The Complete Guide to Cleaning Venetian Blinds (and Preventing Mould)
Venetian blinds are a practical and stylish choice for controlling light, privacy and airflow in the home. However, their horizontal slats can quickly collect dust, dirt, grease and other marks, particularly in busy areas such as kitchens and living rooms.
Regular cleaning helps keep your blinds looking their best, while also preventing dirt from becoming difficult to remove. The right cleaning method will depend on the material of your blinds, so it is important to avoid harsh chemicals or abrasive cleaning products that may damage the finish.
How To Clean Venetian Blinds
Keeping Venetian blinds clean is relatively straightforward if you make it part of your regular household cleaning routine. A light clean every one to two weeks can help prevent dust from building up on the slats and make deeper cleaning much easier.
Before using water, detergent or another cleaning product, always check the manufacturer’s care instructions where available. It is also a good idea to test any cleaning solution on a small, inconspicuous area first.
To remove everyday dust, close the slats so they sit flat and use a soft microfibre cloth, feather duster or vacuum cleaner with a soft brush attachment. Work from the top of the blind downwards, gently wiping across each slat.
Once you have cleaned one side, rotate the slats in the opposite direction and repeat the process. Be careful not to press or pull too hard, particularly with aluminium blinds, as thinner slats can bend.
For a more thorough regular clean, dampen a soft cloth with warm water and a small amount of mild detergent. Wring the cloth out well so it is damp rather than wet, then gently wipe each slat individually.
Pay particular attention to the cords, tilt mechanisms and areas around the edges of the blind, where dust can accumulate. Once finished, wipe away any detergent residue with a clean damp cloth and allow the blind to dry completely.
If you also have roller blinds in your home, different cleaning methods may be required depending on their fabric and construction. See our complete guide to cleaning roller blinds for advice on regular maintenance, stain removal and dealing with mould safely.
How To Remove Stains From Venetian Blinds
Occasional marks and stains can usually be removed without deep cleaning the entire blind. The sooner you treat a stain, the easier it will generally be to remove.
Start with a soft cloth dampened with warm water. If the mark remains, add a small amount of mild detergent and gently wipe the affected slat. Avoid vigorous scrubbing, abrasive sponges and harsh chemicals, which may scratch the surface or damage the blind’s finish.
Grease can be a particular problem for Venetian blinds installed in or near kitchens. For greasy marks, a mild solution of warm water and dishwashing liquid can help break down the residue. Wipe the area gently and follow with a clean damp cloth to remove any remaining detergent.
For timber or timber-look Venetian blinds, avoid soaking the slats or allowing water to sit on the surface. Excessive moisture can potentially affect some materials and finishes, so use as little water as possible and dry each slat promptly.
If you are unsure whether a cleaning product is suitable for your particular blinds, test it on a hidden area before treating a visible stain.
How To Deep Clean Venetian Blinds
Even with regular dusting, Venetian blinds can benefit from an occasional deep clean. How often this is necessary will depend on the room, but blinds in kitchens, bathrooms and high-traffic areas may require more frequent attention.
Begin by removing as much loose dust as possible with a vacuum cleaner, duster or microfibre cloth. This prevents dust from turning into a muddy residue when water is introduced.
Next, wipe each slat individually using a soft cloth and a solution of warm water and mild detergent. Supporting each slat with one hand while cleaning with the other can help prevent bending or damage.
For aluminium or other moisture-resistant Venetian blinds, particularly dirty blinds may be easier to clean after being removed from their brackets. If the manufacturer’s instructions allow it, lay the blind on a protected flat surface and clean both sides carefully.
Avoid automatically soaking Venetian blinds in a bathtub. While this method is sometimes suggested, prolonged exposure to water can affect cords, internal components, finishes and some blind materials.
Timber Venetian blinds should generally be cleaned in place with a lightly dampened cloth rather than soaked. Follow the specific care instructions supplied with your blinds if you are unsure.
Once the blind is clean, remove any remaining detergent with a fresh damp cloth and dry the slats thoroughly. Do not close or raise the blind while it is still wet, as trapped moisture can encourage mould growth and may damage some materials.
How To Prevent Mould on Venetian Blinds
Mould grows where moisture and poor ventilation create damp conditions. Venetian blinds installed in bathrooms, kitchens, laundries and around windows affected by condensation can therefore be more susceptible.
The best way to deal with mould is to prevent the conditions that allow it to develop. Regularly ventilate rooms by opening windows where practical and using exhaust fans when cooking, showering or drying clothes indoors.
Condensation on windows should be wiped away rather than allowed to sit against the blind. Keeping the slats clean is also important because accumulated dust and grime can trap moisture.
After cleaning your Venetian blinds, always allow them to dry completely. Leaving damp slats pressed together can trap moisture between them.
If you notice a small amount of mould, avoid dry brushing it aggressively, as this may spread spores. Follow the manufacturer’s cleaning recommendations for the blind material and use an appropriate cleaning solution, testing it on a hidden area first.
Extensive or recurring mould may indicate a wider moisture or ventilation problem in the room. In these cases, cleaning the blind alone is unlikely to prevent the mould from returning.
For fabric window coverings, the approach can be different. Our guide to removing mould from roller blinds explains how to safely tackle mould while reducing the risk of damaging the blind material.
Keep Your Venetian Blinds Looking Their Best
A little regular maintenance can make a significant difference to the appearance and lifespan of your Venetian blinds. Dusting every week or two, treating stains promptly and occasionally carrying out a more thorough clean will prevent most dirt from becoming difficult to remove.
The most important thing is to clean according to the blind’s material. Use gentle products, avoid excessive moisture and make sure the blinds are completely dry when you have finished.
