to remove it from them. 

What causes mould on fabric blinds?

Mould grows in damp, dark environments and can easily take root on your fabric blinds if the conditions allow. The main problem is the condensation that tends to accumulate on the windows due to temperature differences between the inside and outside of the home. 

This moisture can seep into your fabric blinds, providing mould with the conditions it needs to grow. Any dirt or dust trapped within the fibres of the fabric can provide mould with the organic material it needs to feed off of. 

Blinds also provide the dark conditions mould spores thrive in. They can only germinate without interruption from UV light which is lethal for them. Mould can grow quickly on porous surfaces, like fabric, too, as the mould can grow deep within its pores. 

Another issue is that blinds trap air around the window, leading to poor air circulation and ventilation which is a major cause of mould growth. 

The dangers of mould

Breathing in, touching, and ingesting mould spores can lead to an array of health problems like allergies, asthma attacks, and respiratory infections. Certain types of mould, like Stachybotrys chartarum generate toxic substances known as mycotoxins, as well, which have been connected to serious health conditions like sick building syndrome

Mould has a voracious appetite for organic materials which could include your fabric blinds, depending on what they are made from. As it feasts on the material, the structure weakens leading to permanent damage or even total ruin. As it can grow so quickly on fabric, it could then spread to other surfaces like the window sill and walls. 

You must have any mould removed from your home as soon as you spot it, but it can be particularly harmful if growing on your blinds. This is because you will need to come close to the mould when you open and close the window, or open and close the blinds.

How to remove mould from fabric blinds

As mould can grow in the pores of fabric blinds, it is especially difficult to remove. Traces of the mould could evade treatment and any left behind will simply grow back. A thorough mould remediation treatment is required using specialist equipment. 

DIY mould removal methods will not cut it. The effectiveness of household products like bleach, baking soda, and vinegar, is questioned when it comes to killing mould, and these cleaners can be too abrasive for gentle surfaces like fabric. Some products, like bleach, can even discolour and damage it. 

Fabric blinds are also very hard to clean. They are often not machine washable, like curtains, and mould can grow in hard-to-reach, high-up areas so getting rid of all traces of it safely is difficult. 

Removing mould from fabric blinds is dangerous, too. To clean the mould you will need to come in close contact with it and are very likely to ingest, touch, or inhale the mould. Scrubbing it can even aggravate the mould, causing it to release spores which you could easily inhale. 

To protect your health and ensure all the mould has been removed from your property, bring in mould remediation professionals. They will be equipped with the specialist equipment and products that gets deep into the fibres of your blind to extract mould spores without damaging the fabric.

How to prevent mould on fabric blinds

Although it is not recommended that you remove mould from your property or possessions yourself, there are lots of ways you can prevent mould growing in your home. Here are some of the most effective things you can do to keep mould at bay:

  • Keep humidity levels in check: Utilise dehumidifiers or air conditioners, especially in the more humid months, to keep the humidity level below 50%. Mould thrives in dampness and this step will starve them of their preferred environment.
  • Open the windows and blinds regularly: Keeping the area well ventilated can get rid of humid air and reduce condensation on your windows. Fresh air can also help dry blinds that have been made damp by condensation. 
  • Regularly clean your blinds: Dusting frequently can remove any dust and dirt which mould feeds off of. As you clean, you might be able to catch the early signs of mould growth, too.
