The Complete Guide to Cleaning Roller Blinds (and Removing Mould Safely)
Finding mould on your roller blinds can be concerning, particularly when it appears in bedrooms, bathrooms or other areas of the home you use every day. The good news is that small areas of surface mould may be manageable if they’re caught early and the blind material can be safely cleaned.
However, removing mould from roller blinds requires more care than ordinary dust or stain removal. Excessive moisture, harsh chemicals and aggressive scrubbing can damage blind fabrics and coatings, while failing to dry the blind properly can encourage mould to return.
In this guide, we’ll explain how to deal with mould on roller blinds safely, when DIY cleaning may be appropriate and when it might be better to consider professional cleaning or replacement.
For everyday dust, marks and general maintenance, see our guide on how to clean roller blinds effectively.
Why Does Mould Grow on Roller Blinds?
Mould thrives in environments where moisture and poor ventilation are present. Roller blinds can be particularly susceptible when they’re installed close to windows where condensation regularly forms.
Common factors that can contribute to mould growth include:
- Condensation forming on windows
- High indoor humidity
- Poor ventilation
- Blinds remaining damp after cleaning
- Moisture becoming trapped when a blind is rolled up
- Roller blinds sitting close to damp glass for extended periods
Bathrooms, kitchens and bedrooms can be particularly susceptible because of the moisture generated by showers, cooking and overnight condensation.
Cleaning visible mould is only part of the solution. If the underlying moisture problem isn’t addressed, there’s a good chance the mould will eventually return.
Can You Remove Mould from Roller Blinds?
Whether mould can be successfully removed depends on how extensive the growth is and the type of roller blind you have.
A few small surface spots may be suitable for careful spot cleaning. Extensive mould growth, mould that has penetrated deeply into the fabric, or deterioration of the blind itself can be much more difficult to resolve.
Before cleaning, check the manufacturer’s care instructions if they’re available. Roller blind fabrics vary considerably, and a cleaning solution that is suitable for one material may damage another.
This is particularly important with blackout roller blinds. Their light-blocking coating requires gentler handling and shouldn’t be treated with aggressive cleaning methods.
If you have blackout blinds, read our dedicated guide on how to clean blackout roller blinds before attempting to remove mould.
What You'll Need
For a small area of surface mould, keep your cleaning supplies simple. Depending on the care instructions for your blind, you may need:
- Protective gloves
- A suitable face covering
- Clean microfibre cloths or soft sponges
- Lukewarm water
- Mild detergent
- A clean, dry towel
A diluted white vinegar solution may be appropriate for some roller blind materials, but don’t assume it’s suitable for every blind. Always check the manufacturer’s instructions and test any cleaning solution on a small, inconspicuous area first.
Avoid automatically reaching for bleach or strong mould-removal chemicals. These products may cause fading, discolouration or damage to certain blind fabrics and coatings.
How to Remove Mould from Roller Blinds
1. Fully Extend the Blind
Roll the blind all the way down so you can see the extent of the mould and access the affected area.
If practical, improve ventilation in the room by opening windows and doors.
Â
2. Check the Blind's Care Instructions
Before applying anything to the fabric, determine what cleaning methods are recommended for your particular roller blind.
This is especially important for coated, delicate or blackout fabrics.
3. Test Your Cleaning Solution
Test a small amount of your chosen cleaning solution on an inconspicuous section of the blind first.
Allow the test area to dry and check for changes in colour, texture or finish before treating the visible mould.
4. Gently Treat the Affected Area
Lightly dampen a clean cloth or soft sponge with a mild cleaning solution suitable for the blind.
Blot the mould-affected area gently rather than aggressively scrubbing it. Avoid saturating the material, as excessive moisture can damage some fabrics and make thorough drying more difficult.
For suitable materials, a diluted white vinegar solution may be used as an alternative, provided the manufacturer’s care instructions allow it.Â
5. Remove Residue
Use a separate clean cloth lightly dampened with water to remove any remaining cleaning solution.
Again, the aim is to use as little moisture as necessary rather than soaking the fabric.
6. Allow the Blind to Dry Completely
Leave the blind fully extended and allow it to air dry naturally.
Don’t roll the blind back up until every part of the material is completely dry. Moisture trapped between layers can create conditions that encourage mould and mildew to develop again.
What Should You Avoid When Removing Mould?
It’s tempting to use stronger cleaning methods when mould doesn’t disappear immediately, but this can permanently damage your roller blinds.
Avoid soaking the blind. Completely submerging fabric roller blinds can lead to warping, creasing and problems with drying.
Avoid aggressive scrubbing. Stiff brushes and vigorous rubbing can damage fibres and surface finishes.
Be careful with bleach. Bleach and strong mould-removal products can cause discolouration or damage certain fabrics and coatings.
Don’t use steam unless specifically approved. Heat and moisture can affect some roller blind materials, particularly coated blackout fabrics.
Don’t roll up a damp blind. Trapped moisture can encourage mould to return.
If gentle cleaning isn’t removing the mould, increasing the strength of the chemicals or scrubbing harder isn’t necessarily the answer.
How to Prevent Mould from Returning
Once you’ve treated the visible mould, it’s important to address the conditions that allowed it to develop.
Reduce Window Condensation
If you regularly notice water collecting on the inside of your windows, wipe it away rather than allowing moisture to sit against the blind.
Keeping a small gap between the blind and damp glass where possible can also help improve airflow.
Improve Ventilation
Ventilate rooms that regularly become humid. Use bathroom and kitchen exhaust fans and open windows where practical to allow moisture to escape.
Let Blinds Dry Before Rolling Them Up
After cleaning your roller blinds, always leave them fully extended until they’re completely dry.
Rolling damp material tightly around the tube traps moisture between layers.
Keep Up With Regular Cleaning
Dust and other debris can accumulate on blinds over time. Regular light cleaning makes it easier to spot moisture or mould problems early.
For general maintenance instructions, see our roller blind cleaning guide.
Can You Use Vinegar on Mouldy Roller Blinds?
White vinegar is commonly suggested for household mould cleaning, but whether you should use it on a roller blind depends on the material.
Some fabrics may tolerate a diluted vinegar solution, while other materials, finishes or coatings may react differently.
Before using vinegar, check the manufacturer’s care instructions and test the solution on a hidden area. Use it sparingly and avoid saturating the blind.
For blackout blinds in particular, extra care is required because cleaning products and excessive moisture may affect the blockout coating.
When Should You Replace a Mouldy Roller Blind?
Not every mould-affected roller blind can or should be restored with DIY cleaning.
Replacement may be worth considering if:
- Mould covers a significant area of the blind.
- The mould repeatedly returns despite addressing moisture problems.
- Staining remains after appropriate gentle cleaning.
- The blind fabric or coating has begun to deteriorate.
- You can’t clean the blind adequately without using methods that could damage it.
If you’re unsure whether a blind can be safely cleaned, professional advice may be preferable to repeatedly treating the material with stronger products.
Keep Your Roller Blinds Clean and Mould-Free
Dealing with mould early and controlling moisture around your windows can help keep roller blinds looking better for longer.
